Ruger’s Precision Rifle in 338 Lapua Part II Enjoyable range time

I find myself at a crossroads in life. On one hand, I really want to build a’65 Falcon with a 460 CI Boss Block Ford and race on Street Outlaws. On the other hand, I want to make a sandwich, but the kitchen is so far from the sofa. Living in a state of cognitive dissonance is a great segue into the bliss of procrastination. Why the picture of the engine? It is so pretty it makes me weep. Just give me a moment…

Back to business

Following Part I, I did not decide to participate in 1,000 yard, or meter, shooting competition and become a world famous marksman. See “…but the kitchen so far from the sofa”. However, I did spend more time with the Ruger Precision Rifle and the 338 Lapua Magnum and found it was a great piece of hardware for handload development.

The rifle has such repeatable precision, changing handload recipes in even small increments manifests itself in measurable group size and group shapes differences, as well as in changes to chronographed velocity. In most production sporters, the results of a couple of tenths in charge weights is often lost to a subject rifle’s typical group inconsistencies. So the performance of the Ruger Precision Rifle made the handloading component of the product rewarding and, yes, enlightening.

Special Bullets For Special Cartridges/Rifles

There are bullet designs specifically intended for magnum cartridges and high muzzle velocity that will perform close in, as well as at a distance. These are bullets with ELD, VLD profiles, very high ballistic coefficients, but with an ability to survive impact as close in at 100 yards without fragmenting and still reliably expand at 800 yards.

Joe, is the previous true? Empirical data tells me that between 50 and 200 yards this is very true, at least with and Berger VLD Hunting and Hornady ELD-X component bullets. Beyond those distances, I’ve collected no first hand data on bullets recovered from game or ballistic gel. However, I do trust the good reputation of both companies and significant, supporting prior experience with their products.

In any event, my interest is in the 338 Lapua Magnum and shooting distances between 50 and 300 yards, with those above 100 yards the exception. Subsequently, the bullet selection is limited to hunting bullets I have used, over those distances, successfully with the 338 RUM and 338-378 Weatherby, both cartridges analogous to the 338 Lapua.

The Speer bullets are for medium to large thin skinned game. The Sierra is for large game, as is the Nosler. Both the Woodleigh and Swift are partitioned core bullets with very tough jackets and do well with heavily boned, heavily muscled game. Within the group, only the Nosler is slick enough for protracted shooting distances the Ruger is capable of reaching, with the sierra coming close.

Ruger Precision Rifle/338 Lapua Handload Data

Warning: Bullet selections are specific, and loads are not valid with substitutions of different bullets of the same weight. Variations in bullet length will alter net case capacity,  pressure and velocity. Primer selection is specific and primer types are not interchangeable. These are maximum loads in my firearms and may be excessive in others. All loads should be reduced by 5% as a starting point for development where cartridges have greater than 40 grains in capacity and 10% for cartridges with less than 40 grain capacity following safe handloading practices as represented in established mainstream reloading manuals. Presentation of these loads does not constitute a solicitation for their use, nor a recommendation.

Handload Notes

Group size is not a statistical composite. Twenty rounds were fired through the Ruger and then single, 3 shot groups of each bullet type were shot. Six round, two bullet types and then moderate cool down… No mirage in front of the scope. Why no multiple group average? Every shot counts, including the first and most table showing a min-max group size out of five do not capture a rifle’s mechanical precision.

Changes in group size could be indicative of ammunition inconsistency, changes on barrel and ambient temperature and, certainly, less than perfect people who squeeze off the shots. Could the group appearing on the table tighten? Sure, especially if I became more proficient with the rifle/cartridge combination and I continued working to refine my handloads. Will any of that happen? No. I achieved my objective so, for now, I am done.

Essentially a 300 yard, point blank rifle with enough velocity and retained energy for anything encountered within 300 yards. The Ruger Precision Rifle and 338 Lapua are quite a combination for a serious competitor or a longer range hunter where the weight and size would be manageable. While I don’t have casual access to a range that supports extreme distance shooting. I believe I could get a good deal of use out of a 6mm Creedmoor or 308 Winchester version of the Precision Rifle and either would make for many good days at the range.

Ruger’s Precision Rifle in 338 Lapua Part I One of a number of excellent calibers

01/10/2021

The best way to improve a skill is to work at mastering associated extreme challenges. Practicing with a 44 magnum revolver makes a 357 magnum revolver’s recoil mild by comparison and easy to control. Extending shooting distances while getting in practice, beyond those anticipated within a planned application, sharpens marksmanship skills.

Extreme long range shooting provides an opportunity to sharpen marksmanship skills by amplifying the product of errors originating with a shooter and/or gear. The amplification makes it easier to isolate and analyze each problem and render appropriate solutions. Refinement of shooting skills and gear improves performance in long range competition, but improvement also carries over into hunting, recreational target shooting and competing at more moderate distances.

Would it not be terrific to have routine access to a 1,500 meter rifle range with interim 50 meter target positions…. and a truck full of ammunition? Or, if you are like me, a 1,640 yard range as metric is not my natural language. Change comes slowly to some. Twice as slow for me.

The Ruger Precision Rifle

In long range shooting, when a bullet enters a transonic zone and transitions from supersonic to subsonic velocity, it becomes destabilized. During that event, the bullet’s ballistic coefficient diminishes as the bullet begins to pitch and yaw; bullet nose moving up and down relative to the line of slight and bullet nose moving side to side relative to the line of flight respectively.

The combination of a Ruger Precision Rifle and the 338 Lapua Magnum push the onset of the transonic zone out to 1,400 meters. The combination is a pragmatic solution to a math problem, an engineering group’s expression of what it would take to push a 250 grain bullet to 3,000 fps and with enough retained velocity to have an effective range in excess of 1,400 meters.

Not to be typecast, the Ruger Precision Rifle is also available in: 6mm Creedmoor, 6.5 Creedmoor, 6.5 PRC, 308 Winchester, 300 Winchester Magnum, 300 PRC, as well as the 338 Lapua Magnum, so the Ruger Precision Rifle by chamber choice can be tailored to a specific application and none of them are slackers. The approximate supersonic to subsonic transition range for popular match ammunition, expressed in meters, in order of cartridges listed: 1200, 1300, 1350, 950, 1300, 1500, 1400.

The ergonomically designed Ruger Precision Rifle provides a high degree of reliable mechanical precision, while the cartridge selection provides the optimal ballistics to the shooter’s preference and for the application to be served. The subject firearm is the Ruger Precision Rifle chambered for the 338 Lapua Magnum.

Real Guns has previously evaluated Ruger Precision Rifle versions in 22 LR rimfire, 5.56 NATO, 243 Winchester, 6.5 Creedmoor, 6.5 PRC, 308 Winchester, 300 PRC. The 6.5 and 300 PRC were the most rewarding to work with because of the newness of the cartridges and the project handloading component. The 338 Lapua version, even though a mature cartridge, offered many of the same opportunities.

The Ruger Precision Rifle evolution

The Precision Rifle was a mid 2015 phenomena. Introduced as a in-line recoil path, bolt-action rifle, 1,000 yard hitter, in 308 Win, 6.5 Creedmoor and 243 Win. Others followed, each differing in configuration as an accommodation to caliber.

2019 300 PRC 26 1:9 15.2

 

A mid 2016 upgrade to existing models, changed the configuration to a handguard without a Picatinny rail to provide more clearance for scopes with large objective lens bells and a wider flat for more secure bipod mounting.  Additionally, a Ruger Hybrid Brake was added, along with an upgraded anodized aluminum bolt shroud.

In Mid 2017, a 5.56 NATO version was added and the an AI magazine system was adopted.

At the tail end of 2018, 338 Lapua Magnum and 300 Winchester Magnum chambers were added to the Ruger Precision Rifle line up. These models also received a heavy contour barrel with a Ruger Precision Magnum Muzzle Brake and revised handguard.

In April 2019 both 6.5 PRC and 300 PRC versions were added. Both are configured with a 26″ barrel and Magnum Muzzle Brake, however, the 6.5 PRC has a medium contour barrel versus a heavy contour for the 300 PRC.

A couple of quick points…

The Ruger Precision Rifle’s mechanical components and assemblies have previously been covered extensively and exhaustively. For anyone interested in that level of hardware detail disassembled, please see, “A Ruger Precision Rifle In 6.5 Creedmoor Part I” which addressed the barrel nut system, handguard mounting, buttstock and hinge system, receiver extension, trigger, etc. etc.

The 338 Lapua and 300 PRC versions of the Precision rifle are fitted with a heavy barrel contour, 0.875″ muzzle diameter, and a Ruger Precision® Rifle Magnum Muzzle Brake.The brake is very effective in reducing felt recoil and controlling muzzle jump and the four set screws along the top permit refining the way a specific firearm/shooter responds to muzzle rise with removal of any or all increase down force on the rifle’s muzzle. I am old, so I have been misinformed that a shooter must learn the characteristics and personality of a firearm, then learn how to adapt to shoot it well. For those who are trying to tame a firearm to conform to their personal attributes and personalities… well, here ya go.

A great source of entertainment can be found in reading social media approaches to brake removal. People are torching the brake, soaking it in hot water, using an impact wrench, etc. An alternative is to open the manual to page 18 and following the simple instructions. With the rifle checked for empty and the bolt removed and facing the front of the brake, put a large screw driver or similar through the brake vents so the brake body can be held in place. Using a 1 1/6″ open end wrench… not 7/8″ indicated in the instructions, turn the jam nut clockwise about a quarter of a turn, just enough to take the pressure off of the threads. Use the large screw driver to turn the brake assembly counterclockwise and both the brake and jam nut will come off together. How to hold the rifle while loosening the brake/jam nut assembly? My approach is to lay the rifle flat on a clean carpeted floor, sit on it at the action, and unscrew the brake. Other than some irregular surface discomfort, butt wise, no damage to the firearm. Yes, it is amazing that I can expend 300 words obsessing over issues surrounding a muzzle brake.

The 338 Lapua Magnum and 300 PRC versions of the Ruger Precision Rifle receiver rails have a 30 MOA downward cant, as opposed to the 20 MOA cant on other versions. The intent is to bias toward a raised muzzle so a scope does not run out of elevation adjustment when long range shooting. The rail is secured with 8-40 fasteners to better stand up to heavy optics under recoil.

The folding buttstock serves a number of purposes. Because this is an inline recoil rifle with an extended action and a long bolt, there must be a way to move the buttstock out of the way when removal of the bolt is required. So Ruger put it on a stout, solid locking hinge so the buttstock can be folded out of the way. The Ruger Precision Rifle accepts AR standard buttstocks and grips.

The Ruger Precision rifle’s bolt is a push feed design with three locking lugs and a 70º lift. The bolt body is one piece and, like the rifle’s receiver, CNC from pre-hardened 4140 Chrome Moly steel. Dual cocking cams provide additional mechanical advantage, which reduces cocking effort on bolt lift. The body is full diameter, the same as the circumference of the lugs, for added strength.The bolt handle has industry standard 5/16″x24 threads, permitting the use of any from a broad selection of aftermarket tactical bolt handles.

Pull length and comb height and position are adjustable by lifting up on the quick release cam levers and sliding associated surfaces to position of preference. No, “Cant Adj” is not the same as “Can’t Adj”. The pad is recoil absorbing and it can be canted, rotated, left or right 9º. All of the camming latches and QD attachment points can be swapped to the opposite side to suit preference.

Prepping for handloads

Previously working with the 338 Lapua cartridge and a bolt action rifle, the emphasis for handloads was for target work and bullets were selected accordingly. As the 338 Lapua also makes for an excellent big game cartridge, I am leaning toward working up handloads with expanding bullets suitable for hunting. The Ruger Precision Rifle’s high degree of accuracy, weight and stability make it an ideal platform for handload development. As a starting point and point of comparison…

A note on the ethics of long range hunting…

In 2019, J.C. Jarrell set the light Bench Rest 1,000 yard world record, 5 shots in the bullseye, a 2.83″ group. The following weekend, Jarrell put 10 shots inside of 6″, 6 of them inside 3″. Some time ago, I took a shot at a huge buck, 500 yards out… which turned out to be a relatively small deer at a much closer 275 yards. I was young, it was cold, I was hungry. I’ve since become much better at judging distances… and deer.

I do not know Jarrell… I don’t know a lot of people, but if he and I were in Alaska during hunting season, and stumbled on a herd of Caribou 600 yards out, I would not want to take a shot because I am not a skilled shooter at those ranges and I would not want to expend ammunition on a miss, or wounding an animal. Jarrell would have the credentials to attempt such a shot, I would not. In my opinion, it would be ethical for him to take the shot, it would be less than ethical for me.

The folks who burst into tears at the mention of a 300 plus yard shot, probably do not have the skill to take a 200 yard shot and are trying to judge all others by their level of limited competency. Often the same folks who pat the hide of a downed deer and thank it for giving itself up as food. Which is, of course, very silly because the deer did not volunteer to provide the hunter with a meal. If the deer could talk he would be cussing himself for being too slow to flee and would be telling our grateful hunter, “%##@&!!!”.

In summation, if a hunter has made his bones putting 5 shots into a 2.83″ group at 1,000 yards, he can make his decision to take a long shot within his range of competency. If you are like me, stick to smaller deer and shorter distances and lie like a rug when you tell the “longest shot” story.

The 338 Lapua in context… Which distortion of history would you like?

Yes, the 338 Lapua cartridge is a product of military origins, as are the 45-70 Government, 30-40 Krag, 30-06 Springfield, 308 Winchester, 5.56 NATO disguised as the 223 Remington, etc., etc.. They are all cartridges that have all been used for sniping, automatic weapons of the day and for general issue small arms, however, all have also made the successful transition to civilian applications.

As a young man, the 338 Winchester was the round that was too heavy for deer, but just about right for elk and big bear. It was also quickly discounted for use on any lesser game and slapped with the label of too hard of a kicker for most. Oddly enough it is still described in such a fashion. The 338 Winchester is based on a shortened and necked down version of the 375 H&H.

The 340 Weatherby is consistent with Roy Weatherby’s “more is always better” approach in that it is based upon a full length 375 H&H. Perhaps because it was affixed to the expensive Weatherby Mark V it never really achieved rock star status. It was chambered in the Mark V Sporter, a really good package for under $1,600, but ammunition is expensive, even for the reloader and velocity is only 100 – 125 fps greater than the 338 Winchester Magnum.

The 338 Lapua is based on a shortened version of the 416 Rigby. While the case head is 0.007″ larger in diameter than the Weatherby body above the belt, it is also 0.200″ approximately shorter than the 416 Rigby, which surrendered a good deal of powder capacity.

The 338 Remington Ultra Mag was, unfortunately, a part of a very high performance group of then new cartridges which included the 7mm Ultra Mag, 300 Ultra Mag, 338 Ultra Mag, and the 375 Ultra Mag. They were introduced just as Winchester was convincing the gun buying public that short was better. The 338 RUM is a terrific cartridge. I’ve owned them as a heavy barrel target rifle and as a shop built sporter on a Remington 700 action. The big down side is action length required and the lack of room for heavy bullets without surrendering case capacity.

The 338-378 Weatherby is a bucket full of smokeless powder and able to propel a heavy 300 grain bullet in a convincing fashion. I found shooting my Weatherby Accumark… invigorating and it remained so for the ten years it was actively put to work. It just seemed there was more work that could be done with 137 grains of powder held by each round.

My point is, don’t get caught up in the “What are you going to do with that ginormous 338 Lapua? It is meant for use as artillery and dinosaur culling!…!!” Is not. It is a moderate selection for perforating at 1,000 yards.

An now, a short brake

Yes, I know “break”. So some bullets will be selected, powder will be sought and primers will be secured. Hopefully, they will play nice together and some handload data will be the result. I like the hardware. It is beefy, aesthetically pleasing and well done on assembly. If I am bouncing around, I apologize. I am not a long range shooter by inclination, but there is a potential even for me with the Ruger Precision Rifle and I am trying to decide which version.

It might be that it is a rifle that is good for handload development; consistently accurate so one less variable in the process to worry about. It could be a challenge for me to engage long range shooting, to learn more about the influence of nature on shots at a distance; wind, temperature, varied elevation, and the dogged persistence of gravity. So I am writing, but mostly thinking aloud. Be back soon.
