Ruger Precision Rifle in .338 Lapua Magnum Field Tested

Ruger Precision Rifle .338 Lapua .300 Winchester Magnum

The Ruger Precision Rifle goes big — major Magnum-size big. Back in October we revealed that Ruger was releasing new .338 Lapua Magnum and .300 WinMag versions of the Ruger Precision Rifle (RPR). These Magnum RPRs feature longer, stronger actions, and some key upgrades, such as a +30 MOA rail and beefy muzzle brakes on the end of the 26″ 5R Barrels. These are pretty impressive rigs for the money — $2099 MSRP, with the “street price” well under $1700.00.

So how do these Big Rigs shoot? GunsAmerica.com recently answered that question, testing a .338 Lapua Magnum RPR with a variety of factory ammo types. GunsAmerica’s tester Clay Martin, a skilled former military sniper (retired from 3rd Special Forces group), shot the rifle from prone off bipod. With Hornady 285gr Match Ammo, Martin drilled two 3-round groups that both measured right around a half-inch. With some other ammo, results were ugly, but the 285-grainers showed that the gun could shoot. (Five-shot 100-yard groups with Federal 300gr ammo were around 1.3 MOA — see photo below).

Overall Martin came away impressed: “My respect for the RPR in .338 Lapua Magnum is high. If it will shoot ½ MOA at 100, there is no reason to think it won’t at any range a match bullet will fly [provided you call the wind right]. Despite the uber-manly caliber, the gun was fun to shoot. The muzzle brake and weight do a great job of taming recoil[.] For a .338 Lapua-caliber rifle, I can’t think of a single better option below $5,000. If you have been waiting to step into the big boy rounds, this is a golden opportunity.”

RPR Magnums Boast 5R Barrels with Big Brakes
The new RPR magnums feature hammer-forged, chrome-moly heavy-contour 5R barrels fitted with tunable muzzle brakes. Those fat, large-port brakes will certainly reduce recoil and muzzle jump but we wouldn’t like to be shooting beside the .338 LM RPR — expect lots of side-blast. The new RPR magnums feature 18″ free-float anodized handguards with M-LOK accessory attachment slots on all four sides. Integral QD sling attachment points eliminate the need for additional adaptors and a flat-bottom 1.50″ dovetail is compatible with RRS S.O.A.R. and similar QD systems.

The .338 Lapua Magnum RPR features a 1:9.375″ twist rate while the .300 Winchester Magnum model features a 1:9″ twist rate, both of which stabilize long-for-caliber projectiles. These rifles ship with two, 5-round AI-style magazines. As with all RPRs, the bolt is a 3-lug design with 70-degree bolt lift.

Angled +30 MOA Rail and Adjustable Stock Standard
ELR shooters will be pleased that the new, magnum-caliber RPRs ship with a +30 MOA Picatinny rail. That will help give shooters enough elevation to shoot out to 1500 yards and beyond. As with other Ruger Precision Rifle models, the magnums feature a folding stock with adjustable comb height and length of pull. The Ruger Marksman trigger is user-adjustable between 2.25 and 5 pounds.
