Description
The Weatherby 307 Range SF 338 RPM is the heavy barrel build chambered for Weatherby big game cartridge. It runs a 24 inch heavy contour threaded barrel in Tungsten Cerakote, a black adjustable stock with a graphite cheek piece, and an externally adjustable TriggerTech Field trigger. Weight is 8.2 pounds bare, overall length is 41.75 inches and capacity is five rounds from an AICS compatible magazine. The UPC is 747115463831. MAG5 Firearms lists it for hunters who want serious terminal performance and are willing to carry the weight that makes it comfortable.
A Big Bore That Is Actually Shootable
338 weatherby rpm is a Rebated Precision Magnum: a fat case head on a standard length action rather than a true magnum bolt face. The practical effect is 338 caliber terminal performance from a shorter, lighter action than a 338 Winchester Magnum needs, with slightly less velocity and noticeably less recoil. Putting that cartridge in a heavy barrel bolt action rather than a lightweight hunter is the decision that makes a Weatherby 307 Range SF 338 RPM genuinely pleasant to shoot.
The 8.2 pound weight is the point rather than a compromise. A 338 in a six pound rifle punishes the shooter and produces flinches; the same cartridge in an eight pound rifle is manageable for most adults from a rest and will not build a flinch across a practice session. If you intend to actually learn a big bore rather than sight it in and hope, a Weatherby 307 Range SF 338 RPM is the sensible version to buy.
As an elk and bear rifle the combination is hard to argue with. A 225 to 250 grain 338 bullet delivers penetration and energy that a 30 caliber has to work hard to match, and it is a genuine answer for moose, big bears and elk at realistic ranges. On deer sized game it is far more than is needed and it will cost you meat, so be honest about what you hunt before buying a Weatherby 307 Range SF 338 RPM.
Action, Fit and Honest Limits
The Weatherby Model 307 action is a two lug, fully cylindrical design with an M16 style extractor and tool-less bolt disassembly for field cleaning, built on a Remington 700 footprint so stocks, chassis, triggers, rails and mounts from the wider market fit. The triggertech field trigger adjusts from outside the stock, which is a genuine convenience on a rifle you will be tuning to a heavy recoiling cartridge.
Stock fit matters more on a big bore than on anything else. Comb height and length of pull both adjust on a Weatherby 307 Range SF 338 RPM, with length of pull running 13.5 to 14.25 inches, and getting both right is the difference between a rifle that recoils and one that hurts. Set the comb to your scope, set the length of pull for your clothing, and do it before you zero rather than after.
Two honest constraints. Ammunition is proprietary Weatherby and a relatively new cartridge, so availability is thinner than a 338 Winchester Magnum and prices are higher. Buy enough of one load to sight your Weatherby 307 Range SF 338 RPM in, build a drop chart and hunt two seasons. Second, the muzzle is threaded 5 8 by 24 but no brake is fitted, so budget for one if you want reduced recoil. MAG5 Firearms does not stock or transfer suppressors.

Who Should Buy It
A Weatherby 307 Range SF 338 RPM is for the hunter who goes after elk, moose or large bears and wants a big bore they can actually practice with rather than one they dread. The extra weight over the lightweight Alpine models is the feature, not the drawback, and the adjustable stock makes it fit properly. Full factory specifications are published by Weatherby.
If you want the same cartridge in a rifle light enough for long walks, the 307 Alpine ST in 338 RPM saves over a pound with a carbon stock and a factory brake, at the cost of noticeably sharper recoil. If you want easier ammunition sourcing, a 300 Winchester Magnum is the pragmatic alternative. Browse the rest of our rifles to compare.
Practical notes. Fit a scope with generous eye relief, because a heavy recoiling cartridge and a short setup is how people get cut. Choose a bonded or monolithic bullet built for heavy game. Buy a spare AICS pattern magazine. And do your practice from field positions in limited round counts, because a flinch developed at the bench with a Weatherby 307 Range SF 338 RPM will follow you into the field.
