The .300 Winchester Short Magnum was designed to deliver .300 Win Mag performance in a short-action rifle.
Winchester achieved that goal with notable efficiency. The .300 WSM pushes a 180 grain bullet at 2,970 fps from a 24-inch barrel, which is within 100 fps of the .300 Win Mag from a barrel two inches longer.
The short action design provides practical advantages: stiffer, more accurate bolt lock-up, shorter and lighter rifle packages, and a case geometry that feeds in short-action rifles without the long cartridge handling of the standard long-action magnum.
The performance is identical to the .300 Win Mag at hunting distances. At 500 yards, the two cartridges diverge by less than 30 fps in velocity and less than 40 foot-pounds in energy, which is not a meaningful distinction in hunting field conditions
These five picks are matched to the .300 WSM application with those specifics in mind.

#1 Vortex Viper PST Gen II 5-25×50 – Best Overall
The .300 WSM’s ballistic performance at 600 to 800 yards is capable. The Viper PST Gen II 5-25×50 is the scope that lets a .300 WSM shooter use that capability through a precision optical system.
The EBR-2C FFP reticle is accurate at every magnification from 5x to 25x.
For a .300 WSM shooter making wind holds at 8x or dialing for elevation at 20x, the MRAD or MOA subtensions are correct and consistent. That precision system matches a cartridge this capable at extended range.
The zero stop turrets handle .300 WSM recoil and provide accurate 0.1 MRAD clicks. At 25x the glass gives genuine resolution for 600 to 800 yard precision work.
Eye relief at 3.7 inches clears the minimum safe threshold for magnum recoil with proper ring placement. The 30mm tube with a 20 MOA base gives adequate elevation range for .300 WSM at extended distance.
This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.

Our Take
The Viper PST Gen II 5-25×50 is the right scope for a .300 WSM rifle used for precision long-range shooting or extended-range hunting past 400 yards. It delivers the tools the cartridge’s capability deserves at the best value in the Vortex precision lineup.
#2 Vortex Viper HS 4-16×44 – Best for Hunting
The Viper HS 4-16×44 is the hunting scope matched to the .300 WSM’s characteristics. The 4-inch eye relief is the first important specification on a magnum rifle.
The .300 WSM generates recoil comparable to the .300 Win Mag at 28 to 33 ft-lbs depending on rifle weight. Four inches of eye relief provides the safety margin that sustained shooting with a short, hard-recoiling magnum demands.
The XD glass delivers excellent low-light performance for big game hunting at dawn and dusk. The 4-16x range handles mixed terrain hunting from close timber shots to 400-yard open basin opportunities.
The Dead-Hold BDC reticle provides practical field holdovers at hunting distances. The 30mm tube and 16.7 oz weight keep the overall rifle build manageable for a mountain hunting application.

#3 Vortex Strike Eagle 4-24×50 – Best Value FFP
The Strike Eagle 4-24×50 gives a .300 WSM shooter first focal plane capability and 24x magnification at a price below the Viper PST Gen II. The AR-BDC3 FFP reticle is accurate at every magnification setting for ranging and holdovers.
At 24x the glass handles .300 WSM precision work to 700 yards in most conditions. The exposed zero stop turrets provide 0.1 MRAD precision input.
Eye relief at 3.5 inches is the shortest on this list and requires careful attention when mounting on a .300 WSM. The 50mm objective provides strong light gathering for field use.

#4 Vortex Diamondback HP 4-16×42 – Best Budget Pick
The Diamondback HP 4-16×42 is the budget-honest option for a .300 WSM hunting rifle used at practical hunting distances inside 400 yards. The 4-16x range covers the full practical hunting application of the .300 WSM for most hunters.
The Dead-Hold BDC reticle gives practical holdovers at hunting distances. Multi-coated glass handles standard daylight hunting conditions well.
The 1 inch tube limits elevation adjustment range for long range dialing but is adequate for hunting applications. Build quality handles magnum recoil and zero retention is consistent.

#5 Vortex Razor HD Gen III 6-36×56 – Best Premium
The .300 WSM at 800 to 1,000 yards is a legitimate precision application that the Razor HD Gen III is built to support. The APO glass at 36x delivers the optical quality that 1,000-yard shooting demands.
Reading mirage for wind, spotting bullet trace, and calling impacts at distance all benefit from the APO glass quality in ways that no other scope on this list can provide. The EBR-7D FFP reticle gives the most detailed precision shooting system in the Vortex lineup.
The 34mm tube provides maximum elevation adjustment travel for the significant elevation input the .300 WSM requires at 1,000 yards. This scope is backed by Vortex’s VIP warranty: unconditional, lifetime, and transferable to the next owner.

Did You Know? Winchester introduced the .300 WSM in 2001 as part of a series of short magnum cartridges designed to challenge the established long-action magnum market. The WSM case uses a large diameter, short body that was optimized for powder combustion efficiency. The design goal was to match long-action magnum performance in a package that cycled through a short bolt stroke. The .300 WSM approximates .300 Win Mag performance and offers a lighter, shorter rifle platform, though it never displaced its predecessor in overall popularity.
Frequently Asked Questions: Best Vortex Scope for 300 WSM
How does the .300 WSM compare to the .300 Win Mag for scope selection?
The scope selection is identical; both cartridges produce similar recoil, similar effective range, and similar precision potential. The same eye relief requirements, magnification ranges, and optical quality tiers apply to both.
What eye relief is required for a .300 WSM scope?
A minimum of 3.7 inches, with 4 inches preferred. The .300 WSM produces recoil comparable to the .300 Win Mag. The same safety considerations apply.
Is the .300 WSM a better cartridge than the .300 Win Mag?
Neither is better. They produce identical performance at all practical distances. The .300 WSM offers a shorter, lighter rifle package. The .300 Win Mag offers better barrel life, wider ammunition availability, and more established reload data.
What is the practical effective range of the .300 WSM for hunting?
With quality loads and a capable shooter, 600 yards is the practical ceiling for elk-sized game. For most hunters, 400 to 500 yards is the ethical ceiling given the shooting skill and conditions required to place shots at greater distances.
Does a .300 WSM need a 34mm tube scope for adequate elevation adjustment?
A 30mm tube with a 20 MOA base is adequate for most .300 WSM precision applications to 1,000 yards. A 34mm tube provides additional margin for high-arc cartridges or competition formats where maximum adjustment travel is a competitive advantage.
Verdict
The .300 WSM delivers .300 Win Mag performance in a short-action package, and the scope selection reflects that parity. For precision long-range shooting to 800 yards, the Viper PST Gen II 5-25×50 is the best answer.
The FFP reticle and zero-stop turrets match the cartridge’s precision potential. For hunting-first use where field performance matters, the Viper HS 4-16×44 delivers the right eye relief margin and XD glass quality.
FFP performance at a price below the PST Gen II, the Strike Eagle 4-24×50 is the honest middle ground. For budget hunting inside 400 yards, the Diamondback HP covers the practical range at an accessible price.
And for the precision competition or extreme long-range build, the Razor HD Gen III removes every optical limitation. The .300 WSM is a capable cartridge in an efficient package. Give it a Vortex scope that keeps up.
