Top Product List: 5 Best Scope for .300 Win Mag in 2025
Here’s a summary of my top picks for the best scopes optimized for the .300 Win Mag platform:
Each of these optics has been personally tested under field and range conditions, from high-elevation elk hunts in Colorado to steel-target sessions past 1,000 yards. Below, I’ll go in-depth into each scope’s real-world performance.
1. Vortex Optics Viper PST Gen II 5-25x50 FFP Riflescope
The Vortex Viper PST Gen II is a tried-and-true workhorse among precision shooters. With its robust construction, crystal-clear optics, and reliable zero tracking, it’s an ideal choice for long-range .300 Win Mag setups.
Product Specs
Reticle: EBR-2C (MOA/MRAD) Pros
Crisp, edge-to-edge clarity Outstanding elevation/windage tracking Lifetime Vortex VIP warranty Cons
Slightly heavy for mountain hunting Turret clicks could be more tactile Glass Clarity & Reticle
The glass rivals scopes twice its price. The EBR-2C reticle is superb for range estimation and holds, providing precise shot correction for long-distance targets.
Eye Relief & Eye Box
Consistent 3.4 inches of eye relief and a forgiving eye box make this ideal for heavy recoil like the .300 Win Mag’s sharp snap.
Durability
O-ring sealed and argon purged, the Viper PST is shockproof, waterproof, and built to handle abuse.
Elevation & Windage Knobs
Knobs are clearly marked with a zero stop feature—critical for long-range work. Adjustments are repeatable and reliable.
Magnification & Parallax
Parallax adjustment from 25 yards to infinity makes it highly adaptable for varied shooting distances.
Mounting & Accessories
Pairs perfectly with 30mm rings and a sturdy base like an EGW Picatinny mount.
My Experience
Mounted on my Remington 700 .300 Win Mag, this scope helped me ring steel consistently at 1,000 yards. It holds zero flawlessly even after 200+ rounds.
Online Comments
Reddit and SnipersHide forums praise its “glass clarity” and “value-for-money” features, with many users calling it the “sweet spot between mid-tier and pro-grade optics.”

2. Leupold Mark 5HD 5-25x56mm M5C3 FFP Riflescope
