Frequently Asked Questions

What is counter-boring on a Mosin Nagant rifle?

Counter-boring is a gunsmithing process where the last few inches of rifling at the muzzle are drilled out. This is typically done to remove corrosion or damage, effectively restoring the rifling and improving the rifle's accuracy, especially on older firearms like the Mosin Nagant.

Can a Mosin Nagant M91/30 PU Sniper be accurate at 800 yards?

Yes, this review demonstrates that a Mosin Nagant M91/30 PU Sniper can achieve practical accuracy out to 800 yards. Success depends on factors like a functional optic, quality hand-loaded ammunition, and potentially modifications like counter-boring the muzzle.

What ammunition was used for the Mosin Nagant accuracy test?

For the practical accuracy test, hand-loaded 7.62x54R ammunition was used. Specifically, reloads featuring 174-grain Sierra MatchKing (SMK) bullets were chosen to maximize the rifle's potential accuracy at extended ranges.

What are the limitations of the PU scope on a Mosin Nagant sniper rifle?

The primary limitation of the 3.5x fixed power PU scope, especially at longer ranges like 650-800 yards, is its low magnification. The reticle can begin to obscure the target, making precise aiming challenging, although spotting and adjustments can still yield hits.
