Frequently Asked Questions

What accuracy can be expected from an ATI Mosin Sporter rifle?

With proper accurizing, including stock bedding and relief, an ATI Mosin Sporter rifle can achieve impressive accuracy. Eric from Iraqveteran8888 demonstrated a 5-shot group measuring approximately 3/4 of an inch at 100 yards during his range test.

What handload recipe was used for the ATI Mosin Sporter range test?

The handload recipe detailed for the ATI Mosin Sporter included Winchester brass, CCI bench rest primers, 180-grain Sierra GameKing projectiles, and 52 grains of IMR 4350 powder. This combination yielded excellent results.

Is the Vortex Crossfire 4-12x40mm scope suitable for a Mosin-Nagant?

Yes, the Vortex Crossfire 4-12x40mm scope proved to be a reliable optic for the ATI Mosin Sporter. Despite being an entry-level scope, it held zero well on the heavy-recoiling Mosin-Nagant platform during testing.

How can the accuracy of a sporterized Mosin-Nagant be improved?

Improving the accuracy of a sporterized Mosin-Nagant, like the ATI Mosin Sporter, involves meticulous stock bedding and relief. Ensuring the barrel and action have consistent, non-binding contact with the stock is crucial for harmonics and precision.
