Frequently Asked Questions

What accuracy was achieved with match grade ammunition on the SIG SPEAR?

Testing revealed a 2-inch shot grouping with match grade ammunition on the SIG SPEAR, expanding to approximately 3 inches when accounting for a potential flyer, demonstrating improved precision over standard loads.

What was the average velocity recorded for the tested ammunition in the SIG SPEAR?

The SIG SPEAR rifle, when firing the tested match grade ammunition, achieved an average velocity of 2,664 feet per second. This velocity was noted as slightly slower than previous rounds but utilized a bullet with a higher ballistic coefficient.

How does standard deviation affect accuracy in firearms?

A lower standard deviation in muzzle velocity, such as the 11.7 recorded in the test, ensures more consistent shot-to-shot performance. This consistency minimizes vertical spread on the target, leading to tighter and more predictable groupings.

What optics were used during the SIG SPEAR accuracy test?

The accuracy test on the SIG SPEAR utilized the Arken Optics EP-5 GEN2 5-25x56 scope. This high-magnification optic allowed for precise aiming and detailed analysis of the shot groupings on the target.
