This video demonstrates the impact of a Sig Sauer SRD 762 suppressor on the zero of a Tikka T3X CTR rifle chambered in 6.5 Creedmoor. Testing with both Hornady 129-grain and Federal 140-grain ammunition revealed a point of impact shift when the suppressor was attached. The suppressor generally tightened groups, but the shift varied between ammunition types.

Quick Summary

Adding a suppressor to a rifle can cause a shift in its zero, altering the point of impact. Testing a Sig Sauer SRD 762 on a Tikka T3X CTR (6.5 Creedmoor) showed approximately a 1-inch shift with Hornady 129-grain and a 0.5-inch shift with Federal 140-grain ammunition, while also tightening groups.

Frequently Asked Questions

Does adding a suppressor change a rifle's zero?

Yes, adding a suppressor can cause a shift in a rifle's zero, meaning the point of impact can change. This video demonstrates this effect on a Tikka T3X CTR in 6.5 Creedmoor using a Sig Sauer SRD 762 suppressor.

How much does a suppressor typically shift a rifle's zero?

The amount of zero shift varies depending on the rifle, ammunition, and suppressor. In this test, the Sig Sauer SRD 762 caused about a 1-inch shift with Hornady 129-grain ammo and a 0.5-inch shift with Federal 140-grain ammo.

Can a suppressor improve rifle accuracy?

While the primary effect tested is zero shift, this video observed that the Sig Sauer SRD 762 suppressor tended to tighten the shot groups for both Hornady and Federal ammunition tested on the Tikka T3X CTR.

What rifle and caliber were used to test suppressor zero shift?

The test was conducted on a Tikka T3X CTR rifle chambered in 6.5 Creedmoor. This platform was chosen to evaluate the impact of the Sig Sauer SRD 762 suppressor on its point of impact.
