Mauser 105 update
After spending a little time at the range a few weeks ago with the Mauser 105, I am very pleased to report that the rifle will produce 1″ 10 shot groups at 50 yards consistently using CCI SV ammo, CCI blazer, and Aguilla SSS. The CCI SV was the best, averaging a little under 7/8″ for all 3 of the 10 shot groups I fired with it.
With the suppressor, using any type of subsonic or standard velocity ammo, the gun is just stupid quiet. I assume that the slight cushioning effect of the open bolt operation helps with that.
