Thread: Point of impact change

However just bought an ATEC H2 Supressor for it recently, same load now shoots just over an inch group with the ATEC on. Put the hardy back on, back to normal again. Going to have to do another seating depth ladder if i decide to keep the ATEC supressor on it. Any time you attach anything to the barrel it changes the barrels harmonics, sometimes for better, sometimes for worse.

What caliber were you shorting out of curiosity?

Tikka 300wsm. However my Tikka 6.5 PRC shot the same group size with no supressor, atec, and h2, just different points of impact. Go figure
