I recently did some load dev with 138gr Hammer HHT’s in my chopped and suppressed tikka 30-06. Tried Varget and Big Game. Both powders with each shot a different charge (finding pressure) put 12 or 14 bullets into just over an inch at 100. I was shocked that it didn’t care what weight or powder type… just basically same holed. 3130fps without pressure signs in the 19” ish barrel.
The recoil reduction over my 180/178gr loads was substantial and I think contributed to my better shooting. The rifle is 9.5lbs on the nose. I want to shoot an elk with it later this month.
