Re: Tikka T3
1-1/2" groups regularly is good accuracy. 3/4" groups regularly is why I like the Tikka T-3 rifles.
I bought the .270WSM and the gun shop gave me a box of Winchester 150gr PowerPoint ammo with it. I use handloads but I figured I'll use the factory ammo to break in the barrel. I cleaned the barrel, dried it good and fired a shot, cleaned-dried and fired a shot, again, again and again. (Not sure if it helps but I have had good luck over the years doing that routine) I bore sighted the rifle and was not turning dials, I just wanted to get the process done but those first 5 shots went into a 3/4" group albeit not dead center. With handloads it is a 1/2" rifle.
The '06 is no different.
Our forefathers didn't bury their guns. They buried those that tried to take them.
