Home Forums Hunting & Shooting Hunting Rifles Touching up the barrel crown....brass screw???

Here's a picture or two of a target I shot this evening with the Tikka. I used Federal fusion factory ammo. The first 2 shots went into literally the same hole, and the 3rd was about 0.75" from the center of the first hole. The second pic is of the same gun shooting my 100gr Sierra PH load. It measures 0.7"
The 3rd pic is of my Win 88 .308 that I couldn't get to shoot into better than 2" at 100 yards. Today I free floated the barrel after touching up the crown yesterday. This is the target showing the results after two sighter shots, and then a 5 shot group.
