Now I decided to tighten the rear action screw a bit and see if maybe just the ring tightening did the trick. Two more groups with the Fusion 120's, after a cool down between.
Not too pleased with this, but I know my accuracy is suffering possibly as much from bench technique as from the rifle. I can see minute movement in the center at each shot.
Now I just switch to 140 grn Fusion and fire three with no adjustment. You see those three on the left. I'm going to have to leave soon since I've spent a bunch of time already between cooling off the gun and waiting on some locals. I just go ahead and shoot three with the Hornady American classic 139 grn Interlock (group on the right)
Not too bad, both groups are low, but hovering right around 1.5"
Now, it's getting late, I have to get started to get ready for church, so I decide to try an adjustment again of the action screws. It seemed to shoot better with the front tighter so I try that again. I made a scope adjustment after measuring the Hornady group and shot this 3 shot 100 yard group that will cover with a dime. I chose the 139 Hornady over the 140 Fusion because I noticed the Hornady felt tighter in the chamber and I have experienced better accuracy from my Sako with factory ammo that felt this way. This is my last group of the day.I decided to leave on a positive note and was very happy.
I know I need more range time to confirm things and I need to get started loading but all in all , I think I won at Kimber roulette.
