Jevyod, by seating the magazine properly I'm not sure what you meant. Are you saying that you have the mag box seated against the receiver? If that's the case it needs to be free floated just a tad and I promise you your rifle will shoot better. You should be able to reach in with your fingers and the box should have just a touch of freeplay. I wish the best to you on your project. It's always fun wringing out the true potential of any rifle
Edited to say I didn't see that you shot .64 group. If it stays consistent I wouldn't worry about it however if accuracy is sporadic I would float the mag box
