I got my new encore 308. I took it out this past week to site it in. I was using Remington 150 grain Ammo. The first shot was a misfire. I had 3 misfires out of a box. Encores first question was , Was I using a Hammer exstention? I was using one. I took it off and changed to high Scope mounts. I will be going back to shoot again this week. I hope this cures the problem. I will have to put several boxes through it now to get confidence that this wont happen again. I hate to be sitting in the Deer stand wondering if my Rifle is gonna fire. Anyone have any input on this?
