I took my 18" *** to the range today. I started off loading 1 round at a time just to get it sighted in. it would not lock back the bolt most of the time. even with that i got it shooting 1" groups at 50 yards. took it out to 100 and dialed it in a little tighter. shot perfect. then i loaded about 15 rounds to test again. It would not strip off the next round. i had to load each one manually. I was shooting 110GR V-Max with 22.5 gr of IMR-4198. any ideas?
