Yesterday I was out at our place doing some shooting. 50-55 degrees. I am shooting a 6.5-284 in a R700 action. On the seventh round that I loaded, my bolt was very, very hard to close. I was able to kind of bang it closed and the round shot fine. Again, I never had any problems lifting the bolt or ejecting the round, only getting bolt all the way closed. It then did it numerous more times throughout the day. These are loads using virgin Lapua brass, 140 gr VLD's. I have put 150 rounds through this rifle total. Anyone experienced this? Thanks.
