I was at the range today with my brand new 700 vtr in .223. The first 40 rounds went no problem they were herters 55gr fmj the next 40 I had to slam the bolt down to lock it closed once I pushed the bolt forward I either had to force it back or slam it down it was stuck. These were 55gr jhp herters. Any idea why it's sticking I have tried no other ammo or went back to the fmj cause I shot all I had
