I have an older non-accutrigger 10FP and just grabbed a newer accutrigger model. Both will feed any factory ammo but when I try my reloads I have problems with the newer 10FP. The bolt won't close on many of the rounds I feed it. But those rounds fit fine in the older 10FP as well as every other .308 that I own. I did buy the rifle used and I know the former owner pulled the barrel off when it was new, shot it with another barrel, then put the factory barrel on it when I bought it.

Does this sound like a headspace issue? My reloads fit in my headspace gauges perfectly. I do notice rifle markings on the bullets that won't feed in the suspect rifle. So I loaded a dummy round and kept decreasing the OAL and notice markings when the OAL was below 2.80, like 2.760.

Any thoughts.
