I own a Savage .308 F/TR which has had the barrel replaced with a Pacnor. I've had a few problems with closing the bolt when feeding some handloads, factory is fine but necksizing will jam about a third of the sized cases. I recently checked the COL with a Hornady COL gauge and found that with several bullets, notably Sierra Match King 168 grain and 155 grain, the COL is only 2.7" which is a tad short. The rifle performs adequately, three quarter minute groups with factory GGG match and better than that with handloads. Anyone have any thoughts on the COL?
