[QUOTE="Catbrain, post: 2952587, member: 127536"] iD of sized cases is about 304-305. that seems reasonable. fired case neck OD is about 344 --- sized neck OD is 333. loaded neck OD is 333. factory loaded neck OD is 336-337. These are RCBS dies with the roll crimp type crimper. I normally use lee with the factor crimp dies. I compared the necks on some shot 308 with the necks on my shot 30-06---- i get about the same ID and OD. That makes me think the chamber is OK. Im thinking that the sizing die maybe is a little too small in the neck area. Im getting .009 between loaded round and fired round on the neck OD. That seems like a lot------ Just checked some 308 for the savage 10FP. 333 vs 344. about the same difference. Still don't understand why I got a double ripped case neck on the barnes bullet....... Is it normal to get a .010 diameter change on the neck when you size ? seems like that's working the neck too much..... [/QUOTE]
