[QUOTE="MagnumManiac, post: 2177712, member: 10755"] DJFergus, I find new brass has more neck tension, which I do not like having a tension I do not desire. I put them all through a mandrel to get MY desired IR. Even then, I notice more resistance seating than on the same brass after the first firing even if I anneal. I have also noticed that the pressure ring is a lot tighter in the neck/shoulder juncture. My 25-06’s all have SAAMI short throats and all bullets are past the pressure ring. In new brass this area is tighter than a fishes butt, but I can’t do anything about it. Even on the second loading it is not as tight. I know the neck and body expand, but the die puts it back, maybe a little lesser than factory, but it’s hard to gauge that area. Cheers. [/QUOTE]
