have a question about 6br neck tension. I have a hall action with a Abc barrel on it, 8 twist shooting 108g Berger. It is a no neck turn and currently I am using a 267 bushing with the Bullet roughly 8-10thou in the lands. Base to ojive is 2.840C and after messing with it last night I realize if I chamber a dummy round like this after extracting it the bullet is being pushed back in the case roughly 7thou. The gun shoots great, would you guys leave it or test with more neck tension. I did the same test with a 266 bushing and it didn’t move, but you could tell it was slightly tougher to close the bolt.
