New Rifle 30 Nosler neck OD question

[xmanpike]

I have a new Cooper rifle in 30 Nosler. Bought brass (ADG), bullets, powder etc. Bought the competition s-type Redding bushing die. SAAMI Specs tell me that loaded cases should be like .340-.343, but the ones I'm loading are closer to .337. Is this unusual? I did not resize the new brass. Any help is appreciated.

Very normal to be undersize, all cartridge, not just yours. .344" is maximum for your loaded rounds outside neck diameter.

The brass sets the final deminsion and it seems like every manufacturer makes their necks just a little different. It's one reason to run only one brand if your using bushings that run 20 plus each.

I'm not here to offer help. I'm only here to tell you how jealous I am and that I hope to read plenty of range reports about this rifle in the future. I am VERY interested in 30 Nosler.
