280 AI brass question - To fire form or not

[Paul_R]

I screwed up and bought 100 pieces of Nosler brass in standard .280 Remington. I have Nosler .280 AI brass. If I fire form the .280 Rem, can I expect the brass be significantly different than the 280 AI brass? I don't want to have to work up loads because of differences in brass. TIA

Did the same thing once. If the manufacturer is the same, and the brass weighs the same, you should have identical results.

Great advice, thanks.

Well crap. Though both calibers are very consistent with themselves, within 0.5 gr., the .280 ai is a full 7.0 gr. heavier.
