Re: 280 ack imp 40 degrees vs Nosler brass
I have an older 280AI done by Hart and before all the hoopla about the new SAAMI specs came out, I tried the Nosler 280AI brass. It resulted in severely flattened primers
This was with a known medium pressure load. No other harm done although there was probably extra thinning at the pressure ring which can be controlled by minimum shoulder setback when sizing fired cases
