7mm rem mag brass neck wall thickness

[Okiehunter67]

Is there a chart/ list somewhere with neck thicknesses of 7 mag brass. I did a few searches but didn't yield much. My main issue is with brass for hunting purposes only. I have some new prvi and winchester brass that the necks are .003" thinner than older brass of several manufacturers. It is small enough that after the first firing a standard die will not size it down enough to hold a bullet. Crimping, which I am not a fan of, gets about 20% to hold a bullet. The only solution I see is a bushing die with a .006" undersized bushing. I'm not short on brass. This is just frustrating. FYI, two sets of FL dies, and a hornady neck size only yielded the same results. I guess I'm lucky. I've been reloading for 40 years and have only ran on this twice, both times in the last 3 years since the world has gone haywire. TIA

it sounds like a bushing die with undersized bushing is your best option if you wish to use the brass.
