So, on my 300 PRC ADG brass after full length resizing once fired new brass I have 10% of the 100 dimpling at the shoulder. My first thought is what the heck went wrong on my part. After inspecting dies etc I can’t find anything out of the ordinary and have never had it happen with any other brass.

I honestly can’t figure out why it would do this. Maybe to hard ? If that’s a possibility. Not having enough give when resizing on specific individual ones. 🤷🏼‍♂️
Thoughts ?

Any idea why I haven’t seen it with any other brass ?
I thought about to much sizing lube but my process has always been the same
I assume that ADG brass may be more thoroughly annealed at the shoulder than the other brass you were using. Making it less hard and more pliable at the shoulder.

I anneal anyways before resizing so in theory I guess you can throw that possibility I had out the window

I’ll pay closer attention to the amount of lube on the ADG. Just have never seen it before with Lapua, Hornady or Winchester brass.
I have another 50 I have to run through tonight
