Do's and Do Not's... Working with a Hornady 22 ARC die set here, and a Lee Factory 22 ARC Crimp Die - they are both available now. I have good news and bad news, depending on how much you reload, and how far you want to get into a 22 ARC, if you decide to. So, first 10 Grendel cases I tried, they were straight up, fired Grendel cases. Ran them through the 22 ARC Hornady deprime.resize die. I went 10 for 10 and crushed them. This is how they came out. Smashed the shoulders
