I form 17 HH from Privi brass no problem. I also form 219 DW, that one can be a PITA. I also form 17 & 20 Garin from 30 Carbine and that makes the DW look like child’s play.
I’ve got a Bullberry Double End Die, an Annealeez machine that works fine, I think my buddy might have a form die set.
Would appreciate any tips and/or what to avoid.
