I use AA#5 for loading my .45ACP loads and was going to be setting up my 21SF to handle occasional .45 Super loads. I'll be using 22lb. recoil springs and a Lone Wolf supported chamber barrel. Do any of you who load for the .45 Super in the Glock 21 use AA#5 to work up loads in this round? Any ideas on what loads data you can share on this? Thanks!
