So I had a grendel but got rid of it and yet I still have laying around a nearly full pound of AA2520. I see looking through AA's load data that it's suitable for what appear to be limited applications from 17rem to 223 to 308 but no data for 6x45mm. I'm wondering if it's suitable for 55gn or 80gn bullets in 6x45mm. The stuff flows brilliantly through a dispenser and while I won't buy any more of it I'd like to use it up.
My only other option is to experiment with my .45Cinderblock and see if I can't get someone to run a quick test through quickload or similar software and see what it'll do with about 14 grains of 2520 and a 200gn LRN and a magnum pistol primer or large rifle primer in a case with the same dimensions as a .45acp (I use .460 rowland brass cut to .888 in a converted swedish mauser).
So, anyone want to run a sim for me on the .45 load (this is for my custom .45 Cinderblock, not .45acp so no panties in a wad, it's just a thought not a plan). How about anyone that's got some idea of the utility of AA2520 and 6x45mm with light or medium weight bullets?
