Loading 1 of these for a buddy. I had no powder that would work for such a cartridge. Initial investigation looked like Lil Gun might be a good fit so I picked up a lb. Initial results I was not impressed.....some wild velocity fluctuations from shot to shot, and WAY fast, but eventually by being extra careful, along with neck sizing only, I got it to work. Not sure in hindsight this was the best powder, but I'm stuck with it for now, so I'm glad it's working.
9.9 gr's showed the best groups in this M25 Savage, both when bumping the shoulder, and with neck sized only. Using the 20gr Nosler Varmageddon's.
I ran the neck sized loads back through the chrono and had an extreme spread of 32fps over 5 shots. Much better. Averaged 3675. 4 shot group laying over the truck hood was .450, 5'th shot was out making it just under 3/4" but I do believe that shot was me.
Double checked it on the bench and 5 shots came in just under 1/2". Woo hoo, relieved. I'll load a bunch up for him.
