525 Beartooth

I’ve been playing around with these things recently. So far I’ve been using RL7 and H322. RL7 has been my go to powder for 45-70 regardless of bullet. H322 seems to be better suited to these slugs. I’ve gone as low as 35gr and as high as 41gr. It seems that the groups got tighter the higher I went.
Recoil was......quite frankly....absurd. I was shooting from a lead sled at 100yds and while these will make a great hunting round I don’t think will shoot them from a bench much.
Btw, mine actually scale at 539-541. Oal is 2.55” and I’m using a Hornady press and RCBS chargemaster scale. Like this combo!
The attached group is right at 2”. I think I can shrink it some minus the flinch. Plus this gun needs a little trigger work.
