A 22" saum should go somewhere around 2950 with a 180gr with Re26. My 22" 284 can push 180s at 2830 easy as with re26. Saw 2900 in load development but she was well up there.
I have tried the 180s in my 22" Saum as yet. The 162s at 3050 kill so damn well even well out there around 750.
I have a 28 Nosler pushing 195s at 3100 too.
But the 7mm BM would be a nice option for sure if you could find some brass.
