I’m A 100grainn tsx and 45grain H4350 practitioner. Loaded so they just fit in the magbox of my 7 and my 722. That’ll definitely have some of the last relief groove showing maybe all of it depending on case trim, and it’ll stone one. Basspro has IMR4451 so I’m about to go get it and a couple boxes of tsx’s.
