I use IMR4831 and love it behind 190 and 200 gr bullets.
208gr I've had mixed results but not enough trigger time on that group to really build up a load and see what powder or depth is better.
Had been using 7828 and H1000 on my bolt gun, but when I was having great success with IMR4831 in my 300 BAR and 300 Nemo Omen I switched the bolt gun to that and got better accuracy then the 7828 and 1000.
Recoil is a bit sharper than the slower powders and I'm not loading max.
220+ gr, I definitely use the slow powder.
