simple way I suggest to people who ask me...
if you would use H 4350 in a load, then IMR 4831 is pretty close, just a little slower...
I don't think you can exceed SAAMI specs in an 06 sized case with it... I know you can't exceed SAAMI specs in an 06 with H4831...
but then for an 06, I am more along the lines of a 4064, 3031, RL 15, IMR 4895 kind of guy.... same with a 270...7x 57, 260, 243 .
