I'm using IMR 4831 with the 90 gr Accubonds in a Tikka which has 1 in 10" twist. I'm getting considerably less velocity than Nosler suggests in their loading data, but my primer choice and barrel length is different also.
Perfect , I have a couple lbs of 4831 & have always found it accurate .not too worried about speed .thx !
Ps , I believe your correct on the twist, will be interesting to see if it handles the heavier pill.
