Looks like Varget will be the best powder for me as well, somewhere in the 23.5-24 grain range. It also looks like I have one of the earlier Montanas that is going to take a bit of work to get sorted out to shoot well. Random flyers. Disappointing but I like the rifle so I'll do/have done the required work. I'll be starting with a bedding job and hope that does it. May end up with an 8 twist factory contour on it before it's all over. Hope not though. Anyone rebarreled one or have a barrel recommendation? I have a couple of Hart barrels on other rifles that have not disappointed.
