(rifle is a Kimber Montana... 1:9.5 twist)
Steve Olson from here on the fire worked up a few loads for mine and mine wasn't very fussy. Think everything ran under 1 1/2", with several loads 1/2-3/4"
Believe he tried 4831sc?? & R22. Didn't have great results with a 140g partitions. Rifle loved 150g ballistic tips, 150g partitions and 160g accubonds.
He's had a couple of the same rifles that while not bad, weren't as easy as mine was to load for.
Nosler brass and he used Winchester primers
I'll see if I can get him to chime in on his experiences
