Looking for load data with 120/123 gr. A-Max or similar projectile and 4831 or 4831sc specifically but any help would be appreciated. My rifle is a 9-twist so I cannot shoot the heavier 140 Gr sized pills. I am willing to try other powders and such, but this is something that I have available already in my suppliers and I heard that it is a good powder for this chambering. Please share your experience with the 260 AI as far a seating date (off the lands, or a jam) Powder choices, primers, etc. Thanks!
