I'm shooting the 195 berger and 180 ELD out of mine. It likes H4831sc the best. H1000 is also good but I get compression with the big pills. If you are going to seek 1 or 2 powders I'd have H4831sc as a top candidate for bullets in the 160-180 range as it seems to be very forgiving in the saum. For the lighter copper 145g you may do well with H4350.
