I found that 64 grains of Ramshot BG was golden with both 286 gr of standard bullets and 300 gr Swifts. For the 286 gr Barnes TSX, I found CFE 223 works well. I use CCI 200 primers... a "soft" primer. The 9.3 is very forgiving and very accurate. Nice to see yours is the same.
@CM McKenzieI really like them in the 62. They seem to pair just right with that cartridge.
