180 gr STARTING load for 2400 is 11.1 gr & 1012 fps in a 4" bbl. Max load is 12.3 @ 1163 fps. I've never had bad accuracy with 2400, just plenty of noise & recoil. The powder I hate to love, & love to hate??? Blue dot should do slightly better. NOT LISTED with Lyman, but I use 6-6.5gr of unique (NOT SAYING YOU SHOULD) in my 162 gr cast which should get you to 1,000 fps+
