I shoot mostly cast in mine. Look @ Lyman Rl book. I use 245 gr cast w/ 14 -16 gr of Blue dot or unique, 300gr with 18 to 22 gr of 2400. I think the old lyman book shows a 232 gr cast and 17 gr of unique as an accuracy load @ 1745 fps. I use also 20 gr of 2400 and a 245 gr 429421 bullet which gives me a 1 1/2 group @ 75 yards, have taken many deer with this load. Lyman is the best source for cast loads that I have found.
