Only considering accuracy. I like Lyman 150 gr. SWC and load it with the same charge of Bullseye that I use with 148/150 wadcutters. For a more serious activity I use a stiff load of 2400, which I won't post here as it is on the North side of what is recommended. 50 years ago it was below max and I have always had good luck with the load. Truth is most loads will shoot better than I can hold, at my stage of life.
