I always used Win231 for plinking, especially in .38's and .45's. 1 pound of 231 will go a long, long way with lead bullets, just keep them under a grand (I like about 900fps). For a big bang I love 2400. Max out 2400 and it is a thumper. You may want to get a newer book though as some say that the newer 2400 packs more punch than the old stuff so you may not want to use one of the newer books.
