Oops.....I left out the technical stuff. It is a K-frame BUT I save most magnum use for things that attack me...hogs, bad guys, and so forth. It is a 4" model 19, my duty revolver. Oh, and I talked to the rancher last night and he said he has used a .357 blackhawk for years and, on small hogs, went with the 125 JHP or the 145 Silvertip through lungs, and on big ones, a factory cast load(didn't specify).
