Thanks fellas. I'd be looking at the shotshells in 38 spl. I guess the best way to find out is to buy a box and do some pattern tests. I CC a 357 snubbie and I have a feeling that the pattern out of that on a snake could be "iffy". For hiking though, I'd probably be carrying my 357 New Vaquero (5 1/2") or my S & W (6"). I would assume the longer barrel would maybe keep the pattern tighter but who knows without doing a test on cardboard.
I've used 22 shotshells for years - mainly on gophers. They work pretty well up close but too far out and you might just as well through up a handfull of dust.
If a pair of '51 Navies were good enough for Billy Hickok, then a single Navy on my right hip is good enough for me . . . besides . . . I'm probably only half as good as he was anyways. Hiram's Rangers Badge #63
