.22 LR, L, short, or shotshell in a High Standard Sentinel, 4" barrel.
Got it about 14 y.o. or so, living in a state that is now extremely antigun!
Worked well while cruising in the ponds and swamps, fishing, and assorted other activities by myself.
Dad did mention that 2 legged critters could be more trouble than 4 legged or things that slithered, so keep that in mind, about your surroundings!
Wish I still had it. Think the lure of a K22 got to me !
