Is .22 magnum ammo/rifles affordable down there? I have used one for years for small game (head shots) and hogs, all with FMJ bullets, usually CCI Maxi-Mag. I went to the newer Remington 33gr Vmax stuff for prairie dogs, and it is a gee-wiz killer! ha. I would think a good Marlin in .22 magnum would be about perfect. However, I've used both the .223 and the .204 and both are sweet. I especially liked how flat that .204 shot! To me, it felt like less noise/etc than the .223 but shot as flat as a 22-250.
