For your small game hunting, ie: rabbits, squirrel opossum, raccoon in ur opinion which calibers work best ,and using 45,50 cal is it too much ? How about mess factor? Ethics? Exclude small hogs and coyotes.
Actually looking to get the light hunter I like the 45 for hogs and those heavy air bolts .I love my air saber but that senaca ,dzam! Close to 600 fpsMy recluse 357 before I put in a power kit with a 105 gr would put out raccoon easy enough a well placed 22 cal 25gr would do the trick as well
Only coons that are gonna get up to 50# are pet coons, in the wild a huge coon is 25#, I trapped and hunted them for a long time the biggest one I ever caught/killed was 24# and was over 40 in long nose to tail huge skinny body. Guy I used to sell furs to told me he had something to show me when I took some furs in. He went in the backroom and came out carry something in both arms it was a raccoon that weighed 58#. Some guy jumped a persons fence in town and killed their pet coon and brought it to him to try and sell it, of course he called DNR and they arrested the fellow who ended up in all kinds of trouble.I'm in agreement with JimNM. I get good results on squirrels with my 19 fpe 177, and 18 fpe 22 but they do drop a few steps faster with my 32 fpe 22 and 25. But anything much beyond 30 fpe (possibly upper 20s) in a 22 is overfill in my opinion for small game. But this is for inside 50 yard shots and if you need to take longer range shots (and have the accuracy to do that sensibly) you would need more fpe. All 10 shots I've take with a 32fpe 22 passed through and 16 of 18 with a 32 fpe 25 also sent through a squirrel and exited. The other two were front of chest shots that ended up under the skin behind a rear leg.
I killed a small raccoon with my 32 fpe 22 but it took three shots. I killed another small one with my near 50 fpe 25 and it was one shot and immediate death. These coons weighed less than 10 lbs and they can get up to around 50 lbs. Much bigger animal and not easy to kill like a rabbit. Even with 50 fpe I think they need a brain shot to get immediate death.
