So, an incident a couple of days ago caused me to seriously reconsider settling for a .177 cal 1377: a raccoon killed and beheaded my pet rabbit, leaving me minus one pet and plus one gruesome animal to clean up (not the first -- the coon got one of my chickens as well). Could have left it overnight, the coon would have come back to get it, but I figured in honor of my rabbit I'll bury it
I'm thinking about buying the 1377 and converting it to .22 cal just to have some killing power behind it, as I don't have any other airguns in .22 nor any powerful enough in .177 to take down a raccoon. (LOL, I was even considering using my PVC spud cannon with 3/8" steel rod stubs sharpened at the end, camping overnight in my backyard!) I know the general consensus is that even a .22 1322 is barely adequate to take out a raccoon, but I assure you I will get a well placed shot. If a .177 13xx can somehow take down a raccoon (at say 650 fps), someone please tell me.
However if I make the change to .22, I'm sure I'll be missing the .177 as the pellets are cheaper, cheaper, cheaper... plus it's nice to have all my guns in a single caliber. And besides if this is going to be an all around gun, I'm not sure if a .22 cal is going to be the best to take along on trips and do a whole lot of plinking (wastes pellets).
Only other option I can think of is a caliber "quick change" -- like the kind you would find on a Beeman breakbarrel or a Talon, a quick screwing out of the barrel.
I heard that the 13xx requires a breech and bolt change, as well as the barrel, in order to become a .22.
Is it possible at all to have some sort of "quick change" barrel system to easily swap between .177 to .22 on a 13xx?
