GSSF17, at 6'2" and 200 pounds you are a little light for a 27 or bear hunting with a switch.
I grew out of the following mouse guns. in order;
Iver Johnson TP22 .22 LR
High Standard Derringer .22 Magnum
AMT Back Up .380
Mod 60 .38 Special..still got it, see;
having a primary made them seem OK.. at the time. Lusted in my heart for Seacamp .32 between the .22 magnum and the .380. I've recently read that a sharp pointy stick is better than nothing.
Have fun with your mouser.
