Hot Dang! this critter is made for pistols!
A growing group of folks here in MT swear by the use of a .32 cal percussion rifle for body shots on Gobblers. Following this line of thought, the .22 mag should do well. It is in fact a common enough Turkey *rifle* here, as is the .22 Hornet, .222 & .223.
OH MY! It just dawned on me there are so many good rounds for this:
17 M2, 17 HMR, 5MM REM, .204 Ruger .22LR, .22WMR .22WRFM, .22 hornet, .222, 222mag, .223, 32 S&W, .32 H&R, 25-20, 32-20, .30 carbine, 7.62x25 Tokarev .38S&W, 38-40 38 SPL, .38 super, 9MM, 9x18 MAK .40S&W, 10mm. . . The list goes on! Even the .32acp &
.380 acp would be great if the guns are accurate enough!
For rifles, I'll pick: .30 carbine in an M-1 carbine
9mm largo in a "Destroyer" carbine
'03 Springfield w/.32acp "Pedersen" device
.32 flintlock
.75cal Brown Bess w/.25cal "swan shot" on the fly!
(but this involves stalking turkeys so you must be ina private area)
For pistols: Ruger single-six hunter in .22mag or .32mag
Ruger blackhawk in .30 carbine
my S&W M-15 .38 spl
TT-33 Tokarev, 6'' Navy Luger, or Mauser C-96
in their 7.62 chamberings.
Hammerelli target pistol in .32 S&W
.32 flintlock
1851 colt in .36 cal
