Odd thing. I recently have needed to stun some domestic pigs to be slaughtered. I do not posses a captive bolt gun, which the standard tool used by abattoirs for this purpose. I was thinking that a small revolver would do this job nicely.
I was thinking a Lyman 358429 in 38 special loaded with about 3.5 grains of Unique. The Lyman manual lists 3.7 as the suggested starting load, but I cannot think of any reason to back it off a bit more. Perhaps even down to 3.0 grains. This bullet I would think would easily penetrate through a pig's skull and perforate its brain and exit into the ground.
I would like to to be as quiet as possible otherwise. I know the position to place the muzzle (at the intersection of an imaginary X drawn between the base of the ears and eyes).
Anybody have experience with this or know if it can be backed off even more?
