.45ACP barrel length?

[Alan in GA]

JUST when I forget this project,,,someone posts again and brings it BACK up!
Glad you did, this just sounds like TOO much fun.
Remember, the 45 ACP round would be fun BECAUSE of so much factory ammo of so many variations [loads] out there. Probably still some old military surplus ammo out there???
My only balking point is the price of a good .451" barrel blank. Fitting will be in house as many of my buddies own lathes and such [me included] Wish I could find a factory take off to fit to my Ruger 77 Mark II switch barrel 'fun' gun.
I want to try some "45 CB Caps" for plinking.
I actually DO need something for close range coyote culling,,could this be it?
I have to be able to control ricochete, tho. Don't want a roundish 45 ball bouncing thru a subdivision after I shoot a coyote in a nearby pasture or farm wood plot.
