If you do take a deer with the 45 please post results. I hunted a few game animals with a 45ACP in the 80's and was unimpressed. Took an antelope, a javalina and finished up a few others with the 45. Bullet technology has come a long way since then.
Done a good bit of killing with the acp and haven’t found it lacking on deer and hogs . Bullet selection and placement matters as I’m sure you know .
Here’s a 230gr black talon I recovered in the offside hide of a doe after busting through both shoulders .
