Howdy Will, I see you're from Breckinridge. My Mom's side of the family is from up there. She has a sister still living there and my Grandmother and Grandfather have both moved out to Hubbard lake. (Not much lake up there anymore)
Anyway, I've got about 300 acres out in Woodson, great Dove huntin, and OK coyote hunting. Might need to meet up sometime!
Anyway, I only ever shot 1 deer with my .223, a doe at 50 yards. I hit her right between the eyes with a 55 grain Gameking BTHP. When I was a kid, I popped a small fork horn at about 90 yards with a .222 using remington 50 grain PSP. It dropped him in his tracks, taking out his heart and not exiting.
I do however shot quite a few pigs with the .223. I've found that 55 grain Remington PSP's work pretty good on 'em. Most have been head shots, with a few body shots....so far none have taken another step.
On the other hand, my go to gun has and always will be my Rem. 600 Mohawk in .308
I popped a 320lb boar this year with it. He was standing broadside at 40 yards and I driled him right behind the shoulder with a 150 grain Remington Core-Lokt (can ya tell I like Remingto Ammo?) At 40 yards a HUGE amount of dirt exploded off of him up in the air, this fat @$$ porker didn't miss a beat, he wirled and ran out of sight. The only thing I could here was the sound of low hanging limbs popping as he ran through them.
I waited 10 minutes and went to look for him. Found him about 75 yards away from where I had fired. NO BLOOD! A very slight trickle on his hair from the entry wound. His skin and fat had just closed up the hole. There was NO exit wound, and this was at 40 yards with a .308
In this situation I was very glad that I didn't have my .223
Why didn't I shoot him in the head you might ask? Well then I wouldn't have his perty bleached skull and 3 inch tusks adorning my desk top!
Put yer bullet in the boiler room on any deer you shoot and you'll be fine! Watch out for that shoulder blade though.
