Home Forums Hunting & Shooting Handguns 10mm with 220 heavies

I didn't read all the responses but here is my thoughts. I have a Glock 20SF with a KKM barrel. I shoot the double tap 220's. I finished off a deer, killed a hog and one of my father in laws sick cows with it. It packs a punch but nothing like a 44 mag or even 45 colt imo. The fact that you can have 16 rounds on tap is pretty strong. The deer and hog were easy and a 22 mag could have handled it equally well.

Story behind the cow, kinda long but gives good data I think.
My FIL has an old 32 H&R revolver he calls Bessie that he uses to put down animals on the farm. He had a cow laying in the pasture (big bastard too) that he thought had died. Went out to drag it off with tractor and she was still alive. He put 5 32 slugs in her head. I was there for the weekend and he came and asked if I had a pistol and I had the 20. When I got to the cow it showed no signs of any bullet wounds or that it had been shot at all. Was mooing and just couldn't move. I put a 220gr hard cast between its eyes and and at the shot the whole cow shook like you'd snatched it with a tractor. Blood poured out of its nose and mouth and it was done. My father in law said holy [bleep] what the hell did you just shoot that thing with? I know a bullet to the brain drops anything but the shock that it had on the carcass when it hit kinda surprised me. After that I felt pretty confident that my 10mm would handle anything I ever needed to shoot with it.

I searched for sub-800 FPS loads with 200’s and didn’t find many options although I found 40 S&W loads with 200’s at ~725.

Anyone running heavies slow for practice?
