Went over to the gas station, across from work, to get some smokes and a cup of coffee. I asked the old boy who owned the station how his deer hunting, with his son was going. He said, "Guess I'm going to have to get a new deer gun, probably one of those .243's like my son has. When he shoots them they go down right now. I shot at one last night 50 yds. away and we never did find it."
When I asked what he was using, and he said it was an old Enfield 30-06, I was surprised, until I saw his ammo. It was some old Winchester ammo, don't recall the specifics right now but, somewhere in excess of 220 gr. I ran back over to the shop, got a box of core-lokt 150 gr., and gave them to him.
The next morning, when I stopped for more smokes and coffee, he was grinning from ear to ear. "Guess I'll keep the ol' girl," was all he said.
I mostly bowhunt, these days, but when I do take a gun its either my A-bolt (25-06 Hornady 117 gr BTSP) or my 636 (.357 158 gr fp). Not because I think these are the
"best" calibers but just because I like the guns, themselves. They'll pretty much all do the job, under the right circumstances. Just look at how many deer are jacklighted with
.22LR.
