I used to use the Winchester 64 grain and the Barnes X.
I have since switched back to more appropriate chamberings for deer.
My .444, .303, 6.5x55, .308, and .30-06 deer loads just won't fit into my Magpuls, no matter how hard I shove.
I must be doing something wrong.
I respect the animals I hunt, even the hogs, too much to use a varmint round.
.223 has it's uses. It's a fantastic varmint, coyote, and beaver round.
It's about as well-suited to deer as .30 carbine.
Even less so, at short ranges.
I hear it's a great round for zombies.
Sadly, I only see zombies in movies, video games, and TV shows.
