Re: The .243 AI is a great Deer Cartridge
I'm not sure, but the 6xc might be better designed to handle hotter loads. I know some states have minimum caliber requirements for deer and elk. 25 for elk and 23 for Deer. Which frankly I wouldn't shoot a deer with a 22 cal, nor an elk with a 24 cal. But that's just me.
Pic out a spot,a single hair, and aim for that spot.
