I'm not interested in the 223 for hunting, I sure they are satisfactory for deer/antelope.
Shoot I used one for a sniper rifle and it falt works.
I don't don't have any hunting type rifles in 223 and with a ton of other rifles I dont see me buying or building one. I'll probably just stick to my Model 70 Featherweight in 257. Its worked for years.
However I do like the ideal of using my Marlin 94 in 357 for deer. I think it would be neat to take a horse back riding trip and bringing some a deer shot with that rifle.
