I have a 1 in 9 twist blank I want to use for local matches and was wondering if .223 would be a good choice for barrel longevity etc. I am open to suggestions from you fellas and would appreciate your comments and the reason you chose the caliber(cartridge ) over other choices. Thanks in advance. The blank is a medium varmint barrel and will finish at 24" 's!
				
			 
	








 ;D  I'd suspect that the 223 would have longer barrel life all other things considered equal, but have no data to back that up.
