I have limited experience shooting ARs in .223. What caliber would you guys suggest for use in informal paper punching out to 500m and shooting hogs,the pineywood rooter kind)? I like the idea of the 6.8 shooting 115 gr Corelokt bonded or maybe the 110 VMAX. In 6.5 calibers, I think of the 123s for use in both. For the 6mm calibers, I think the 105s+ would be the choice. What are your opinions?
