.223 BC vs 6mm BC
Ok... so I was reading up on some .223 stuff and some 6mm stuff over at 6mmbr.com anyhow... I came across that the 6mmbr can shoot the same bullet of same weight as fast or faster than a .22-250. The catch is though, with a higher BC...
So sure enough I go look up the BC value of 55 grain ballistic tips in .223 and 6mm. Sure enough the 6mm is higher. Why? how? wouldn't it be lower because its fatter? I guess there is more to it than that. .267(.223) vs .276(6mm) |
