Well almost. .243 is a very good round but from what I’m reading this 6mm arc is pretty nice, in regards to being better over 5.56. As we have read in comparison to the 6.5 Grendel and in comparison to the .308 in terms of distance I like it. Is it a great deer round. I wouldn’t say great, comparable to .243 but better in terms of BC, from what I’ve seen. I like it in terms of a defensive weapon on long range and punching paper. Could be used for deer and predator hunting. The 6mm has a slightly higher BC, on the 108gr on the .243 100gr though.6mm and .243 are the same ballistic coefficient.
