After reducing the cartridges I load for down to just the 223 and 260, I'm thinking about adding something 6mm.

I've considered the 243, 6BR and 6XC...but I'm curious about the 6x45. Use inexpensive brass, no time-consuming brass prep with commercial dies available, and very low recoil & report. Not going to compete with it, just paper/steel punching with maybe some whitetail and predator hunting.

Anybody running one? If so, I'm curious to hear your thoughts...especially compared to other 6mm offerings as well as the 223/223AI.

Is 2800fps with a 95gr SMK reasonably achievable in a 22" bolt gun?
