Most of the hunting bullets aren't real jump sensitive, so as long as the twist is fast enough most of those will be GTG in either 243 or 6 CM.
I had built a fast twist 243 AR and it worked good with the 107 SMKs which aren't real jump sensitive.
I basically went off the advice of a nationally ranked PRS/ELR shooter and "load 107 SMKs to mag length and go shoot".
I decided to get a bolt gun to shoot the PRS style stuff so I didn't have to chase brass. Long story short I stumbled across a Gen2 Ruger precision at such a discount I could buy dies and brass an be money ahead.
Using the same powder bullet combination I went from SD in the low 20s to single digits. Between that and the availability of factory long range match ammo my AR got rebarreled to 6 CM.
In keeping with the 6mm Max theme after running some numbers I could easily see it replacing my Valkyrie if it would shoot the 90 or 95gr VLD type bullets, my home range only goes to 960 so I can step down a notch on ballistic coefficient and still get there with a little added velocity.
