woofer;

FWIW, QL shows the 6x47L at 47.00 grains internal capacity, 2.800" COAL, and a (redlined) max charge (63kPSI) of H4350 at 41.0 grains (100% capacity) under a 105 A-Max for 3037 fps from a 22" tube.

Same (redlined) max charge of H4350 (63kPSI, 43.0 grains, 96% capacity) and 2.800" COAL for the .243Win and the 105 A-Max shows the estimate at 2993 fps from a 22" tube.

I'm not seeing the advantage, nor the difference, and would probably just AI the .243, load to 2.800", and run with it.

If I wanted "less is more" in the 6mm class, I'd look HARD at the 6mmBR or the 6PPC. The 6mmBR(Norma) should get you to 2800 fps-ish, with about 30-31 grains of RL-15, and the 6PPC to about 2600 with about 22-23 grains of RL-10x.

But, that's just me.
