Was just down at my loading bench finishing some 6.5-284 loads and then moved on to my 6mmAI. It occured to that necking up the 6mmAI to 6.5 would be about the same cartridge. My load for the 6.5-284 was 50.8 grs H-4831sc and my load for the 6mmAI was 50.2 grs H4831sc. Seems the going up to 6.5 should give a fuller case than in the 284 case. Enough difference to make another wildcat probably not but would different than the other guys anyway. Your thoughts?
