These two cartridges are really close, just curious if anyone is shooting 6mm ARC out of anything chambered in 6mm AR?

It is close but I would not do it for headspace issues. If I were going to try making 6mmAR brass from 6ARC brass I would do the neck it up then down for a shoulder out of the neck to headspace on and you will wind up with short brass with that method. Too easy to just resize 6.5 Grendel to 6mmAR to go through that process.
Just my thoughts your may vary

I run 6.5Gr thru my 6PPC dies to size to 6mm Grendel which I believe is the same as the 6mmAR.
MAGA!

Just my thoughts your may vary This exactly. Look up chamber pressure and measure distance from chamber to face.
