Afraid their 22 ARC won’t be twisted as fast as I’d like when they get it.
probably will shoot the donor as is for awhile. It’s still difficult to find any 6 ARC brass let alone the newer 22ARC. I could make either I suppose but I’ll probably just shoot it in 6.5 until brass is easier to get.

Don't speculate when you don't know, and don't second guess when you do.
