I dig my 6mm ARCs, I have both a heavier 21" and a lightweight 18", usually stick with 100gr to 108gr, but they will sling 95gr SSTs and 85gr SGKs quite well also. The 108gr eld factory load shoots well in both of mine, haven't used that bullet on deer, but the reports are good. I think my next ARC will be a 12" SBR, although I'd like to add a Howa mini at some point too.
