New Upper: 6mm ARC or 6.5 Grendel?

[Gtscotty]

Upper arrived. Put it on a Colt lower until the PSA gets here. Scope is an SWFA SS 3-15x42 FFP Mil-Quad I had on the shelf.

Looks good, I have one of those 3-15 SWFAs on an 18" .223 Wylde and it's been solid.

Do you reload, or will you be shooting factory? If the former, AR-Comp, 8208 XBR or H4895 are good places to start for temp insensitive powders with 120gr bullets.

Thanks. Yes, I reload. Picked up a couple boxes of Hornady factory just to get a baseline velocity. I have AA2520 and Ramshot TAC on hand and a couple of boxes of 123 grain Hornady SSTs to start with.
