I'll be loading 308 for a dpms with a 1" match grade carbon wrapped barrel. I believe its a Broughton barrel. I've been using a lot of varget 42.2 with LC brass and a 168 hornady match BTH. I scored this 4320 in metal cans unopened which are in excellent shape .

I have had good results with IMR4320 in .22/250 and I believe a couple other cartridges. I don't use it much anymore, but keep a few pounds on hand for when powder gets hard to find.
The only thing I would worry about is if you used Varget for the temperature insensitivity. IMR4320 is more temperature sensitive than Varget. I treat it like a lot of ball powders. Loads worked up in the warmer months only.
For a lot of people this doesn't really matter though. Just wanted to point that out.
