20in 6.5 PRC 140 class powders?

Not very fast. 2685 with factory barrel. But again stupid accurate

Ouch. Yeah, I wouldn’t be happy with that.

Really like 4831sc in my 20" pushing 140's at 2890, tiny groups, temp stable. I have n565 and h1000 I use in my 7 PRC but with how well 4831sc shoots I have no need to mess with it, 20-40fps won't make any difference on target.

I’d try 4831sc out of a 20” barrel.

I will add, if trying 4831sc buy atleast 2# of a matching lot or blend them before starting work up. I've seen some pretty wild lot to lot variations, always extremely accurate but I've seen my charge vary by as much as a grain to stay in a node.
