On paper an AR10 seems like the easy answer. In reality my experience with them so far is that they are much more fickle than the AR15. I'm just starting to finally get my 6.5 creed match rifle dialed in.Got two (.243 win & 6.5 CM)….. no luck yet, too much vertical at best load so far.
A couple years back I did shoot a 2388 with an 18” Wilson Arms .233 and some Nosler 77 Blems (sorted of course) from American Reloading @ 0.12/bullet.
I think I may go back to working on my 6x45 ar15 upper….. or maybe a 22” .233 with 75 grain eldm’s.
