I'm non-typical.
As my video in the other thread showed, I believe accuracy should be judged by real-life simulation, not sitting on some bench with your elbows on a table.
Never have owned a bolt action or AR rifle.
I prefer steel-case TulAmmo from Russia because every round always goes bang, since it is made to machinegun specs.
Sorry, not the answers you were looking for.
As I use a rifle for hunting, I go for bolt action rifles. Love the 30-06, 243 Winchester and my custom 280AI. Hand loading has made all three “fun” guns. If I had to pick one cartridge for everything, the old ‘06 would be it! Check this pic. Recently shot with my 1959 Browning FN Safari bolt action.
