The copper Barnes even if hand loaded with LeverE powder don’t really outperform 150gr factory powermax, They are a decent bullet though. I’ve killed piles of game with both.

No 30-30 outperforms 150gr powermax on deer and hogs.

Don’t know about the imposed ranges of the above post but anything past 200 yards, I think the 140gr Hornady or 125gr Federal varmint rounds have the edge, sub 200 powermax 150gr is the one.

Almost any 30-30 is a 250 plus yard gun
