I have a couple 20 Practicals, one on a AR platform that I won in a shooting match and I liked the cartridge enough that I built a 20P on a bolt action that goes out a lot.
I didn't like the AR for the fact that I had to hunt for brass out in the field and it is hard enough to make that I rebarreled the AR to 223.
The 20P on the bolt is a superb rifle for hunting coyotes flat shootig and I can hold on fur to 300 yards and save the pelts. Mine is ust a little heavier than I like so I have another in the works that will be built on a Rem 600 with a 20" sporter barrel.
