I've got a .50 Hawken with the 15/16" barrel. Shooting conicals, it hit the face too hard and accuracy wasn't the greatest with the .50 PRB.
So now it's got the 32" GM .54 slow twist barrel and only shoots PRB. Really like that combination. It wears a tang mounted aperture sight and is a tack-driver. Recoil is a non-issue.
Also have a .50 Greyhawk (stainless & plastic New Englander) that's my go-anywhere/anytime utility gun. With a 24" barrel, it's light, quick, and handy in blind, treestand, or on a stalk. It's also easy to care for, near indestructible, and comfortable shooting conicals. It has a tang mounted aperture sight and is accurate with conicals out to 100 yards. Come deer season, it's what I'm most likely carrying. Only one fault: It's not a .54.
There's also a .54 Renegade that hasn't been shot yet. If it doesn't work out as-is, there's a slow twist .54 GM RB barrel waiting to go in. If THAT doesn't work, there's always the .58 TC barrel I picked up before the Custom Shop closed.
