Great guns, but, 'sorta few and far between, and I'll bet most have been rode hard and put away wet, and under a pile of leaves for the winter, usually.
The companions will kick you if you insist on using big loads. I like to think I'm smarter than the gun, and use what will work, and feel good.
I've burned up a bunch of 1 oz loads in mine. Recoil wasn't/isn't a problem.
