I've got a few; 550s in .375 and .416 Rigby, a .17 HMR fullstock and a 452 Varmint.
I found the 550 Magnums to have soft barrels and trigger parts. It was supriseingly easy to shoot the barrel out of the .375. Triggers seem to need resetting every other time you pick it up. Actions smooth up with use, the .375 got real nice about the time the barrel died.
The rimfires benefitted greatly from shareing a single YoDave trigger kit.
