Yep, still have my RB .454. 5 years in and many many rounds downrange. I really have no idea how many rounds of hot .45's and .454's I've put through it, but there have been many... and none of them were light loads. (All handloads except one box of Hornady 300gr. 454's) Not a hitch yet, short of having to put a drop of LocTite on the ejector rod to keep it from backing off. It's a handful every time.
