Like you, I returned to BP shooting a few years ago after a long break.
I started with 777 and I'm perfectly happy with it. Using it in an ROA, a Pedersoli LePage and a Uberti Colt that is so old it's almost an original!
Like BP, it takes a while to find the sweet spot of a load but I find it very consistent. Cleaning is a doodle which is also a MAJOR plus point for me and there's no faffing about with strange wooden boxes!
