I have a .41GNR on a Blackhawk. I opted for another cylinder rather than opening up the original - and I'm glad I did. A couple reasons for this, first of all I still love the original Mag chambering & second, the cylinder done by Gary is just so darn good looking! Great bluing & ".41 GNR" lightly engraved around the cylinder.
I've mostly stuck with his recommended loading with Sierra 170's and indeed have found them to be flat shooting, good performing. I've also loaded some 210's and found them to be a bit more accurate overall, but not by much.
I know some fellers have loaded 250 & heavier cast, but I've not done so yet - I'd love to hear from them as well.
I had Gary do some other work...Maxi throat, action job, Bisley hammer, fit grips & Belt Mtn base pin. Very pleased with the results. There is more info on the .41 GNR round at
www.cartridgeperformance.com This is a friend of Gary's that is making "factory" loads for several of Reeder's wildcats, though reloading is a cinch.
I know there are others on-site who have much more experience than I do on the round, but that's my two-cents.
