Last month I finally bought myself a little something. Wanted 45 thump without the 45-70 powder consumption. After several months of pondering & searching for barrel length & twist rate, along with as much load data as I could find (which ain't much). I settled on a Browning 1885 in 454 casull, 28" octagon barrel with a 1:24 twist rate. I was worried it would be excessively heavy. But even after mounting a Leupy 2-7 scope on it it's not near as bad as I had expected. And then the adventure began trying to locate Dies, Brass, & etc to get everything happening. And finally started powder coating, It has been a blast. I almost feel wasteful shooting it as scarce as everything is.
