Here is what I remember from my 454 Encore. Sorry, I destroyed the load data a while back so that I didn't get it confused with my Ruger SRH data. Mine was a 12". I find that 10-12" about right for myself. I would opt for that length range, since I believe that a 15" might really be hard to control with that quick snap.
what load do you people use out of yours?I used a Hornady 300 grain XTP with a near max load of W296 for hunting. Titegroup also did some good things for less tha max loads.
will this barrel need a 6 hole scope base?I had a standard 4 hole base on mine. I used 3 rings on a Leupold 4X scope. The rings were Warne. I don't know if I needed the 3rd ring, but I felt better doing it.
How bad will it kick with full power loads? It will not have a breakIt definitely got your attention with the 296 loads, but wasn't bad once you get the feel for it. I noticed it more at the bench.
does yours shot well with cast bullets?Never used them in the Encore or my SRH.
how does it shoot 45 long colt?Never shot them in the Encore, since I could load the 454 down enough to be in the ballpark of the 45 LC.
