Hello, just ordered a 460 barrel for my TC Encore and I cast a 260 grain bullet from a NOE mold. I need another for the 454 and 460. Not sure what these single shots may like. I’ll just use the mold from Al for the 45 and it may be ok for 454 not sure. I’m using Rcbs cowboy dies for the 45 colt since it had 2 expanders it kept me from buying an M die. Stick with another set of Rcbs for other 2 calibers or something else you would recommend.
