Looking at a few books for loads, I find it interesting that Hornadys 6th Edition doesn't show Titegroup as a powder, although in the 8th Edition it shows a start of 4.5gr to a max. of 5.6gr. with fps 850-1000 respectively. Lees second edition list nothing for rifles in general, however they do have lists for 45LC, Ruger and T/C, they list powders I don't have, upon further research I found Lymans 49th Edition shows a recipe using Titegroup for a 255 gr. cast with a starting load of 5.6 gr to a max of 6.2 grs with FPS ranging from 816 to 896, the same info shows up in Lymans 3rd Edition of Pistol & Revolver Handbook, I assume this is for a pistol only and not a rifle. I have to ask though, Will the .454 diameter bullet have issues going through a .452 bore? I have read that reloaders do want a cast bullet a thou or two oversize for a good seal. Of the two Hornady & Lyman where would you start since Hornadys max is a starting point for Lyman? Mr fixit
