I completely respect that GB. I should have been more carefull with my question. I don't want any loads that are hotter than published loads, I have a lack of data at this time so I came here.I wanted high end ruger loads. I learned a bunch from the replies though. I understood almost everything, h110 was for hot loads, but I included other powders in the question for reduced 454 stuff. I know you cant reduce h110 more than 3%. I had planned on using bonded bullets in 185 grain for increased speed, hopefully resulting in flatter trajectory, for deer hunting. everybody here says thats a no-no, and I listen to experience, so whats the best way to get a flatter trajectory? (besides knowing your load and its limits) are 454 bullets thicker jacketed in general? I had thought that some of the xtp's for example were fine for 45 & 454? Also, at under 2000 fps I don't understand how barrels could wear out quickly? How do you know if you have the correct bullet shape & speed for the forcing cone of you revolver besides looking at load data, and what happens if you don't? Lots of question, and now they are in the wrong forum, but I do need to know this stuff, I certainly dont want to wreck my guns or get myself or other hurt. Thanks guys.
