Thanks a stack for running it through your program, this helps me a lot! I unfortunately do not have a chronograph, but I am able to use one at our local gun range. I will try starting at around 74 grains and work my way up from there.Pietro, I have a software program called QuickLoad. With it I can "simulate" what might be expected from using different types of powders, bullets and respective weights. I just did a workup for a 458 Lott (with a 24" barrel" using the Peregrine 500 Gr. VRG3 and RL15. It shows a MAX load of 79.3 Gr. producing 2284 FPS. Start with loads lower than that and work up depending on pressure signs. BTW do you have a Chronograph? Hopefully others that actually use the components you named will be able to give you actual rather than theoretical information.

Hi Shootist43, I have finally received my license for the 458Lott. I have loaded 74 grains of RL 15 with the 500grain Peregrine VRG3's and will be at the range on Thursday. Will report back as soon as I have the results. Thanks again!Pietro, I have a software program called QuickLoad.
