I am considering buying Quickload. I am wondering if it will work for my situation any better than my homemade Powley calculator? My situation: I am shooting a smokeless muzzleloader with custom sabots. I basically have a straight walled case of nearly unlimited capacity ( within reason ). There is no throat so there also is no swaging of the bullet into the grooves making pressure somewhat problematic. My bore is a 0.450/0.458 Shilen barrel 23 1/2 inches long; My bullets are 250 grain 0.338 Accubonds; My sabots weigh 25 grains. My goal is 2800 - 3000 fps. I prefer to keep the pressure not much over 50,000 psi. My homemade calculator only yields IMR powders and suggests 100 grains of IMR 4064 should get me to 2900 fps @ under 50Kpsi. I don't have this powder and would prefer to use a Hodgdon powder but I can't correlate powders with my calculator. I guess my question is do you think that Quickload would work for this type of a situation, and is it worth the $150 price tag? Thanks for any suggestions. edge.
