I recently purchased some magnus lead bullets for .40, they are the 155gr RN. I am having trouble finding load data for this round and wanted to see if anyone had any experience with them. My Lee manual only lists Accurate #5, R Silhouette, Accurate #7, Ram ZIP Accurate #2, and True Blue. For the plated 155gr most listed are vihtavuori. I have unique, auto comp, tite group, longshot, sr-7625, wst, and blue dot on hand. Anyone have any data or help? I understand that you should stick with published load data but I'm sure there is something that will safely work. Also, if you don't think it is safe to use the powders I have on hand for this load please tell me why. Also my previous loads of 180 gr XTP's were cycling through my M&P well at 1.120" any longer and they started to FTF. Thanks!
