Should I be using magnum pistol or large pistol primers when loading .44 Mag with H110? My first rounds I shot were with primed Winchester brass that I’m assuming had WLP primers in them and it shot 23.5 grains of H110 behind a 240 grain XTP with no issues. My question is now that I’m loading again, can I use the same load with large magnum pistol primers? I’ve heard mixed reviews on this topic
Yes, H-110 requires a magnum primer. WLP primers are rated for magnum use. My .44 Mag JSP load is 24 grains of H-110. With a 4.25 " barrel, this gives me 1199 FPS.
