H110 and w296 are similar. However H110 can be temperature sensitive. I prefer H110 over w296. My experience with H110 is a hotter primer makes for a more consistent ignition and burn . I use primarily winchester lpp for everything. I shoot h110 in my 41 mag and my 44 mags. When I switched to mag primers my groups shrunk noticeably in both guns .
