[QUOTE="flashhole, post: 433048, member: 21375"] In general you want to use a magnum powder when you have a long powder column you want to ignite or if you have a powder that is difficult to ignite. Some will say it is better to have a magnum primer if you shoot in really cold climates, sort of like an insurance policy to guarantee ignition when you are sighted in on Buckzilla or any his Zilla cousins like elk and moose. I use magnum primers on my 7mm Rem Mag, and 300 Win Mag (before I sold it). I've tried them on my 45-70 and 25-06 and could not distinguish a difference from conventional primers so stopped using them in those cartridges. Not sure why you would get desirable results in a short case. I don't want my primer dislodging the bullet, I want the powder to do that job. In my 221 Fireball the milder primers give the best accuracy by a wide margin. [/QUOTE]
