Hello all, can I have your oponions on the use of magnum primers in non magnum calibers, when loaded with slower burning powders.Thanks in advance.
magnum primers will burn hotter and increase pressures in non magnum cases so reduce loads by 10% and work up again. Personally i would only use a magnum primer in a magnum caseHello all, can I have your oponions on the use of magnum primers in non magnum calibers, when loaded with slower burning powders.Thanks in advance.

reduce load by 10% and work up with magnum primers.
i use magnum primers with
100gn spbt in 243
150gn spbt in 308
250gn spbt in 338
they burn hotter and longer so they burn most of your powder but do look out for presure signs.
yes you do end up with less powder and yes velocities are higher,you have to work the load up at .2 at a time and to watch for presure signs.
what cal are you loading?
