Does anyone know if a magnum large rifle primer can be used in place of a regular large rifle primer ?
And if so, does one need to adjust the powder charge any? I've read that with small rifle primers
there is no difference in charge from a regular primers to the magnum primers, just the cup is
thicker to handle the higher pressure so you don't get blown primers with higher pressure loads.
The reason I'm asking this is I'm about to run out of Alcan regular large rifle primers and have
a large amount of Alcan magnum large rifle primers to use. The rifle and load I'm using these in
is for my K-31 Swiss, current load is 41 grains of 4064. So I'd like to use these primers but am wondering if I need to decrease the powder charge if there is a bigger bang with magnum primers.
Thanks for the input
