Re: Small pistol primers vs small pistol MAGNUMS
I load with both SP and SP mag primers. When I work up a load I use a chronograph to get the powder charge to where it needs to be. Then I try both SP and SP mag primers to see which delivers the lowest standard of deviation. Some powders like standard primers and some work better with mag primers. The difference between the two makes very little difference in the velocity.
