Magnum small pistol primer and 9mm...
Some of you may remember I am a newer to reloading. I haven't been able to source primers. Well today is was able to get 300 large rifle, 3,000 small rifle and 1,000 magnum small pistol primers.
Now to the question....what should I know about substituting magnums for standards? I plan to load starting with minimum recommended powder, Universal Clays.
Or is this something that you would avoid all together?
