Was able to purchase 1000 CCI 209M Magnum shotshell primers for $50. Couldn't pass up.
Question: How much more "oomph" do the 209M primers have over standard 209's?
Hodgdon recommends 209M for 30-34 grains of Longshot pushing 1-1/8 oz shot to >1400 fps. I don't need that kind of velocity.
If I use a 209M to ignite a low-power 7/8-oz Cowboy action load of Clays; or a standard 21-gr load of Unique pushing 1-1/8 oz shot, do Magnum shot primers cause problems?
