The rounds with the medium loads were essentially the same. 1109 FPS for the magnum primer vs 1111 standard - within 0.2%. The range and standard deviation were also the same.

That's with Bullseye. The results might vary with another powder. But Neill and I both plan to use Bullseye for our 9mm, so I consider these primers to be a drop-in replacement.



So I bought the 7,000 primers. The guy had some other stuff for sale, and he sold me a carton full of self-defense ammo, 21 boxes, for $100. Mostly Hydra-Shoks and Black Talons. Half of it is 10mm, I guess I need to buy another gun now.
You must spread some Reputation around before giving it to scruff again.

You done good...
