Primers

[desert deuce]

Interesting.

Don,
Is your answer based on actual shots fired over a chronograph? Or do you, like me, base your conclusions on groups fired on the target?
This is something that I never gave a great deal of thought to in my former life as a high power shooter. It was Federal 210M’s, a good bullet and the appropriate powder, and good things would happen if you could hold hard! Now I’m told that SD should be between 5 and 10 and the key to this is the right primer.

Arnie,
I’ve heard good things about Federal 150’s. Unfortunately I don’t have any at this time.
I’ve tried other pistol primers in the past but didn’t see any difference. No chronograph tests though.
But what’s the deal with large pistol primers contributing to damage to the face of the breech block?
I just have a hard time wrapping my head around that!
