John,
Test it yourself and let us know the results! Follow the simple directions from my previous post. Load identical hulls and primers in loads at low psi and high psi. Shoot in the same barrel and examine the primers. If however you use very hard primers such as Remingtons the flattening may be less or not evident. The Cheddites which I use easily flatten. Mark |

Mark - I agree with that "Test", however, that doesn't answer my question whether or not hard shot causes high pressures. Can you say that hard shot has caused flat primers?
BTW, a friend of mine - a major league engineer for the big three, and a national caliber hot rodder, works up his high velocity rifle loads until he needs to use a mallet to open the bolt. Needless to say, I don't shoot on the bench next to him! |

John,
Hard shot contributes to higher pressure. Before I noticed the 1500 PSI increase notice on the Nice Shot website I spied that my 7000 psi Nice Shot loads were slightly flattening the primers. That made me think... It wasn't long afterward that a fellow web-poster referred me to the Nice Shot warning. I also recall recently reading something to this effect in an old shotgun book. I do remember that Askins wrote in The American Shotgun that 30% of the pellets are deformed upon firing. That book was published in 1921. Mark |

I'm not doubting your experience, but I'm calling BS on the good Colonel. Howinell could he ever back up that statement?
I am a proponent of slow-burning powders as a means of reducing peak pressure, and the resulting "Poke" it generates. I do believe that more gentle "Push" results in fewer deformed pellets |

It didn't work for me in 12ga- believe it was because the thin brass allowed more volume. I went up about half again [ 20 to 30grs] and still got bloppers. Seeing how I've already blown up one gun I quit trying. Paul
