Are there any charts on B.P. Cartidge Camber Pressure's?

Howdy, Pards,
.........I DO have pressure-time curves taken on a .45-70 rifle using the Oehler M43 Personal Ballistics Lab, showing the curves of both Remington factory data and my own loads using cast bullets.  The smokeless powder P-T curves are much more gentle than produced by the 18 gr. charge shown on the other post.

pulp, DJ,
Not true for all smokeless. Remember:

That's all I have to say on the subject because Cuts Crooked has made it clear that this board is for the discussion on b.p..http://www.cascity.com/forumhall/index.php/topic,20410.0.html

I'd like to see pressures for the 44-40 and various BPs

It would be nice to have one of those Oehler strain gauges, or access to some testing facility.

W44WCF,
The Topic was about B.P. Chamber Pressure. And the intent was to get a idea of wheter a certain action was strong enough to shoot 32-40. I had no intent to anything wrong, and I don't see that I did. I have ben reloading for 30 years all smokeless, and that is the reason I ask about Black Powder Chamber Pressure. There just doesn't seem to be much Data out there for Black Powder. I have seen several action on the net that have blowed up, and something had to cause the problem, so I was trying to get info on how and what effects chamber pressure with Black Powder. The reply's have been a great help to me, and I thank everyone for there input.
Later
