That information is not readily available from the manufacturers. The question is why not? We are to blindly accept their word without scientific data? Even if the info were available.....how would you set about using it without equipment that would tell you how your gun is working? Blindly accept data.......from the manufacturers? Yeah. Why not?

I have already decided that BH209 (a smokeless powder) is my next powder of choice, because it is simply the most economical thing for me to do.
I can use 84gr (weighed) or 110gr (volume) for 2129fps with a 250gr saboted Barnes TMZ. I will work up my load for accuracy and continue to weigh all my charges.
I would just like to see some actual scientific data. That way I can make an informed decision based on real data, and not just take it on someone's word for it. I have not been able to find any published data. The companies that should have it are just giving me the standard response of don't do it.

Or if you normalize to peak pressure something roughly on this order. ![[Linked Image]](http://venturecomm.net/~jongreen/norm.jpg)

You can take that up with Paco Kelly, his graph.

I just wanted to emphasize the difference in area under the curve as a general proposition.
