I'll be dam he mention that shot column height came change pressure in the shell.

Think I'll sell my bowling equipment and go back to reloading.

Of course it can change the pressure -- it could go up if the the column consists of lead -- you increase the height of the lead, you also increase the weight. It could also go down if, like in my example, you used rice instead of lead -- a load of rice could be twice as tall as a load of lead and the pressure will go down because the weight of the load of rice is less. But you said: "a taller or "longer" load column will increase pressure every time" -- it's the EVERY TIME that makes your statement wrong. A taller or longer load column doesn't increase pressure every time.

The nice thing about bowling is that you don't have to know how to read. It's a great sport that way.

I take it you do alot bowling.


Yes , when using the same weight of different shot types . Everything else in the load being the same pressure will change . Sometimes alot. Doing that is a guessing game, a chance I'm not willing to take without test data .


Carry on with out me.

Yes, I remember those pics, Ron. I have the entire series, and need to get them out and reread them all this winter to refresh my memory. I had some correspondence back then with Bell, by letter, and he always impressed me as being both thorough and courteous. I should reread those letters at the same time.

Best, SRH

My example of using bismuth in lead data published data 22.5 gr 800x 1oz shot AA hull w209 p 1215 FPS 6500 Lup. Load number 2 22.5 800x 1 1/8 oz shot waa12 wad 1200fps 7100 lup I put 1 oz bismuth in the 2 nd load the waa 12 wad accommodates the 15 percent increase in volume which is about 9 pellets the crimp is perfect. I may be playing with danger ,I have been shooting this load for decades , very soft recoil. Disclaimer this is my personal load and I certainly do not suggest that anyone uses this data . Just adding to the mix . Thanks don
