It is disconcerting how primers and powder are so scarce. Perhaps the companies that make those things are assuming perpetual war is where the profit is. I wonder what the governments are paying?

I am attaching results of ballistic testing I had done by Precision reloading. All test loads were 20-gauge, 2.5-inch shells using Cheddite hulls and Cheddite primers. Powders used were WSF and Longshot. Some were 7/8 ounce (382 grains) and some 3/4 ounce (328 grains) of lead shot. All of the wads were obtained from BPI, and all shells were roll crimped, except the batch of shells I had obtained from Polywad, which were fold crimped. Some of these loads gave pressures in the range you indicated.

Playing Hooky,
Can't see the attachments

Ithaca1, they can be viewed by using copy and paste to put them in your browser's address window and then hitting "enter" key. I'm sorry but I haven't been able to figure out how to include attachments or links in my posts on this site. I am all ears if you can tell me how. If you can't see them by the above method, I think I can send them to you by email if you PM me with it.

Sorry for all my fumbling around trying to attach the results of pressure testing of 20 gauge loads, some of which gave low pressures in the range you indicated. Hope this link to email containing the two PDF files is accessible.
