This post is for Bob Jurewicz who hasn't had any joy in trying for several months to gain access to this site.

"Read all the DGJ articles relating to use of Nitro for Black in early double rifle cartridges. I am reloading 450 BPE with 48 gr 4198, 300 gr cast bullet and 13gr of Dacron Filler. Sherman Bell tested this load using I believe cork wad as filler and got about 22,000 lbs. per sq. in of pressure. He promised future tests using dacron and has yet to publish those.
I believe that cramming 14gr of dacron in the unfilled case may reduce case volume and significantly increase pressure.
Is there anything out there on dacron vs Pressure????
If not what are the theories? I have read recommendations for anywhere from a couple of grans of dacron to a case stuffed with tight packed dacrom to fill the airspace.
I'll be interested to hear your ideas!
Bob Jurewicz"
