I don't use too many gaschecks - mostly I shoot handguns with loads at moderate velocities and PB boolits work fine - so I don't have a lot of experience with them.
I am working on another project which needs a gascheck-like seal to operate and I was going to try and use some 0.002" thick 309 stainless steel "high temperature tool wrap" that I have. The seal will not move so friction/wear from velocity is not a problem in this application.
Made me wonder if there is any use for this material as a gas check for cast boolits. I'm principally concerned about barrel wear. The material is an austenitic grade of SS with 22-24% Cr, 12% Ni and C<.2%. It can be annealed at 1800 to 2000F and I have access to a furnace that can reach those temps.
Main attraction is cost. Bought a 50 ft x 20 inch roll from Enco for less than $150 - enough to make 24,00 .45 caliber gcs at a cost of $0.00625 per gc.
Anybody have any opinions/experience with this stuff?
