Back before RST and the Sherman Bell tests, Ross Seyfried wrote about using 7625 for low pressure reloads in damascus and twist barrels. He advised to do a thorough visual inspection for any flaws or alterations, then said to stuff a couple of Win AA loads in, rest the butt in an old tire on the ground, with the barrels lying on top, tie a string to the trigger, and back up about 50 feet and let her rip. The AA's, he said, developed only about 10,500 psi which was plenty enough proof for him. I tried it on an old pair of Ithaca twist barrels with pristine bores, and they "passed" the proof. Notice I didnt stuff 3 inch 1 7/8 oz 2's in it. Have fun!
