3 dram & 3 1/4 dram
I have a 1924 DHE 2 barrel set, 28 inch and 30 inch barrels with the original hanging tags that show what the barrels were proofed/test with. the 28's show a 3 dram load and the 30's show a 3 1/4 dram shell tested. Is it safe to say that I can shoot modern 3 & 3 1/4 dram?? Or have the standards for dram equivalent changed with modern loads?
