I agree with Sieger, your loads are over max, and the 115 grain load is WAY over max!! I've loaded 8.8 grains of Blue Dot with a Hornady 115 grain bullet, and it produced about 1,350 fps out of a 4" barrel. It was a safe load, but rather abusive to the gun, and currently the max I load is 8.0 grains with a 115 grain bullet which doesn't beat the gun up as much and still produces 1,250 fps out of a 4" barrel. Even your 100 grain load, at that relatively short overall loaded length is over max and over reasonable pressure limits. I've loaded 100 grain bullets with heavy charges of Blue Dot, but only when loaded to a much longer overall length, which reduces pressures, and only to be fired in very strong, modern handguns. I wouldn't use the loads you listed in any handgun, let alone a vintage luger....
