I have a Magma .430 die that scratches the bullet where the unplugged lube hole are. All 3 holes do it and collect lead and clog up. It never did this before. Looking into the barrel of the die it appears smooth and polished. Can it be polished easily with something, or should I just chuck it into the trash and buy a new one? Pictures won't help as it looks perfect inside. The scratches are made on soft lead or linotype. Thanks, Rod
