ithaca1,
If you decide to use Kutter's great suggestion, I suggest further that you stuff a small plug (ball) of 0000 steel wool into the barrels to act as a dam to precisely locate the Cerrosafe where you want it. If you want a specific weight, you can weigh it before melting and either add or subtract pieces, it will weigh the same after cooling. Pay close attention to the instructions and don't move the gun until it has gone through the shrinking and expanding phases. Otherwise the weight may move to the wrong place. BTW, I agree with the others about the quality of Kutter's suggestions.
Mike
