I already have lots of straight clip on wheel weight ingots. "No" stick on or other soft lead mixed in with it. I also have lots of "50-50" clip on wheel weight and stick on alloyed together. I have been gifted lots of type letters. I believe them to be linotype. I do have some of the spacers with the holes running the length of them. My question is how do I go about adding this to the pot to add the tin? X lbs of ingots to Y lbs of my type metal? Any direction would be helpful. The boolits I now cast shoot wonderfully. The edges are just not as crisp as they could be.
