They won't be too hard to shoot down the barrel. Zinc is softer then steel. The problem you will have is the mold won't fill out right, radical bullet weights, and probably not an even weight distribution around the axis of the bullet. I've heard that about 2% is the maximum you still don't want in a batch of lead, but castable. If possible keep it out. You can flux it out with sulfur, but I've never done it and its not very safe because it's toxic. If you smelt below 600F the zinc should float on top to be scooped off. Zinc I believe melts at 750.
