OK today I had my first casting experience. Started out a little shaky, but after the mold got hot enough, it started filling the cavities pretty well. I used a 1-1 ratio of soft lead and WWs, with a little 95/5 solder in the mix. The ones I let air cool had a BHN of 10.4. The ones I water quenched was BHN 15.4. Took a little time getting used to the Lee 20X microscope, but final steadied it enough to get a good reading. The Lee mold 429-200 was actually dropping them at 210 grs. Some of them appear to have both halves not matching up very well. Didn't notice it until after I was done. Upon inspection of my Lee 2 cavity mold, it looks like each side doesn't always align properly when closed. Yet I can take my fingers a force them to align perfectly. Is there some sort of adjustment required? I also noticed that even the ones that appear to be seamless, are not actually round. My calipers measure one at .430-434 size, and some seem to be 429-434. Any thoughts and/or criticisms are appreciated.
