Tried casting from the 32 cal - 98 grain swc double cavity mold -accurate 313-100 r rg mold - I bought from a member before hot weather hit. Had two, two pound ingots, and assorted sprue casts, etc. Trying for a 20 part lead to 1 part tin alloy. Heated it up in my Lee 10# pot, fluxed, had a run of about 70 bullets, there were striations and bad wrinkles. Tried again that afternoon; same result, then just cast into the SEACO ingot pan. Looked like lava again. Finally figured out the spout was half stopped up so the trickle was so slow as to cause the lava flow aspect. Sunday I took the Lee production pot apart. Managed to free up the flow plug after I unscrewed the connectors on the top. Then cleared up the upper part of the spout. Then turned it upside down and kept tapping with a small allen wrench until it was clear. Note: before that I tried using the propane torch to melt what was stuck in the spout but it must have been slag with a higher melting point than lead, as it would not melt. So tapping it out was only option. Finally ran a good run on Monday, and began to get better less wrinkled bullets. Tried a second run, after dumping all prior castings, along with one lead ingot, after fluxing it all. And, at a higher temperature to where the lead on top of the sprue was frosting a bit. At that point the bullets began to be normal in appearance.
Learned 1. Need a good flow from the spot; a trickle will not do it, otherwise bullets look like stalagmites all layered over, and 2. Get the temp hot enough to frost the sprue puddle, but not enough to really frost the bullets.
Then learned to lube them with Lee Liquid Alox. Tumbled them with a 50% Lee Liquid Alox 50% mineral spirit mixture suggested by a member. It worked out. Then last weekend I loaded about 30 of the best ones in 32 S&W Long cases on top of 2 grains of Bullseye, and then shot a few out of my S&W Model 631 4". So this is a milestone for me. First cast boolit reloads that are good enough to shoot in my 32's. And a picture of the boolit and one of my new cast boolit loads. I am quite proud of myself. It took a spell.
