A week ago I posted that that I was able to pick up 5lbs of lead at camp from a snowbank that has melted away. The loads were all Lyman 358477 with 5grains of Unique in a 38 special cases lubed carnauba red. I get no leading in my Ruger Blackhawk. I have literarily put several thousand of these through this revolver as well as my 686. Now the puzzling thing in the photos I found 4 out of several hundred (all together i picked up 6.1 pounds) that have a hole in them. I can put a needle in around 3/16" more or less. I run a pro melt at 700 degrees. I am about positive that these blemishes are not getting by me during my casting / lubing process. I inspected the blemished ones they almost look like the area around the pin hole is melted however with such a light load and no sign of deformation around the base. I am puzzled. Of course this is the first time I've ever been able to pick up that many in tact cast boolits. The only thing I could come up with is a light spot in the lube allowing the gas to concentrate in one area. Thoughts anyone?
