I just finished casting some 358156HPs. Not quite as bad as I thought. I took my original alloy 50% pure Lead and 50% linotype and cut it with 50% lead thinking this would soften up the allow so that the HP would expand. I haven't shot any yet so we will see if the theory holds out. I did discover a helpful hint when using a pin. After filling the mold, I cut the sprue, remove the pin, set the pin on the rim of my furnace and drop the bullet. This seems to keep the pin hot enough to prevent problems from the pin becomming cool. yesterday I cast some 41027 (.41 hollow base wadcutter) using a pin Buckshot made for me. It works perfectly. This is one neet looking bullet. Can't wait to try it out. What would you fellows suggest as a test medium for the HP bullets? wet newspapers, Phone books, or a hunk of modeling clay? Any suggestions would be appreciated. After the test, I will try and post some photos. I will have to borrow my daughters digital camera. What a bummer. Both of my children have one and I dont. Of course, they dont have all the neet shooting toys either.
