I've only run my new RCBS Pro-Melt 2 a few times. The PID is right on at 700 deg when compared to my new RCBS lead thermometer, which was my target temp. Outside temp was about 34 deg. Once I got my molds up to temp I had a hard time trying to figure out what method was the best to get a clean pour. My nipple had a leak so after awhile it would create at little spire of lead and it would get in the way of sliding the mold block forward and back when sitting on the Mold Guide. I dispensed with using the Mold Guide. It seemed if I did single pours into each cavity it "might" get a clean bullet but if I tried to run a continuous stream of lead the lead would fill the current cavity and before I could slide the next cavity under the lead stream, it would overflow into the next cavity. This would get a partial fill, which would freeze, before I could get the lead stream directly into the next cavity.
1. Continuous stream or pour/stop/move...pour/stop/move, etc.?
2. I run LBT molds with their "continuous" sprue trough so should I keep the nipple super close to the sprue plate or lower the block 1/4", 1/2" , 3/4" below the trough?
3. I was trying to follow Rick Kelter's/LASC suggestions of keeping my temp to 700 deg. Should I run a bit hotter?
I was running a 4 cavity, 44 Special, 255 gr and a 2 cavity, 480 Ruger, 390 gr.
