OK! I've returned from some experimentation on Galvin's eqiupment, and I'm happy to report that I've had some good results using the 1/1 Nipple Cream/Petroleum Jelly combination. The result was a smooth, oily, pleasant smelling concoction that makes its way into every nook and cranny.
I'm using the Lee .452 Sizer Die. I applied the Nipple Jelly in a thin film on the sizing punch and the Hi-Tek Coated Boolits. Unlike last time, where I had used ZERO lube, counting on the coating to do the work, I ended up with leading.
However, Using the Nipple Jelly, almost all boolits made it out into the hopper unfazed, with very small chips flaking off of the boolits in the process.
Excited to try things out, I completed a small test. One with a Bonanza expanded Case (which can only expand after depriming, and the other using the Lee Expander. The results? The Lee Expander did a better job!
Only a small amount lead showed up in front of the case mouth and the bullet was seated nicely in a smooth motion, like it should have.
However, the extra-blunderbussed Bonanza expanded brass almost didn't fit in the seating die. I had to shove the brass through the seating die with way more force than anticipated and the result was a ring of about 60% of the case mouth covered by a little bit of lead.
Still, after pulling the two bullets, the near perfect Lee expanded boolit still had a small part of Hi-Tek shedded off.
However, the Bonanza bullet had the top band shaved off as usual with the poorer quality reloads from earlier.
I think I'm onto something, and hopefully, all I may need to do is tweak the seating a bit and I think this problem could be solved!
