I have used the Javelina or 50/50 mix of Alox and Beeswax for my cast bullets since 1973. I've tried others. Never tried the LBT blue. I might do that one day, but I shoot a lot more rifle cast bullets than Pistols these days. I just checked my database and I shot over 2,000 cast bullets last year in my rifles and Thompson Contenders.
Here is the kicker. I shoot medium soft bullets up to 2400 fps and most of the time at 2,004 fps (chrono-graphed velocities). Bullets are gas checked.
No leading at all and I rarely clean the barrels. It is a cardinal rule in my shooting group (most of them learned the hard way) that You don't clean a cast bullet barrel until the accuracy fails.
I have cleaned my Rem 742 30-06 barrel twice in the past 3700 rounds and it is still shooting 1" cast bullet groups at 2,000 fps. The first cleaning was at 1400 rounds. I know, you all have heard that those rifles don't shoot well. A dinner plate at 50 yards is the best it will do. I've heard that too.
My theory is that I'm afraid to change something that works and has worked for 35 years without fail. I don't want to reinvent the wheel. I started a database in 2000. Since that year, I have fired 47,173 cast bullets with 50/50 alox lube. No leading, boys and girls. When I first tried cast bullets in rifles, I used bullets from a friend and his suggested load. It took 8 hours to clean my Sako 308 barrel. I didn't care much for that idea.
When I size the bullet, I kick it out with a finger into a box in a drawer below with a downward slanting bottom. I keep an old soft cloth containing Motor Mica dusting to cover the box bottom. The bullet rolls down the slant, picks up the motor mica and it is not sticky. I finish a couple hundred, hold the cloth closed and roll the lubed bullets around in the cloth. If a loader person is looking for a thing of beauty, this is not it, but they work.
I have used the same method with handgun bullets in gross quantities with my whole family shooting weekly. I'm glad those kids grew up and left the nest.
I followed the advise of an old reloader that was in the business of ammo manufacturing. I'm afraid to change. Do I know if it is the motor mica that helps keep the slick surface from leading. I don't know and don't want to find out the hard way.
I get to laughing at us old farts. We all have different experiences and that is what makes it interesting.
