Experimenting With Lee R.E.A.L Bullets
Rifling engraved at loading, sounds self explanatory but it was something that didn't occur to me at first reading. What it means is the soft lead cast bullet is cut by the rifling in the barrel. This requires a tight fit, with the bullet contacting the lands and grooves of the barrel with no patch or paper in between. Unfortunately, while researching R.E.A.L bullets no mention was made of use with paper cartridges, I see why. I cast .50 caliber 320 grain R.E.A.L bullets for my New Englander, filled the lube grooves with my own bullet lube, and followed my normal routine for making paper cartridges. The goal was to make loading easier, I didn't achieve that goal, loading was very, very difficult. One of the best things about the black powder community is being able to talk to people that have years of experience. It was suggested to me that, at least for round balls, paper would not be sufficient to provide a tight gas seal. What I discovered, my usual paper cartridge routine using a former and a powder loading block works, for round balls. I use a large cut of coffee filter paper, which allows me to wrap the former 3-4 times. That takes a .006 inch thick piece of filter paper to .024 thickness. With a .495 or .490 diameter round ball the total diameter becomes .519 for the .495 round ball and .514 for the .490 ball. That's overall a larger size than the rifle barrel but the ball and paper engages the rifling and provides a good seal. This was a theory, that I proved today.
