So, we tried the paper cartridge route and found a few things. One, the paper cartridge LAGS made with the standard ball was easy to load and accurate. Pardon that the target pics look terrible - they were done with cell phone from the firing line at the steel 50 yards away, so the zoom makes things look terrible.
This rifle just looks good no matter which way you look at it.
Here is the 54 caliber ball with 60 grains of home made powder.
Then I went to paper cartridges with the Lee Minie ball. First, I had a selection made from various tubes. What I found was - everything was VERY tight, so the paper is far too thick. The thinnest brown paper was the easiest, but a lot of the wax lube broke loose. I still got some decent accuracy, but loading was REALLY hard, as in having to use the hammer on the ram rod all the way down.
I had to share bench time with my loving wife who really needed some stress relief and my own J-word rifle that was doing its own load development. But we did get a few rounds downrange.
What I think is that a thinner paper might be far better, but the whole concept of the paper cartridge was REALLY easy and fun. The Boy enjoyed the heck out it, to be honest, got more shots down range in a shorter time, as one would expect.
And the world turns still...
