I revisited the post and, for some reason, the adds weren't as bad.
When I got home yesterday evening, I tried to make a few of these paper cartridges. My gun is .54 so I used a 1/2" dowel that I had. I started with a thin paper bag. I am only using a 55 grain measure of #6 shot. It ended up about 1 1/8 long, not including the fold and twist, and fit into the muzzle easily.
Then I tried a thicker paper bag and it certainly made a more durable cartridge, but was a bit snug in the muzzle.
I suppose the overpowder cards and chunk of sisal will hold the cartridge in place (while loading with the muzzle pointing upwards) until you cut/ tear the twisted end off. Is this true?
If I use the thinner paper, I think I can leave the dowel as is. If the thicker paper is better, I'll need to shave a little off of the dowel.
Do you have an opinion as to which is better?
I don't have everything I need to fire this in my gun. I need to get the wads/ sisal in order to complete this set-up. I'm really looking forward to trying it.
Being able to ram all of this down at one time and especially not having to cut slots in the overpowder cards to let air escape is very appealing.
