You did make one fundamental mistake,,,
You should have bought two.
A long time ago in a galaxy far far away,,,
I purchased a pair of single shot cap and ball pistols at a garage sale.
My ex wife and I had a blast shooting those dang things,,,
There was something very pleasant about the shared ritual of charge, load, prime, & shoot.
An entire afternoon of shooting for less than a $20.00 bill,,,
And the cleanup was quick and easy.
I did find it amusing that after a while,,,
We both thought it would be a great idea to buy two C&B revolvers,,,
That turned out to be not such a good idea as we both thought it would be.
The revolvers were not nearly as much fun for us as the single shots were,,,
The whole leisurely aspect was defeated by the revolver's complexity,,,
It simply wasn't as much fun as with our single shots.
As for specific advice on completing the kits,,,
Take your time and work on the finer details until they are right.
Then go and have some fun.
