Runball, Hi I am new here, and read on pg 1 that you pump parts of loads, using wads. That last thing you want is to pump charged breeches.
If the ram rod follows your hand up when loading, you can be certain the down stroke is creating compression.
Under the correct conditions, compression can raise temps high enough to set off the charge, and you won't like it much. This works the same way the compression fire starters work.
Chances are remote this will happen, but still the idea is valid, and it has happened.
I figure so long as you are aware, the choice is yours.
To ALL:
Often times these days cock angles are incorrect, which can smash flints on frizzens. It depends on the angles you have as to what must be done.
Sometimes you can heat the cock jaws, and bend them to be correct, and sometimes you can change the frizzen for one shaped with more or less curve.
I own a Nor West Gun as a kit from Curly, who is now hunting in the 'Happy Hunting Ground'. This gun did have to get a more curved frizzen.
Frizzens are fussy little buggers aren't they.
Lots of things can go wrong with these. They need to ride the spring, and cam over 2 ways smoothly.
It is pretty easy to cut right thru the case hard, but it isn't to hard to re-case harden them.
Another method which is interesting is you can forge out a hand file to be thin, and once shaped to fit the frizzen face you can make rivets and rivet the file face to the frizzen face, which was done way back then too.
Doing that can fix frizzens pretty well, and it creates an interesting look if the rivets are made of common nails and are counter bored, being filed flush.
With this method you can 'draw' the frizzen to be dead soft, which makes it more able to with stand shock, and still have a glass hard face for the flint to cut.
