    Chamfering the chamber

    Red follower: a JM made 1895 SBL
    Black follower: a JM made 1895 SS (made in 1990)

    If you cycle the 1895 SS too fast, the bullet of the round can hang up at the top of the receiver. (if using conical bullets)
    For the 1895 SBL, you can cycle as fast as you want.

    I will post photos of the chamfering process the next time. (No time and not the suitable tool at the moment)

    Ok, so here's how it's done:

    Just to show a bit more detailed what's my issue, here some photos:

    If you use conical bullets, or (flat) bullets with a big diameter tip, and cycle the gun very fast, it can happen, that the bullet hangs up at the top of the receiver. To be more precise, at the rim of the chamber. To this point of time, I had not had the issue when I was using bullets with a round tip.

    Tools and things you need:
    A grinding pen (cone shaped -the better choice I guess- or ogival shaped, shank 3mm is ideal, but 6mm will do also I guess), a small diameter pipe (inner diamter = outer diameter of the shank), some glue (I recommend epoxy) and another small tube, piece of metal, a stick,and an electric drill.

    Take about 8 Inches of the small diamter pipe an glue the pen in it.

    The tube has to be long enough, you can put it in your drill and through the whole receiver to the chamber

    So what's the small pipe / piece of wood good for?
    It's for making a little helper for guiding the elongated pen:
    If you run this pen without any guidance in your gun, it will go anywhere and do anything, exept what you want it to do.
    File a notch into one end, so the shank (the small pipe of your pen) fits into it.
    So after inserting your pen into the gun, you can put the Guide over it to control force and location.

    I higly recommend to grind very careful.
    Do some turns with your electric drill, and watch the result.
    If you grind not enough, you can do some more.
    If you grind too much, you cannot reload your brass. Or maybe you need a new barrel...

    Some photos:

    In my first test, I had no more problems fast cycling rounds with conical bullets.
    So I guess this shoud be the final solution.

    I will do some more testing and post the result.

    The whole story took about half an hour in total.
