    I am shooting an MX-8, bought used but excellent and I really like it. I have probably shot about 2500 rds. in 6 months, on top of the possibly 5k to 8k in its previous life.

    Ok, so here's the problem:

    I was cleaning it last night and I noticed a definite furrowing or groove starting to wear in the breech face below the bottom firing pin hole. It becomes really pronounced on the bottom lip of the hole, almost a dishing effect. I believe it is caused by the fired shell brass rubbing hard against the breech during the ejection cycle. The ejector pressure is pushing the brass hard and there is a shallow but noticable trench starting to form.

    This might be from using steel headed shells like Estates which I have been shooting a lot. I would call this a "premature aging" of the gun, and I don't like it one bit. At the rate this is going my gun will be pretty ugly by this time next year.

    Is this normal? Is it something I need to talk to a service department like Giacomo's about?

    I sent the question to Bruce Buck, The Technoid. Maybe he will have an idea of what I'm talking about.

    Is this a Ithaca or Winchester Import?

    I have an Ithaca MX-8 that has in excess of 50,000 shells shot through it and have never experienced this problem.

    Mostly Winchester AA's and reloads using AA cases have been shot through my gun.
