    Load
    CALIBER: 44 Mag CASE:RP
    BULLET TYPE: RMR RNFP BULLET WEIGHT:240 Gr. Plated
    POWDER TYPE:Alliant Unique POWDER WEIGHT: 9grains
    PRIMER TYPE:CCI Lrg Mag SEATING DEPTH: 1.585

    I've shot a few hundred of these and they have been doing quite well. On my recent range trip I was shooting five shot strings really dialing in my red dot. All were shot single action hammer cocked.
    On the fifth run of five shots, in the fourth shot I felt something hang up the cylinder. I stopped and opened the cylinder. Between the back of the brass and the rear of the gun, think between primer and firing pin area, was a piece of shaved copper lead . I was on the end of my time limit sp I packed up, stuck the lead remnant on the load sheet sticker for later review.

    When I was home I inspected everything. No signs of anything abnormal. The four spent cases and fifth unfired looked normal. The five before that string all looked normal. Cleaned gun. No signs of leading at all. No abnormal fouling anywhere. Checked timing by simply slowly pulling hammer back and confirming cylinder locked prior to hammer set and checked all six positions. Able to run my bore light down barrel and see around it, no visible out of time noticed. (I'm no gunsmith) put light resistance on cylinder to see if the hand that rotates cylinder would slip, all felt good. Inspected part on shell extractor that hand rotates and looks to be in good shape.

    Only thing I can think is that some shaving happened as the bullet passed the forcing cone. With that said it doesn't clarify finding it on the back rearward side of the cylinder. In contemplation I surmised it may have happened the string prior and upon reload was allowed to fall into that area.

    Attached is the small shaving and my previous five shot string at 50 feet. Those are 1" grid lines.

    Thoughts? Over thinking it? Seen it, no big deal?

    Either you shaved that seating a bullet, or the forcing cone shaved it because a chamber wasn't lined up well enough.

    Or you could have over crimped. Using a roll crimp on plated bullets? It's not hard to overdo a roll crimp on plated, especially if case lengths vary.

    I'm in agreement. I hand check every load with a dillon case guage so I think, assume, should.. have caught it if it was shaved as the guage should have caught it.

    If that thinking is correct then the next question is more important. Perhaps there is a timing issue that my untrained eye doesn't perceive

    Edit, since you replied again. Over crimp. Good thinking. I'll do more digging on that. Still have about 45 unfired from that box

    It had to be just sticking on one of the rounds you were loading in the chamber and fell where you found it. I can't imagine the forcing cone could have shaved it flew out sideways, then it flew backwards, then sideways again.
    Walkalong has to be right that it was stuck on one of the bullets you loaded and fell off on the back of the cylinder, loading the cylinder, or the edge of the cylinder scraped it off and it fell, or stuck where you found it.

    One other slim possibility - it may not even be from your loads. Shooting at a public range, I have been hit by a fragment like that, from the guy in the lane next to me.

    Possible yes, in my case I was in an indoor range with bulletproof glass between bays. I like the brainstorm though.
