Barrel… not lead, then what could it be?

    This is an AMT Hardballer barrel. At first glance I thought it was lead in the barrel…Then I realized it was only in the rifling lands/hills, nothing in the grooves/valleys….. very strange. Well, I tried to get rid of the lead but couldn’t. Bronze brush, pod cleaning scrub pad, Lewis Lead removal (just the fabric, around cleaning brush) with some Hopes 9… even 1000 grit sandpaper.. Nothing. I was very gentle when trying to remove, as this is a friend’s barrel, not mine. I even tried a dentist pick ..nada.

    I then took pics for closer inspection and realized this was not lead in the lands. I believe it is abrasion. Appreciate your comments.

    Looks like chatter marks from the tooling when the rifling was cut.

    Tool marks from the rifling bit...that barrel is as clean as a barrel can get in one cleaning.

    Tool marks. They seem to have caused an uneven surface/height in the rifling lands. Could these cause any problems with accuracy? Other problems?

    Agreed, looks like tooling.
    And really good pictures!

    Looks like the barrel was cut out of meteorite.

    That barrel doesn't surprise me. I worked on a friend's Hardballer and the inside of the gun looked as if it had absolutely nothing done in the way of hand fitting or polishing. Could say the same thing about all the internal parts as well.

    I had the hardest time fitting the mainspring til I found that the notch in the frame which holds the mainspring tab in place wasn't cut properly, preventing the mainspring from staying in position when the grip safety and mainspring housing were reassembled. All in all a very poorly built gun.

    I would throw that barrel in the garbage personally. But if it shoots okay... *shrugs*

    I imagine lead pills would fill up those gouges almost instantly and be a giant nightmare to clean. But that's just speculation on my part. Maybe FMJ would be okay on some level... Does he shoot it?

    Previous owner shot it, but I do not know him and don't have any related information.

    Unfortunately, AMT is not known for quality.. Hence, why they are no longer.

    How's the accuracy? My old Govt. model was a steaming pile, as far as dependability goes-you all know that by now certainly, but it's accuracy, when it worked, was pretty darn good.

    Seems like a fairly new barrel. Shouldn’t that buff out after a few hundred rounds through?

    Very cool pics by the way. Reminds me of James Bond 007.

    The only way to "buff" those out would be to make a smooth bore .46 caliber barrel out of it.

    Really outstanding pictures. I had a very difficult time taking pictures inside a friends' 1911 barrel. The camera would focus on everything but the desired spot.

    You know, your friend should just go out and shoot the thing. If it functions and groups well, that is all that matters. Given it is an AMT Hardball, those things were not target pistols, four to six inch groups at 25 yards are probably acceptable. What would be more important than target accuracy is, 1) does the gun go bang each trigger pull, and 2) is there a general relationship between point of aim and point of impact?

    I would not attempt any more abrasives or anything to "smooth" that out. All attempts in that direction are going to enlarge the bore and make that barrel less accurate.

    The barrel appears to have been drilled but not reamed or lapped, or reamed very haphazardly. That's the tops of the lands of course. After drilling then the broach (It looks like a broached bore to me perhaps), left the tops as they were.

    The grooves are smooth as you would expect from a broach under those conditions. A two stage button would burnish the tops unless the bore started out too big, and that's possible too perhaps.

    You could fit a match barrel, if the gun has personal value, or if the value is just an old gun like any other, and it's reliable, keep it as a bedside gun.

    The careful fitting of 1911's built now was not common when AMT made those, my GS remarked on seeing a new Dan Wesson "They are making 1911's better than ever now". I believe all builders quality standards have risen since the 80's.

    Any manufacturer that would select a process and tooling that would result in a garbage barrel like that deserves AMT's fate.

    Its just not that hard to do things the right way. But some organizations will never learn.

    My friend is not happy with this barrel and will sell the gun, in anticipation to the possible finding of more "unpleasant surprises" which would confirm Harballers sad reputation.

    Those lands should file nice, clean rifling grooves in your projectiles - there may be a yet unknown advantage to chatter like that - requires more thought.
