Re: Lapping a Barrel?

Are the bullets going thru the target canted or sideways?

I suspect that barrel is to far gone to be any good, and scrubbing the hell out of it with abrasive isn't going to help matters any.

If the barrel was rusted and pitted and you scrub with a bronze brush and oil thats fine, you are removing the bad stuff, rust ect.

But using a metric ton of abrasive is going to remove the good steel that remains, and by the sounds of it you have very little to spare.

    Take it to someone that has a bore scope and knows how to use it.

    Re: Lapping a Barrel?

    Lapping a barrel correctly is almost a art form because there are so many ways to screw one
    up that it is not recommended unless you realy know what you are doing.

    In your case you are trying to save a barrel that was fed a steady diet of corrosive ammo.(Ammo
    was corrosive until 1953 to 1955) so it is probably pitted as the others have said.

    There are many reasons that the rifle may not shoot and the barrel could be one of them
    but stock to action/barrel fit may be another.

    The bore scope is almost a must in these situations because looking down a barrel with a bore
    light normally only tels you that it is clean or dirty, The bore scope looks at the bore 90o to
    the rifling and will give a much better view of the condition of the barrel.

    There is another way to bring an old barrel around and that's with a bullet swage that can
    make over sized bullets. (.308 to .309) I have seen some match rifles that had been shot
    thousands of times come alive when fed over size bullets.

    Also with very little rifling left in a barrel sometimes the lighter bullets work better, so try
    a much lighter bullet.

    I would not clean the barrel any more if it is pitted and let the copper fill in some of the pitting
    and if there is enough rifling left it may do better.

    Just some things to try.

    That's an excellent question. My wife's sporterized '03, which was ruined by corrosive primers sometime before we were married, put bullets sideways through the target at 50 yards (the farthest away we could even hit paper with it).

    Barrels that have been ruined by corrosive primers are not salvagable in any practical sense.

    I rebarreled my wife's rifle.

    Re: Lapping a Barrel?

    I got it cleaned today I worked another two hrs, I put the Barreled Action in the rince tubs and used the bore brush and used some dry cleanser and not I have no blue patches just a real clean barrel. I did noticed when I went half way, I found an area that is real easy to push the patch..I think its bulge in the center of the barrel.


    Thanks for all your input.

    You might consider slugging it if you can't find a borescope someplace.

    Re: Lapping a Barrel?

    I have accsess to a Borescope, my friends have have two, both are gunsmiths, its a good idea and I will check it out..I need to finish this rifle its worth a few bucks I can turn a proffit but I just cant see myself selling it. Douglas has a barrel both in stainless and regular steal both and are air gage chamberings cut (matched) for the Springfield Rifles $310.00 and they are high quality.
