    David tubbs fire lapping kit

    Have a rifle thatís Virtually brand new 161 rounds so far its copper Fouelung really bad
    Which you expect while the rifle breaks in but I would of thought it would of calmed down by now
    Plus the Velocityís are very slow like really slow

    Has anyone tried fire lapping a barrel?

    I could get it hand laped but I think it could be costly due to the Process being time consuming

    Heres a video of a guy doing his 300wm with borescope footage
    After each stage of the process

    Suggestions
    Comments???

    Cheers

    Hand lapping is not a major, done it for a couple of barrels and settled them down nicely. Give me a shout if you want a hand, you’re only round the corner

    Used the Wheeler kit on a few barrels. Worked very nicely with good results.

    I fire lapped an old 303 that looked buggered but was so black i coudnt tell. Used a slug of silica flour loaded in a 303 case with some shotgun powder to get it going. After two shots it was shiny bright and yep it was buggered but at least i couls see how badly.
    Firing a charge of valve grinding compound down the bore is something you would not want to do too often.

    I went over to @chainsaw ‘s today and he polished the bore up abit for me
    I just put a oil patch through before putting away man what a Difference before the rod would jam and jurk its way down the bore and the handle wouldn’t even rotate with the rifleing
    Now smooth as silk and rotates its way all the way down
    And the slightly tight spot near the muzzle is gone
    Thanks heaps pete

    Shooting it tomorrow so proof will be in the pudding
    chainsaw and viper like this.

    It’s not something you’d do on a newish rifle. There’s plenty of copper specific solutions that I’d use first. Possibly also try a different projectile, some foul worse than others.
    More meplat, more better.

    Yeah I was told it was pretty hash so was pretty keen to avoid it. seemed to have at least improved it with just a light polish thanks to pete

    Hopefully the lap and polish will settle the barrel down, keep me posted how you get on.

    @chainsaw range report so i fired 43 rounds total
    Gained 40fps on the average Velocity and groups with the 140s tightened slightly from 0.8 to 0.7
    Copper fouling is still bad but has improved alot

    Could do with a little more?? What do you think

    the improvements suggest we are on the right path - good to see accuracy retained or slightly improved.
    Was the Cu fouling evident after just a few rounds or only after the 40 or so ?
    Another lap and polish should help further.

    @chainsaw just shot to be honest
    Didn’t clean at all probably should of to find out
    It was easier to clean than last time I went to the range and last time i only fired 25

    So its on the right track
