    anybody fire-lap their barrels??

    years ago when i was playing with heavy-barrels, my gunsmith was a gentleman named sealy masker, who ended up in the bench-rest hall of fame, suggested to me to get a neco fire-lap kit and try it on some rifles. i did, and boy,, will that slick a barel right up. it absolutely adds some accuracy , along with a cryo job, to your trusty old 30-06 deer rifle. i also firee-lapped my colt h-bar, and a bushmaster dcm service rifle. i realize that a m-4 is not a match rifle, but they won't foul near as bad, and the bore will clean up quicker and easier with a lapped barrel. the barrel on my cle varmit is a 22"krieger, which is hand-lapped, the service rifles are as smooth as it is,patch goes right through them. ust was wondering if anybody does this???comments,,please [ i tried moly -coated bullets for a while,, gave up on them]

    Tried both shooting the heck out of it and "breaking it in" with no appreciable diference. I trust Gale McMillan.

    Pass.

    what did gale mcmillan say?? david tubb thinks enough of fire-lapping to bring his own line of imbedded bullets to market. i certainly trust his judgement, pertaining to rifles. it did for a fact improve the accuracy on some of my heavy-barrels, definately fouls less. just what high-power shooters are looking for, 80 rounds per match, no cleaning. i brought this up here for the less fouling angle. [which is always a good thing]

    I believe it depends on the starting quality of the barrel. If you are alreday running Pac-Nor or Krieger, they've already been lapped. If running a bone stock Wilson, they haven't.

    Plenty of good smiths offer lapping as a service. It works. Fire lapping just allows someone to get teh same results.

    How much accuracy? Anybody do a before and after test? It seems to me that a regular deer rifle has so many other accuracy handicaps, such as relatively light barrel, crummy trigger, walnut stock without bedding, cheap scope with slightly wandering zero and iffy adjustments, etc., that fire-lapping wouldn't make a noticeable and consistent difference. But if fire-lapping doesn't cost much and has a placebo effect ("now my rifle is accurate so I must live up to it!"), then go for it.

    i also firee-lapped my colt h-bar, and a bushmaster dcm service rifle. i realize that a m-4 is not a match rifle, but they won't foul near as bad, and the bore will clean up quicker and easier with a lapped barrel. the barrel on my cle varmit is a 22"krieger, which is hand-lapped, the service rifles are as smooth as it is,patch goes right through them. ust was wondering if anybody does this???comments,,please
    Easier cleaning is always a plus, but again, how much accuracy difference does a before and after test show? My stainless DPMS highpower AR cleans up easily enough, and shoots at least expert up to 600 yards (I don't but the rifle does), without fire-lapping. But again, if it makes you think the rifle is more accurate and doesn't cost much, okeydoke.

    As far as fire-lapping chrome-lined service-grade M4 barrels, I don't see how that would make any difference, but I'll be glad to stand corrected if somebody can show otherwise.

    Lots of people have, but for others, it's still a mental support that gives them confidence in their rifle/ammo combination. Not that I'm the world's expert on match shooting, but probably we spend waaaaay too much time picking at teeny little equipment improvements instead of working on sight alignment, trigger control, and wind reading.
    When life gives you lemons, insert copper and zinc wires in them and repeatedly shock your tongue.

    i say to each their own, i've been doing what i do for too long now to change, [i hate change anyway, doesn't everyone]. frank white [compass lake] sends explicit instructions out with his krieger-barreled rifles, and it don't exactly match what krieger said on "long range inter.] i did agree completely with what someone said there about not mixing solvents [sweets followed by shooters choice] as i've seen first hand through a bore-scope what the inside of a barrel looks like[spider-web], especially stainless. i've been with the sinclair inter. crowd too long to jump ship now, due to some internet chatter. no one is gonna convince me that a fouled barrel will shot as well as a clean one, although there is some merit to the statemant "that some rough barrels will get smoothed over with copper, and shoot better." that was my initial point in starting this post, smooth them suckers out, they'll shoot better longer. krieger also cryo's and hand-laps their barrels before sending them out.
