    Have you ever gotten your mil surp bore truly clean?

    With a half dozen mil surps in the collection, and after a mountain of patches and untold number of passes with bore brushes, I now firmly believe the bores will never be "spotless". While the rifles shoot cast boolit loads great I have learned to live with the dark patches. Lifes too short to sweat the small things.

    It's very hard to get all the crud out of all the pits and worked in pores of the steel.
    I posted a few threads about cleaning up the bores. You need to get through all the layers of powder,jacket, cartridge , jacket material. The worst thing is when you do get them close to spotless you start to see your bores are generally not that great.
    I use stainless steel brushes. To avoid that false blue.

    Depending on the condition of the metal under the crud , yes .

    I started with a pair of Mosin's, 43, and 44, round recievers. Good rifling, but very very dark. Lots of fouling.

    So I would shoot 20-30 rounds, and clean. Leaded it up with too small bullets, not good enough lube, too hot loads. Tried again, Loaded, shot, cleaned.

    And then all of a sudden I looked down the bore. And I saw silver from end to end.
    Clean bright shiny, sharp lands and polished grooves.

    Pits will probably stay dark. I was lucky, there was a couple of good rifles under all the cosmolene and copper fouling.

    Start paper patching.

    Easy, but it takes time; get them pretty clean, then one wet patch (Hoppe's #9), per month. A year or three later, done - the patches come out /clean/. Needless to say, this works better in my collectible milsurps rather than my 'shooters'.

    Only one a K31. My Turk 38 will be a long time but is clean just dark in spots. Took a week on that one cleaning 2 times a day just to get all the crud out. Thought rifling was gone until fourth day.

    well when it comes to mausers and springfields perhaps there is a good reason aftermarket barrels are rather plentiful/

    Paper will take you down to bare metal, especially paper that has titanium dioxide and clay.
    usually around 20 rounds at full jacketed speeds will do the job.
    it's all an educated guess,,,, till the trigger is pulled.

    I use foaming bore cleaner with the muzzle down, let sit a while, run a couple of patches through, and repeat until blue/black sludge stops dripping out. Takes a bit of time, but very little effort.

    Except for Swedish Mausers and Swiss K31s- No. If they didn't shoot after an overnight soak with Hoppe's and scrubbing, they got rebarreled or sold if they were matching/unaltered.
    I don't like scrubbing barrels.
    Best, Thomas.

    The paper-patching truly does work. I had a filthy, pitted Mosin Nagant that I got tired of scrubbing on, and the paper patching cleaned it right up. I took it one step further by dabbing a little JB Bore on a few of the patches. Bright & shiny and smoothed it out some...but still pitted It shoots great with Hornady 312 150gr J-Bullets.

    I mop them with Sweet's 7.62 and that gets down to bare metal. The dark spots are from muriatic primers and doesn't come out...

    +10. If is fouling Sweets will get it ALL out. If it's rust, lapping is the only way.

    Milsurps with unpitted bores; yes.

    Pitted barrels which have been chemically cleaned to remove all prior metal fouling and corrosion, and then well cleaned with Kroil and JB, when necessary using a lead lap with AA Clover to remove tight spots, will shoot cast bullets just fine if the bullets FIT and are well lubricated.

    One of my best shooting cast bullet rifles is a Sako M28/30 Civil Guard's rifle dated 1932 which I got for free because it had a "dark but strong" bore and the fellow who paid $39.95 for it thought he got robbed.

    I cleaned it well, lapped it and a few weeks later proceeded to clean his clock in a CBA military cast bullet match with it. Richard Hoch told me years ago that "clean, pitted bores hold the lube better" and I thought he was smoking dope, until I tried it.

    I shoot NOE clone of #314299 cast of wheelweights, lubed with 50-50 Alox Beeswax and I conditioned the bore by firing mild loads with #314299 as-cast, unsized, wheelweights, Lee Liquid Alox, 6 grains of Bullseye, no gascheck. Wiped bore with wet patches with Kroil or Ed's Red every 5 shots, then one dry patch and dry the chamber, repeated for the first 100 shots.

    After that I wet patched and dry patched every ten shots for the next 100. A

    After that I went back to my usual load with #314299 sized .314", 50-50 Alox-Beeswax, Hornady GC and 16 grs. of #2400. NEVER brushed the barrel again in the last 20 years, but always clean with wet Ed's Red patch then dry patch and dry chamber before shooting. When done shooting leave barrel wet, then before shooting again wet-patch, dry-patch, dry chamber and shoot.

    You look at the bore now and it is shiny. The pits are filled with lead. The rifle NEVER sees a jacketed bullet or a "hot" load. I shoot 6 grains of Bullseye at 100 yards and 16 grains of #2400 at 200 yards. Rifle routinely shoots 4-5 inch TEN-SHOT groups at 200 yards. with iron sights. As well as my M39 with new barrel. Who'd a thunk it!

    I always enjoyed visiting with Richard Hoch at his shop in Montrose. Dave Farmer bought his business and is still making his design of top pour molds.

    OP75 actually read what I said. He is correct although I prefer a professional fire lapping kit to valve grinding compound.
