    Okay, gave it a try several times since my last post. Reformed some old Imperial 30-06 brass in one of my 9.3X62s, and did the first shooting while fireforming the brass. The bore was lead free after five rounds.



    Here's the result of the last trip to the range. How's this for a hunting load at a 2236 fps? Northman 285 gr plain base, with a half inch square of old cotton towel wad, tamped down over powder, and slightly compressed COW filler to base of bullet. Group is 2.1 inches at 100 yards.



    Shot and chronographed three, three-shot groups, this was not the best one.


    This bullet penetrated six four-litre jugs of water, and was caught in the seventh. That's over 36" of water and about 1/8 inch of plastic!



    You can see how cleanly the bullet is engraved by the rifling. Note, as well, how near perfect the base of the bullet is. No fusion has taken place at all.



    Care to guess the recovered weight?

    There was no unburned powder in bore or on the snow, and best of all, no leading! One patch of bore solvent, and one of KROIL, and it is ready to go again!

    When I was shooting a lot of .38 Special lead bullets through my Ruger GP100, it would lead up terribley. This was around 1990 and Outers sold a reverse electroplaiting kit that would remove lead or copper. The first time I used it I was AMAZED how much lead it removed from the cylinder bores and the barrel AND it didn't harm the finish on them.

    Over the years, I've used it on any firearm that leaded up.

    BUT last year I used almost all of the leadout and tried to buy some only to find out that Outers no longer manufactures it! So I did a search on the internet, found a website that gave the chemicals for the solution, then bought them from an online place in PA called Post Apple Scientific, Inc. 8893 Gulf Road, North East, PA 16428Phone: 814-725-3330 ( http://www.postapplescientific.com/ ). The water is distilled water (I found it at the loacl gorcery store!). The chemicals are lead acetate ACS crystals 100 G bottle and liquid amonia acetate .010% solution in a 500 ml bottle.

    I can't find the website right now but it was pretty straight forward as to the mixture of water to crystals to liquid chemical.

    I haven't as yet mixed the chemicals together though but from people who mixed their own said it worked exactly like Outers Leadout.

    PS: I just did a search and wouldn't you know it, there is a post telling how much to mix each cemical!

    I simply apply some kroil, chase it with a cleaning rod with a patch covered by a square cut from a copper scrub. I follow that with a tight Hoppe dampened patch. That usually gets it all. If necessary, rinse and repeat!

    Here are the latest 100 meter groups shot with the 285 gr Northman. Loaded one grain more CF8506, a half-inch square cotton towel wad, and COW to halfway up the neck.



    Removed the Leupold 4X heavy duplex,and replaced with a 6X for today's shoot. The left target is the first one, and first shot was near bottom of the paper. Right target is second three-shot group. The hole to right in that target is from a 270. With the two targets superimposed one over the other, those five shots after scope adjustment are in a tad over 1 1/4 inch.

    One of our range officers was there today, and checked the groups through a spotting scope while I was shooting. He was quite impressed that a plain base bullet could shoot that well at over 2200 fps. He was especially impressed after looking at the bore and saw this was all without leading. Continue to shoot this rifle with no leading at all. Just one pass with KROIL now, no solvent at all, between range sessions. The cotton wad/COW combo really works!

    This Husqvarna 9.3X62 Model 46 has a 24" barrel, and was supposed to become my dedicated skidoo rifle. Was planning to cut and crown the barrel at 20", but my friend won't let me do it.

    I have some rough spots in the bore of a old 38-55. Reading here about the COW method of removing leading and thought I'd give it a try on this old bore. Rough spots are about midway down a 20" barrel. Loaded up 5 rounds with 22gr. of 3031 with a cut down BP pistol wad on top of the powder charge. Weighed out 12gr. of COW and seated a normal 265 gr. GC boolit on top. Fired them and looked again at the rough spot. Rough spot turned out to be old leading and I'd reduced it to half of what it was in 5 rounds with the COW loads. Thinking I'm going to load up 20 more that way and fire, see what it looks like. Might end up with a good bore in this thing after all. Regardless of the results, the COW sure cleans up the bore on this old dog. I'd loaded with COW before for fire forming brass and it worked fine, never for the sole purpose of cleaning a bore.

    The 20 more loads of COW were made and fired, mixed results. Took more of the leading out, might still have about half of it left. Going to get a chore-boy pad and start in on it. Might get a can of PB blaster to go with it as well. This leading is old, could be more than 50 years in there. First 5 COW loads exposed just how much was there and removed some of it. Bore looked bad when I got this, might end up being much better than I thought after all of the lead is out.

    For pistol leading I use a dry patch on a brass jag (Midway) with a piece of Chore Girl (copper) snug fit.....dry. No solvents at this stage. Move copper around on jag to expose a rough surface to scrub bore . Try again. Dry patch next and verify progress.If fouling still is evident soak with your favorite solvent following instructions so as not to harm bore. Repeat as necessary. afish4570

    I recieved a call from Ted friday night and in the course of the conversation he related to me the advise on this thread and the results he had experienced with the C.O.W. loads. Having shot thousands of cast bullets in the past I had to get out and try it for myself as like many others I have suffered from leaded bores and poor accuracy because of it.
    Two words
    It works!!!
    I had a great range session today with my 30-06 and 165 grain beveled FB's and 169 gr CGC's . Each round consisted of 34 grains of IMR 4198 a half inch square piece of the wife's old dish towel tamped down onto the powder with a punch , cream of wheat to the top of the case. Compressed the load with the bullet and finished with a sturdy crimp.
    Velocity was 2320 fps averaged , the flat base accuracy was nothing to write home about but the gas checks were running 1.5- 3" groups @ 100 yds and the best part was that after almost 60 rounds down range No Leading!

    Another non-leaded barrel!

    Headed up to the range today to make a believer out of a new guy using cast bullets. Same 285 gr Northman plain base, cotton patch, and COW filler load as posted before, but shot in a different Husqvarna rifle, an FN98 with 24" barrel.


    Fireforming 30-06 brass to 9.3X62, we took three shots at 25, then here are the next six shots at 100 yd. Not too bad for a straight 2 1/2 power scope.





    Adjusted scope down to hit three inches high, and the rest were fired at silhouettes out to 300 meters. Average velocity was 2174 fps (about 100 fps less than in the other rifle).

    Ladies and Gentlemen, we have a new cast bullet shooter on board!
    Ted

    PS: Fifteen rounds fired and no leading at all. This is the second rifle with the same non-leading results.

    i use a short hardwood dowel and pound a very tight fitting pinch of choreboy down the barrel.
    one pass is all it takes
    when i have a ring in the cylinder from shooting 38s in a 357 i wrap the choreboy around and old brush and chuck it in my drill
    that removes it all in seconds.

    Put a cork in it, the muzzle that is, and mix 50/50 white vinegar (5% acidity) and hydrogen peroxide (3%). Pour it down the barrel. Lean the barrel in a corner inside a coffee can. Wait 15-20 minutes. Run rod down to pop out cork. Followed by a couple patches wet in 50/50 mix, then a couple dry patches. If needed, use a few strands of unraveled Chore Boy copper pot scrubber pads on a barrel brush. Repeat if heavily leaded. Finish with some Hoppes and oil if you want. So easy and inexpensive ($6 for a gallon of vinegar, hydrogen peroxide and Chore Boys). Took lead out of my barrel that Butch's Bore Shine didn't.

    Accidentally shot some undersized bullets through my .45-70 two weeks ago and ran out of my duplex 'cleaning' loads. I tried the chore boy method and it was scary how much lead was pushed out of the barrel. I just need to run a set of cleaner rounds and it should be lead free. It seems like the duration of heat and pressure from slower burning powder is remelting the lead in the bore and pushing it out, OR the bullet is bumped enough to scrape the lead out.
