    Cleaned the BREN 2 after about 500 rounds of cast boolits...powder coating is where it is at. The barrel looked great and cleaned up quick. Very minimal leading on the gas piston, came off in a jiffy. Gotta make more...

    762x39 My Report

    Started out with a Lee C312-155-2R in a 6cav mould. Couldn't get one nice looking boolit to drop but didn't matter.

    The material was range scrap. Air cooled, bulk shake and bake PC with a water drop after. Hornady gas checks after sized to 311. Weight was about 165 with a dress and shoes. After a week I tested for hardness and it's an 8.0. Yup, soft enough to deform the noses a little when seating. Not a problem in my 308 Win which I shoot a lot without PC at 1800fps with soft lube.

    Here they are.


    Test weapon was a Sig Sauer 556xi Russian with a 16" barrel topped with a 3x mini ACOG. Not the best for precision work. 30 rounds in total fired. Here's a look at the parts.






    Barrel looked fantastic. Lead on the piston and cylinder took only a few minutes to clean off with Chore Boy.

    My goal was to have a sustainable source of projectiles in case of a shortage or ban. I wanted fist size accuracy at 100 yards with the potential of some expansion. I've used this alloy to take deer in the past.

    Two powders used were 5744 and H4198. Here are the charges, velocities and 5 shot groups at 50 yards.

    5744 17.0gr 1615fps 3.0"
    5744 18.0gr 1623fps 0.9" WINNER!
    5744 19.0gr 1721fps 4.2"

    H4198 18.0gr 1549fps 4.4"
    H4198 19.0gr 1694fps 4.0"
    H4198 20.0gr 1722fps 5.1"



    As you can see there is one stand out winner here and it actually shoots better than my jacketed loads. I know a 5 shot group isn't the best data, but I was just trying to get a feel for what works. Now I'm going to load more and see if those groups hold up. I have no idea how magic works but it appears that charge has it. Go figure!

    That is very nice, well done!

    I got a dot on my BREN 2 the other day, green dot SIG MSR, a present, and the difference was noticeable. This is 8 out of 10 at 200 yards kneeling, braced. 129gr NOE powder coated.

    How fast are you pushing your boolits? What's the clean up like on the rifle? I never could get good accuracy with cast beyond 1800fps so I opted for a heavier boolit to keep my energy up.

    They are actually stepping out about 1750FPS. Nice noticeable interval between BANG and CLANG. Clean up is easy - the gas piston drops very easily once you know the trick on the thing. Disassembly is relatively quick, too, not as fast as the Scorpion, but quick enough for me.

    Now the next question - I found some CFE BLK locally. Apparently nobody around here uses it, because the bottles were quite dusty...anyone used this with cast loads?

    I was wondering this as well
    Failure is not an Option

    Steve, the surface imperfections on your boolits tell me that your mold is too cold. Try heating on a hotplate for a bit.
