    Default 300 blackout cutting jig **FAST**

    I have made a tool to aid those of us using a Harbor freight chop saw.

    This jig simply bolts in with the supplied bolts and greatly speeds and "standardizes" the rough cut off operation. Using this jig gives you a rough cut case a few thousands long with a nice even mouth. No more uneven mouths catching on the final trimmer!

    To use it;
    Just unscrew the thumb screw, catch the nut for reuse and set your clamp to the side.
    Bolt it in using your 3mm allen wrench and start cutting. My friends are cutting around 30 cases a minute fairly easily. Just slide the case in from the left, the case rim catches on a protrusion, chop it, push the next case in against the base of the just cut case.

    The just cut case gets ejected under spring power out the right side a couple inches and the next snaps in place!

    This means your right hand never has to leave the saw handle and your left hand is feeding the cases.

    Occasionally you will find a case hangs up. Almost always it is a damaged rim. I usually shoot a little shot of thin lubricant (Hornady one shot, silicone lube etc) into the jig before using if it has been sitting a few days and everything runs smoothly.

    Here's the saw it is designed for. (pretty cheap from Harbor Freight)








    Sorry for the short video, I am not smart phone upload savvy...
    Notice the ejection of the cut case, If you put this at the end of a bench with a bucket below it does a good job of catching them.






    These are $50 shipped. (fees included) If you use a USPS money order. PM me for address.


    These are well worth it. Check out all the feedback on 300blktalk.com
    Ppal to vonzep58(removethis)@yahoo.com do not assume ppal puts your address on the pmt info. sometimes it does not.

    Can that be made to trim them to 1" for making 7.62x25 from .223?

    not my video, a customers


    It should get them VERY close to 7.62x25 length but you will need to use a couple washers to catch the left side adjusting slot. if you want one made that will be designed to get there without washers and such let me know.

    I think you'd have a big market for the 223 to 762X25 tok conversions. I know I'd be interested. I started making them using a copper pipe cutter but it's a slow process...... B2B

    I am going to be in the shop for several days. Someone here or elsewhere asked me to look at this (was it you?) I was planning on making a few (5-10) to do that.

    That may have been me. Had a few rough days at work, had to stay late with broken airplanes, etc. I would like one purpose built for 7.62x25.
