    That needs to be re-done without the big mitts in the way ☺, or maybe the camera on the other side to better see what you are doing.

    I was thinking the same thing. Sounds interesting, id like to see the details. But its dark, bad camera angle and arms are in the way blocking most of the view. If you dont mind. Re do it with better light and closer, and not blocking the view. Thanks.

    The Harbor Freight saw has been great for trimming a lot of brass from cases that I am forming to other calibers. I love to use my 41 Swiss Vetterli for plinking/informal target practice...and that huge boolit makes a satisfying thwak when it hits the target. Fireforming 8MM Lebel brass to 41 Swiss requires serious case trimming and the Harbor Freight saw makes short work of this chore...same for making 300 Blackout from fireformed 223 cases and for many other cartridge case conversions.

    Back in the mid 70's when I was doing 357 Herrett all I had was a Lyman Universal Trimmer. With normal pressure it took a month of Sundays to cut them to length. I discovered if you really jammed the cutters in each tooth would cut a nice curl and it was surprisingly quick and easy. Now I use a HF chop saw.

    What's a good case trimmer / deburrer for 50 caliber? I'm having a hard time finding anything that goes up that big.
    I have the HF cutoff saw but need something for final trimming.

    I believe some make a bigger cutter and correct pilot for their trimmers but length may also become an issue.

    Since the loaded neck dia is around .525 A 9/16 end mill could have a pilot ground on it. then the shank ground to fit in a 1/2" chuck and used in a drill press. I believe lee makes a case holder for 50 bmg other wise one would need to be made. 9/16 is .5625 dia so you might want to go to 5/8 end mill. ANother option for a vuttrt would be a counter bore with interchangeable pilots. This would only require a pilot be turned up.

    Forster makes two trimmers. One under 50 cal, the other 50 and up. If length is a component with your case, than be sure to get the long base with your trimmer. They have a couple of different base lengths. I had same situation. 50 cal and long..

    I use a Lee case holder in a drill press, a block of hardwood and a hacksaw blade.
    I can cut 100 cases in about 45 minutes.
    Go now and pour yourself a hot one...

    Large brass deburring tool

    Copper tubing deburring tool deburrs 3/16” to about 1 ½”. 45-70 bullet in photo for reference size.
    This what I use when forming .577 Snider and Martini Henry cases. Works for deburring I.D. and O.D. , trimming is another matter.

    I use like others the HF chop saw. Be careful it is a Deadly saw if used improperly. The wood Jig in the above photo Is interesting. I found a company called "Demeters Workshop" that makes pre made jigs in various calibers. I purchased 2 and do work well. You can alter the Plastic and use them for Other calibers not Listed

    If available I've used a trimming die with a single station press setup away from my loading. Just use the press shell holder and case cutter on a drill. It's MUCH faster than the little case cutting hand crank tools.

    I made a short video showing the case fixture/mandrel I made for use with the HF mini chop saw. It really works well.

    I found the 3D printed Cutting Jigs, To be a Lot better and easier. Not that this item is not well thought out but, i am unable to make such an item to fit In the saw, and there case specific. Several people are making Them and sold on Ebay

    Might as well throw my 2 coppers in for the HF chop saw. For years I used a Dremel type tool with a cut off blade. It worked pretty good for a lot of years but the little chop saw is better.
