  5. While I don't shoot a lot of 223 I have yet to to trim any brass fired out of my AR. Some cases have been reloaded 4 or 5 times. They all chamber and go bang. So far it has been pretty cost effective I'd say.

    A Lee trimmer in a variable speed drill will work.

    You're taking a tremendous chance by not trimming your brass.

    Brass increases in length after each firing, especially after the first firing.

    When you chamber an over length case, the mouth of the case is jammed against
    the forward part of the chamber.

    This drastically raises chamber pressure to a dangerous level.

    Sooner or later you'll damage or even destroy your rifle, and may even
    injure yourself severely.

    :agree: I too would get the Possum Hollow Kwick with drill adapter. Works pretty well. Mount it on vice or press.

    This is my exact setup. Possum Hollow Kwick Trimmer and their drill adapter. BTW, the drill adapter also holds a Hornady deburrer/chamfering tool.

    It is a three batch operation - first everything gets trimmed with the KT, change over to the chamferer and reprocess everything, then the deburrer. Takes me appx. 2 hours, if I remember correctly, to trim, chamfer and deburr a little over 500 cases.

    The key is to have a good setup to eliminate as much hand/arm movement as possible. When deburring/chamfering, pick up two cases at a time and process both before tossing into the "finished" container.

    Just take the handle off the case trimmer and stick the shaft into a

    It definitely makes case trimming a whole lot easier.

    Another vote for Possom Hollow. I use a 223 and 308 trimmer chucked into my drill. Nice and quick.
  14. Those PH trimmers are hard to find. Looked at my regular supply houses and they are all on back order.

    I once went down to the farm with what I thought was a bag of sized and trimmed 308 to load for a belt fed 308 and once I got there I noticed it was only sized. With no trimmer I took a section of 1.5" barstock and drilled a hole through the size of the mouth and then drilled another almost all the way through the size of the base, so the part that needed to be trimmed off stuck out (I know I had a lathe but no trimmer). A light touch on the belt sander knocked off the excess and after 200 cases almost had the end of the barstock polished of machine marks. By far the most lowbuck way I have done it and 2nd in speed only to the dillon trimmer. Lee makes a "file" trim die that works the same way. When we switiched to shooting tannerite the ammo had no problem hitting the small containers <3" 100% at somewhere around 100 yds, I was impressed, using such crude methods.

    No photo but it is pretty much like a large diameter casegauge except that it only located the case by the mouth, base and shoulder.

    I use an old power window motor to run a 2nd hand forester that is more precise (it should be at least) but is slower and cost around $30 vs free.


    For speed the dillon on a 650 will size and trim 1800 an hour.

    Wear eye protection, trust me at the speed that drill is going (doesn't need to be that fast with the trimmer) your eyes are in line with impact.

    I know from experience.......
  18. That's what I use and it's hard to find a cheaper trimmer then the Lee's.
  19. i use a possum hollow trimmer. i honestly never tried to put the trimmer into my drill chuck but i do place case heads into my cordless drill and hold my PH trimmer in the other. Here is a video i shot for a buddy of me trimming a .308 case.

    for whatever reason, i get an error if i copy the imbed link from youtube here. the link above is active though.

    hands down the fastest is the dillon press mounted case trimmer. 1800 rounds an hour is not an exageration. it may not be the cheapest, but will be in the long run.
    do yourself a favor and spring for the dillon trimmer.
