  1. I have a fix for you, louu.  Make up six moonclips or speedloaders with dummy rounds.  Put on all your shooting gear and head to your dry firing area.  Draw and shoot as fast as you can, but only accept "A" hits.  You are an A class shooter, so you know how to call your shots.  Go through all six moonclips reloading at speed.  However, if you shoot a shot that is NOT an alpha stop.  Holster, put your dummy rounds back on your belt.  Now draw, transfer to your weak hand, shoot, reload using your other hand and stop when you call a bad shot.  If you make it through all 36 or 48 trigger pulls with good alpha hits switch hands and repeat as desired.

    Have you taken actual measurements so you can know the range which you will need to fit?

     

    Then try contacting Dave Hearth, on this site as Hearthco.  PM him and see if he can make you some that will work.

    Yes sir I have.  Any of brass with an extractor groove diameter equal to or less than 0.333" would not stay in the moonclip.  The challenge is that 76/200 are too small, but the remaining 134 fit great with my moonclips.  

    I remember the days when I shot my 625 with Ranch Products clips and range pick up brass and never gave this stuff a second thought.  Ignorance was kind of nice.

  3. I forgot that I have some TK clips that are 0.050" thick.  They hold the offending brass.  Some of it fits tighter that others, but loaded rounds stay in the clip after a gentle shake.  Unfortunately, the way my cylinder is cut I cannot close the cylinder with the thick moonclips.

    See if you can find some moon clips that have slits between the rounds. Those should be more springy and hold variable sizes better (theoretically). If I were making moon clips, that's what I'd do. Then one clip would fit all the different brands of brass for that caliber. The clip would fit the smallest size, but be able to spring open enough for the largest, or any in between. You might check out RIMZ polymer moonclips. I don't know if they are suitable for competition.

    I wonder if its time for one of those 3D printers.  Have you tried one yet for stuff like this?

    SAAMI spec on the extractor groove diameter is 0.347   +0.00  / - 0.020

    And that is too much for a regular old moon clip to work with 0.347 grooves and 0.327 grooves.

    Starline says their smallest is 0.333, so their standards are a little tighter.  Unfortunately, that is a little too small.

  6. Let me start by saying that I think highly of Starline products.  I use them in 38 special.  I am finally getting around to finishing my setup for a GP-100 that I had rebored to 40S&W.  Harold Nicholson did a great job on that gun.  The balance is great and it reloads like my old 625.  The problem that I have is that the extractor groove dimension on my Starline brass is not consistent.  I set my calipers to 0.333" and anything that fits does not clip in my TK moon clips.  The moon clips are spot on.  Out of 200 rounds of Starline 40 S&W brass I had 76 that were too loose for my moon clips.  I understand SAAMI specs and manufacturing tolerances allow the differences.  It just doesn't help with my moon clips.

    Have any of you fine folks worked with a brass manufacturer to order brass with a specific extractor groove dimension?

    Thanks,

    Javier

    Being a lefty, I've been looking for an extended release for GP100 for a while.  Thought I had a line on a gunsmith who made them but it didn't pan out.  Made a couple of my own mock-ups. The first one used a modified factory smith release (talk about irony) and the second one used a piece of flat stock I had installed on a Blackhawk hammer to lower it before you could get the Super BH hammers and install them.  I used liquid weld to put them on.  As is, not really meant to shoot a match just to function test.  The function test real well and make my reloads a lot quicker.

     

    Will be glad to see Hogue come out with some.

    Another lefty here.  Talk to Harold Nicholson about the release that he made for me.  I just have to sweep my finger across the release.  It is a work of art.

    Yes. GP-100 grips fit, I have tested. So do the spring kits for the GP-100 that will reduce the DA trigger pull.

    Excellent news.  I'm a fan of the old cocobolo wood insert grips. thanks
