    I am about to throw a fit!!! 🤬

    I have been reloading for 20+ years and have never had the issues I am having with figuring out 10mm. Ive made 30 dummy rounds so far and only one was correct.

    #1- Resize brass, fits perfectly in gauge (check)
    #2- Bell the case mouth (check)
    #3- Insert projectile and seat to 1.26" (check)
    #4- Taper crimp and poof....I am never able to get it to crimp in a manner that allows the round to fit into the guage more than 1/2 way.

    I followed the instructions for the taper crimp and even tried setting it by using a factory round. I dont know where the problem is and Im getting a little testy about it.

    Most of the time I find when I have a similar issue, it's that I flare too much, and the crimp can't get it all

    If you can find one (difficult right now) try a Lee carbide factory crimp die.

    How big are you sizing the boolits?
    What are you belling the case mouth with --Bell should barely allow the boolit to start

    1. Lee factory crimp die
    2. measure case length, esp if new Starline case
    3. gauges sometimes are useful, but mine normally sit in their blue box- the barrel is your best gauge

    Cut back on the amount of crimp pressure and give it another try. Sometimes the crimp will compress the case causing it to bulge in the middle.
    Sometimes it takes a second box of boolits to clear my head.

    +1 for the chamber fit .

    Will they fit in the chamber of your handgun? I've been loading successfully for 44 years and never owned a gauge.

    I suspect the crimp. Are you seating and crimping in one step? That can cause the problem in auto pistols. I usually seat then crimp either roll or taper in a separate step. Use the plunk test before crimping if it doesn't plunk then seat the bullet a little deeper until it drops into the chamber without an assist.

    Rotate the round 1/2 turn in the crimp die and crimp again. I've had several factory crimp dies act like that.

    Will it plunk? I've never bought a gauge for any of my ammo. I already have one.

    I seat then crimp separately.
    I've also had a Hornady taper crimp die for 9mm/.38/.357 cause a bulge in the middle of .38s if I got too 'aggressive' with it.
    Less flare, and less crimp fixed it for me.

    Ok so I did a "plunk test" into my Dan wesson 1911 barrel. The test rounds fit perfectly but still wont fit in the guage. The factory rounds fit the guage with no issues but both rounds appear to fit exactly the same in the barrel......(expletives).

    The chamber of your firearm should be the gauge, since that's where the ammunition you build will be fired. I've been reloading 10mm for years and years, and for multiple firearms (semi-auto handguns, a S&S 610 revolver and 10mm AR Carbine). I don't use a gauge, however I do use the firearms chambers.

    Hope this helps.

    Maybe throw the gauge away? Looks like your problem is solved. Good deal!

    Please provide a picture of your bullet and give the diameter. If the bullet has a shoulder as do swc bullets, then the shoulder may be hitting the ring that head spaces the case. If so seating it deeper will fix the problem. Too the gauge might not be in spec.

    These are fmj-fps. Im seating to 1.26" which is identical to the factory round I am duplicating.
