    Loaded dummy rounds with 165 gr X-treme RN.  COL 1.150". Plunk tested no issue in my 75 SP01s.  Curious as to COL and bullet style, manufacturer, and jacketed/plated/lead/coated (i.e., Blue Bullets, et al) for the 147s that won't chamber in an S2.

    The following factory ammo did not pass the plunk test in my Accushadow 2:

     

    Eley Minor 9 124 grain

    Federal Syntech PCC 130 grain 

    Precision One 135 grain competition

    Federal American Eagle 147 grain

     

    The following factory ammo did pass the plunk test in my Accushadow 2:

     

    Blazer Brass 124 grain

    Freedom Munitions 124 grain RN

    Precision One 124 grain competition

     

    I'm currently using the Precision One 124 grain competition ammo for USPSA matches and haven't tested any additional factory ammo.

    Never reamed any of the barrels in my CZs and never any issues re feeding or chambering using bullets from 95 hrs to 147 so far -- Jacketed, plated, and coated and never straight lead.  In the near future will experiment with >147.  Curious to see what happens there.  Just sayin' and know Everyone's MMV.

     

    {Edit: Added comment on jacketed....}

    Have you plunked the ammo you're using?  My Accushadow 2 will not properly chamber 147 grain.  The bullet is hitting the rifling.  Even some 124 grain (like the Eley 124 grain competition) has the bullet hitting the rifling.  Check out the following to better understand the importance of using the correct ammo in a CZ ( Understanding Ammunition Shape and Dimension Issues (czfirearms.us) ).

  3. I have a CZC 13 lb. hammer spring with a stock firing pin and reduced power firing pin spring.  The trigger pulls are 7.5 lbs. DA and 3.25 lbs. SA.  I had 100% ignition with multiple makes of primer.  All of the primers were domestic (CCI, Winchester, etc.)

  4. Using my Accushadow 2 with 13 pound hammer spring, stock firing pin, and Rami firing pin spring I shot 100 rounds using Winchester primers and 100 rounds using CCI primers.  There were no failures or malfunctions of any kind.  The indentation in the primers was not as deep as when I used the extended firing pin, but still pretty deep.  Attached is a picture with the Winchester primer on the left and the CCI primer on the right.  I did not notice any significant difference between the two.PrimerIndentation.JPG.ca86830cd5acc57acbc71a5e270541a0.JPG

  5. I tried the Eley Minor 9mm 124 grain competition ammo in my Accushadow 2 but it didn't pass the plunk test (barely).  It would make the plunk sound when I dropped it into the chamber but would not fall freely when I inverted the barrel.  The bullet was just barely touching the rifling.  I shot the 100 rounds I purchased with no issues but didn't buy anymore.  I'm now using Precision One 9mm 124 grain competition ammo ( 9mm 124gr FMJ (REMANUFACTURED) COMPETITION - Precision ONe Ammunition ).  It plunks and freely falls when the barrel is inverted.

  6. Just received the stock firing pin from CZ Custom and installed it in my Accushadow 2.  Doing the pencil test I can hit an 8 foot high ceiling with the pistol at waist height.  I'll be going to the range this Saturday to test out my gun (13# hammer spring, stock firing pin, and Rami firing pin spring) with Winchester and CCI primers.  I'll report back my results.

  7. I make an L with my weak hand with the four fingers touching each other and the thumb out at 90 degrees to the fingers.  Place your weak hand thumb between the hammer and the gun and slowly rotate your fingers forward while pressing the trigger with your strong hand.  This will slowly roll your weak hand thumb out of the way of the hammer and gently lower it to the firing pin.  Practice this many times in dry fire until you are comfortable with it.  Then try it with live fire.

    And for those pick up their ammo from the ground after unloading, and lets say the range floor is earth, sand or gravel, I assume you are going to use the round you picked up again as long as it is not visibly damaged?

     

    I was thinking of wiping off the round with a rag just to make sure I don't get the gun/chamber dirtier than is necessary since I would like to use the same round, if possible, in the next stage. As for getting my ammo mixed up with others, someone told me to mark the rear of my rounds with a water-based permanent marker so I can easily identify my ammo if I had to pick them up. I just noticed though that I get marker ink all over the breechface after doing this. I hope this does not mess up my firing pin or the firing pin channel.

    I watched a match here and saw some guys wipe down their mags with a  rag after it gets dropped on the ground. I assume they use those same mags on the next stages. Was thinking of doing the same for rounds that fall after clearing the gun.

     

    I let my ejected round fall to the ground.  If I can spot it quickly I will pick it up.  If not I just ignore it and move on to the scoring.  Since I'm currently using remanufactured ammunition with mixed brass, I put a black dot on each primer to let me know the ammunition I picked up was mine.  The last thing I want to do is accidently pick up a 9mm major round and try to shoot it through my gun.

  9. USPSA classifier 13-05 states "perform a mandatory reload using the magazines/ammo on the table" and USPSA classifier 99-21 states "make a mandatory reload with a magazine taken from the shelf".  Is it within the rules to pickup the reload magazine when the gun is first picked up, put the magazine on a magnet, and then take the magazine off the magnet to reload?  I would think it would be, but I want to make sure.

  10. I'm using the DAA Max holster for my Accushadow 2.  Other than the handle of the gun sitting a little higher than I would like, it works well.

  11. I shoot USPSA 2/3 size targets ( https://www.amazon.com/Birchwood-Eze-Scorer-Practice-Target-18-Inch/dp/B00HQQSASU/ref=sr_1_3?crid=2226DADD3UZMF&keywords=birchwood+casey+eze-scorer+ipsc+practice+target&qid=1678658854&sprefix=birchwood+casey+ipsc%2Caps%2C642&sr=8-3 ) and 8 inch round targets ( https://www.amazon.com/Casey-Dirty-Bird-Target-inch/dp/B000STNWB2/ref=sr_1_2?crid=QQ5EHI0BVC2C&keywords=dirty%2Bbird%2Btargets&qid=1678658948&sprefix=dirty%2Bbird%2Btar%2Caps%2C138&sr=8-2&th=1 ) when I practice.  The 8 inch round targets are equal to a mini popper or 2/3 full size popper.  For the 2/3 size targets and poppers, 5 yards is equal to 7 1/2 yards, 7 yards is equal to 10 1/2 yards, and 10 yards is equal to 15 yards.  It really helps me practice where to aim on the target while I'm shooting.  It also allows me to simulate various classifiers by using a black sharpie and drawing lines on the target to represent hard cover/no shoots.  It's not exactly the same as the classifier, but allows me to get valuable practice time during my training at an indoor range.
