CZ 75 tight chamber-OK?

gifbohane · Jan 13, 2020

Picture 2 is a chambered Remington factory round in my Stock CZ barrel. OAL is 1.080.

Picture 1 and 3 is a foto of my Blazer and Win reloads to 1.100.

All plonk to this same depth . It is considerable higher than my 9mm S & W barrel that seat flush to the top of the barrel. But I cannot believe that all three are seating too high. I was having some trouble with FTF on my stuff at 1.135. Here a painted dummy round twists (not easily) in the chamber but with some of the marker taken off just beyond the top of the case

Does this look right?

Have you checked that the "in battery" fit is correct?

Looks fine to me. The cartridge base is not supposed to sit flush with the nub - this is not a 1911 or Glock.

Where is the picture of the painted round?

The loaded round should rotate freely. If it rotated with resistance, and if paint is removed from the bullet, it means the bullet is touching the rifling and needs to be seated deeper.

Take one of your fired cases, size it, then drop it in the chamber. That will be your guide as to how far the case normally fits in the chamber.

Do a Beretta 92 next.

What fxvr said. Size a case. Drop it in. Loaded rounds should go in exactly as far.

I just went and pulled a -75B and SP-01 from the safe, pulled their barrels and dropped in rounds. They look exactly like yours do. You should be good

Roval & Click--Thank you for going out of your way to help me.

I just started reloading 9MM not to long ago and I had the same problem as you. I found some bullets made by SNS Castings that are 135 grain and has a different taper to allow longer O.A.L in a CZ barrel. I am going to try them soon. You might look into them also.
