    Just got my M9. Tried out an old favorite for my CZ, 147gr, 3.3gr Titegroup. Lots of FTE's. The M9 is new so maybe it needs breaking in. Next I used 125gr. Zero JHP with 4.2gr. Titegroup at 1.13 O.A.L. These would not chamber. Just loaded some of the 125's at 1.115 O.A.L. Going to try these tomorrow. It seems the M9 does not like wimp loads or certain bullet shapes [like the Zero 125's]. No problems with the WW white box.

    I use the Montana Gold 147 and the MG 115 fmj. I have no problems if I load them to 125,000 power factor. Make sure you crimp them very well and use a Lee OEM crimping die.

    My tightest chambered (and throated) 9x19 is my CZ85; or I should say it was, until my M9. The throat in the Steyr is shallower and it caused some problems with some of my reloads. Usually it takes a only very small change in the seating depth to remedy the problem.

    I, too, had problems with Titegroup in the Steyr. Being a fast burner, Titegroup charge weights end up on the low side (even with max loads), apparently low enough to drop the recoil energy below the threshold needed for reliable function. Try switching to a slower burner, like something in the vicinity of AA#5 or AA#7, and stick with full power loads.

    Thanks guys. I am going to try only full power loads and move to VV N340 for a little slower powder.

    That could well be true; I don't have a CZ75 to compare the 85 to and I don't have any other experience that would run counter to it.

    I've got four 9x19's, and I'd rank them as follows (loosest to tightest chamber): Tanfoglio Witness, FEG Hi-Power Clone, CZ85 Combat, Steyr M9. Of course, all guns are individuals to a certain degree so I'd hate to cut these rankings into stone without a larger sample.

    I had problems with berry 124 hp in my s9 at 1.110. Copy of my previous post.


    All
    I recently loaded 124g Berry HP 9MM bullets on mixed brass with aa#7. I used a cartridge gauge to check dimensions and I actually shot at least 50 rounds thru several Glocks (g34,g19,g26) with no problems. The oal was 1.110 which is well with oal limit of 1.169. In the s9 barrel the round would not chamber.
    Does anyone have any idea what the chamber cut of the s9 is like?

    It almost seems like my chamber is under cut or short in the length. The berry bullet taper might be part of the problem but I suspect the S9 since the rounds work in my Glocks.

    Anyone with a similar experience?

    Other HP bullet that FTF?

    Thanks
    Jeff
