Having trouble with proper feeding

    I'm shooting a Kahr CW9 the load data I have is for a 4' Barrel gun, mine is 3" how much should I modify my loads to ensure better cycling and rechambering?
    The current is:
    Powder: Winchester AutoComp
    Charge: 5.2 gr
    Bullet Type: Hornaday XTP
    Bullet Weight: 90gr
    COAL: 1.040

    They seem a little weak when I shoot them as far as recoil goes and I know the gun functions well with factory ammo. My concern is though that the MAX load is 5.1 in my book, I loaded most with 5.2 trying to compensate for the smaller bullet and shorter barrel.

    Are you crimping? I use a taper crimp on 9mm. My friend was having feeding issues and he wasn't crimping. I taper crimped some for him and it functioned good after that. Just a thought.

    Use a 115 or 124 grain bullet.

    A 90 grain in a subcompact may be difficult to get a proper recoil impulse to operate the slide at less then max load level.

    Your Kahr was designed around standard 9mm bullet weight, which is 115-124 grains.

    And your 5.2 gr Charge is well below the recommended Starting load with Autocomp powder according to Hodgdon data.

    The Starting load with a 90 XTP is 6.1 grains.
    MAX is 6.5.

    Why would you use less than Hodgdon's starting point?

    AutoComp's range is 6.1 - 6.5 for a 90 gr Speer Gold Dot.
    For an XTP, I'd start about the same, 6.1, & work up from there.

    Thank you

    Thanks for the input, I was going off the data printed in the book I have here at home. The data was for 100 gr bullets, I tried to slightly increase it based off that information.

    Most powder vendors have load data on their websites now. Very useful as a secondary source to augment book data.
