    That's good to hear. Now I won't keep anticipating a problem that won't likely appear. Thanks, guys.

    This thread started out discussing a real problem and its solution. It's worth keeping the solution in the back of your mind. Just in case...

    C4W,
    I went and readjusted the decapper/sizer die and sized 10 cases.
    I sized them all and measured them.

    4 were right at .424, SAMI max, at the base.
    6 were .421-.423 near the base.

    I flipped the 4 over and they were all Winchester brass.
    The other 6 were blazer, federal, and remington.

    I think I just found out why I am getting some cases a lil larger than all the others. They are either made that way at the factory, or they are weaker.

    That is still good news because they are all within SAAMI spec. The chamber is bigger then that spec. Even a tight KKM is bigger then that spec. They will work fine as long as the crimp is right and the bullet is seated straight.

    Out all of my reloads, the largest diameters is always at the base. I've never had the case come in larger around the bullet than at the base.

    You are saying yes & no. A case gage can NOT tell you if OAL is correct. They are mostly set for max SAAMI length, not helpful @ all. As you note, it has to fit your mag & bbl. OAL is ALWAYS gun & bullet specific, a gage is almost worthless for checking OAL.:dunno:

    In the reloading manuals, are the dimensions given on each calibers load data SAMI max?

    I have always thought of case gauges as diameter and headspace checks.

    OAL, have to use a bbl and or magazine.

  8. I load to 1.185 vs. SAMI spec of 1.135 for 40 S&W. I have been loading to 1.212.
    By shortening the round a little, I raised the pressure to tune my load without adding more powder. The gun still runs fine. Generally the magazine will be the limiting factor in OAL.
