     if I travel to a match or  have to get up at 4:XX AM to get to a distant match, I shoot worse than I shoot a local match.  

     

    An alternative :   Possible that distant matches (Level II) are more difficult than local matches,  and

              

                                  Possible that the competition is fiercer at the Level II matches than at home.

     

    So, we might be shooting just as well as at home, but facing more difficulties with the match design

    and competition.   

     

    Just a thought ...

     

    I've travelled to distant matches and do NOT experience the problem you mentioned.

     

    Even the one Nationals Match I attended a decade ago was some of my best shooting (only two

    mistakes in the entire match) but the competition was fierce ....     :) 

  2. I'm surprised you're getting PF176 with only 7.5 g WAC under a MG 124 JHP. 

     

    What is the OAL ?

     

    Can you explain a little more what the "some extraction problems" are ?  And, how frequently ?

    Were you using this same load before, and the problems just started ?   Or, is this a new load ?

     

    Have you recently changed anything about your gun ?  Grip, safety, magwell, etc etc ?

     

    WAC is a very common powder to use for 9mm Major and .38 Super Major - shouldn't be the

    problem.   And PF 176 isn't super high - little bit, but shouldn't cause an extraction problem.

     

    WAC's burn rate makes it an acceptable powder for .38 Super, but a slower powder would be

    better - but again, it shouldn't cause problems.

     

    Is the brass new or used ?

  3. Any additional info you could provide, like gun, powder, bullet, OAL, how much powder,

    what kind of primer ?

     

    I've never seen anything like that - don't know where to start.  More info might be helpful.

      147gr @ 985fps JHPs in my PCC.  One bullet got set back a little.  I shot it anyway and had complete case head separation. 

      Another round did not feed smoothly but did chamber.  The case wall blew out.   

     

    But, those were not 9mm Major loads - probably a pretty fast powder ?

     

    With a lot of air space in the case from a low dose of powder ?

    Do I need the EGW U die if I want to  prevent setback in 9mm major?

     

    It's kind of tough to setback a 9mm Major, since there is

    so much powder in the case.  

     

    You might set it back a little, but it's not dangerous.    :) 

  6. Well deserved break from all that practice at the range.

     

    I got really tired of going to the range 4-6 times/week.

     

    This is really a LOT more fun, watching Gov Cuomo tell

    us the actual facts about the Virus, doing crossword

    puzzles and napping all day.

     

    HINT:   for those with a tiny sense of humor - this is

                 biting sarcasm.     :)

    take out/clean the seating die and reset it.

     

    seating die will fill up with bullet lube and seat your bullet shorter than you set it   

  8. Speed vs. recoil.

     

    Bet it depends on how hard you grip the gun.

     

    A VERY hard grip would probably favor a lighter gun, and

    MY kind of grip favors heavy gun and heavy bullets.

     

    But, a local GM (super GM, actually) just stuck steel grips

    on his 2011 and LOVES them - and he's Very Fast.

     

    Just my opinion, BTW.
