  1. I don't know all the details of the ammunition you are using, but with a 115gr FMJ with a BC of 0.140 and velocity of 1135, the numbers for 50 yards look to be.

    Trajectory

    Zero        40         50

    Yards     PoI         PoI

    0            -0.5       -0.5

    10          0.1          0.2

    20         0.3         0.6

    25         0.4         0.7

    30         0.3         0.7

    40         0.0         0.5

    50         -0.6        0.0

     

    So take your pick.  Both should allow essentially holding center at each range.

  2. I'm not certain ANY brass was designed to be reloaded.  Even when sold as cases you could argue that you load them as reloading is only after they have been fired.

     

    A commercial brass processor should cull any unusable cases - those with tears, cracks, mangled.

     

    Bottle-neck cases have some additional considerations than straight wall cases, but pose no special problems regarding using them for reloading.  They will need trimming periodically and you need to be certain to set the shoulder back a bit to facilitate chambering.  Semi-auto guns may require different sizing than bolt guns.

     

    Get some of the cases.  If you have questions, check with experienced reloaders in your group or ask questions here.

     

    Read the rifle reloading section of your manual(s).

     

     

  3. Many Open division shooters load the 9mm Luger to meet Major power factor.  They are over normal 9mm Luger specifications and should not be used in other guns not set up for the higher pressure.  Plus, I believe Open is the only division they would be scored as Major, so no other division has need of them.

     

    I have not looked at +P or +P+ specs of late, but I do not think they will meet Major requirements.

     

    You may want to expand your question to give more details of what you are looking for.
