    Well I'm not exactly sure but this question is asked often by new members beginning to roll their own. So I thought I'd share what the last reload looks like:

    Then again we do have some members that are experts with duct tape ;-)

    Not really. I usually spot any piece with a vertical split either by the distinctive "tinny" sound after tumbling or case gauge. Hand weighed AA9 with 13.8 gr & 180 gr XTP or FMJ (was shooting both). Fired out of a Coharie CA-89 (8.85" bbl).

    Cool looking gun! I know the commies in Kalifornia won't let me own one.

    Thx Steve. Sorry to hear how much control they have.

    If your primers are still tight and there is
    no cracks it is probably still good.


    I always measure the case head, rim and
    or extractor grove, if it does not grow and
    no cracks or splits, probably still good.

    Even Starline can produce a bad piece of brass now and then. It may be one in a thousand but it does happen. I have shot tons of their 10mm brass. I still have a few thousand new in my reloading room. I have had a couple that sp.it after one or two medium reloads.

    This case was not virgin & most likely had several loadings. It served me well.

    About 9 nine reloads when I kept track a while back. Some of my Starline has closer to 20 reloads.

    I'm looking at an Accurate Powders manual and for a 180 grain XTP their maximum is 13.5 grains (34,100 PSI).
    They go higher (14.5 grains) for a Speer JHP, but the pressure is lower (32,600).
    When the pressure gets kind of variable and unpredictable like that, it's time to get conservative on your loads. I can only guess why the XTP has higher pressure than the Speer JHP. They both have the same C.O.L., so I have to assume the XTP seats deeper than the Speer JHP.
    Do you recall if this was an XTP?
    Any thoughts on the length of the two bullets you were firing (seating depths, etc.)

    When I get new brass I usually
    load one piece fifteen times to see what happens,
    monitoring it every shot, with a max load.

    You don't know if you don't try.

    I loaded one 223 case seventy five times, still good,
    I ran out of bullets, one fed 30-06 case thirty five
    times, still good but had to trim it more than the
    223. Yes I was neck sizing them using a lee loader.

    The 06 load was with 125 grain bullets and the last
    five loads was all over 3350 fps, measured it every
    shot for head expansion, I think it only grew .0015''
    through the thirty five shots. That was around 20
    years ago.

    The XTp tends to have a longer bearing surface & shorter nose, so not only seats a bit deeper but more friction going down the bore.

    I would've thought max loads would shorten case life. I don't know of anyone that loads 9mm major in USPSA that keeps their brass. Most times, I'm trying to just get about 5 pts or so above power factor for whatever division I'm shooting. Even Limited 40 major, I'm just trying to get to 170-ish, so it doesn't really overstress the brass.

    MinervaDoe: not sure if XTP or FMJ
    COAL:
    XTP 1.251-1.255
    FMJ 1.253-1.257

    Also I think the Jacket is harder/thicker on the Hornady

    If your primers are still tight and there is
    no cracks it is probably still good.

    You need to measure your case head, web,
    extractor grove, rim, if they haven't grown
    any and your primers are still tight, your
    still good.

    Yep, loose primers, 100% sure sign your load in that case in that chamber is way too hot.

    Which is probably why 9 major guys don't pick up their brass... The ones I know are pushing a 124gr jhp at 1370fps to make 170PF. Heck, it's still bookin' at 1330fps to make 165.

    I think the 9mm major guys are nuts, but their asses. Anytime you are ruing a primer pocket on one reload, you are waaaay over pressure.
