    I find nothing on barnes site for this bullet.
    It's 115 gr. 9mm, and measures .68, being a rather long bullet.

    They suggest in their sent info of a hodgdon longshot load of 4.7 to 5.2 or
    Ramshot 4.5 to 5.0.

    I own neither powder.
    My choices are Unique, 231, pistol power, or 700x.
    Any suggestions here?

    I suppose if all else fails, I could bug their tech support.

    Thanks.

    HP bullets may be long but use the barrel drop test to determine the Max OAL and function check by feeding the dummy round from the magazine to determine the working OAL.

    Once you have the working OAL, I would use the lower of available published start/max load data to conduct your powder work up.

    That would be the thing to do.

    Apparently slow powder is better.
    SO rule out W231 and 700X.

    I believe Unique or Power Pistol would be your best choices.
    But I have to idea where to start or stop.

    But with Longshot?
    The Barnes Max load is very nearly the Hodgdon Start load with a conventional 115 grain bullet.

    The Barnes 115 data for Longshot (4.7 - 5.2) looks closer to Hodgdons Longshot 130 grain Sierra FMJ data then anything else. (Start 4.5 - Max 5.5)

    Ok, so that's what I did.
    here's what they say:
    231, 2.9-3.4
    700x, 3.1-3.6
    Power pistol, 4.5-5.0

    Having not hit the bench yet, I'm guessing just about any powder is going to make for a really full case, possibly compressed.
    I've never loaded a compressed powder load, the guy says it's ok.

    Trusting your advice, what would you go with RC?
    I'm gonna guess PP?

    Same as I said in post #3.
    Slower powder.

    So, Power Pistol.

    BTW: It makes little sense to me they gave you higher charges with 700x then with W-231 either.
    That is contrary to any load data for anything where you can directly compare the two.

    700-X is faster then W-231, So it should take less of it, not more??

    rc provided good info - use slower than Unique burn rate powders for full-power loads.

    If the bullet is really long and you are concerned about compressing the powder charge (especially with bulky flake powders), subtract the bullet length from the OAL and see if bullet seat depth is deeper than powder fill in the case.

    Of most of the powders available on the shelf these days, Longshot is not in short supply. It is because that bullet has such a long olgive profile, that the load data varies so much from other 115 gr. jacketed data, and is so specific to the XPB. As stated, I would go with a slower burning powder, and Longshot should definitely fit the bill to a T. Although I've not yet tried the XPB, I have used Longshot about 80% of the time for my jacketed 9mm needs.
