    Hello all, I just loaded a few .45 ACP loads some older Speer 200 Gr. JHP, these are the round ball loads. I was testing with my Ruger PK 90 and just about ever round would jam. After returning home I tried them in my Glock Model 21 and it would function perfectly. the Ruger works well with all other loads. I re-tested the OAL of my reloads and they were within specs.Whats up with this ??

    first off maybe nothing,its not unusual for a semi auto to dislike one load or another.having said that you have not said how they were jaming,it could just as easily be the magazines.i might add for you to chk oal on ammo that works,and adjust to that. old semperfi

    What do you mean by this? OAL can be critical in an auto-loader, your Ruger has it's own set of specs as to what will work and what will not. What works in the Glock may or may not work n he Ruger.

    More details on your load please. OAL, Powder, Powder charge, Crimp etc.

    i'd suggest check your crimp. if you dont have enough crimp and the bullets are being set back during cycling it could cause weird things to happen, not counting the spike in pressure.

    if the jamming was failure to lock into battery i'd say you have too strong a crimp and have deformed the cartridge enough it wont fully chamber. the glock chamber might be just a tad bigger, enough to make a difference

    You dont say how it is jamming you dont specify how it is it not cycling the fired round out not going fully to battery not firing once its in battery what is it actualy doing?

    Ie do they rounds have a glock potbelly and not letting the gun go to battery etc etc.

    I had the same problem with a batch of 45 rounds made in some Eastern Europe country, I think Hungary. The handgun is a New Colt Gov. A slight crimp solved the problem.

    I am using 6.5gr of Unique powder and the oal is 1.200".The jam is occuring on the first round out of the mag. The slide doesn't completely close but can be pushed close, the round fires ok and ejectes. It's not a big problem since I only have 200 of these.

    Hakasaw-My Hodgdon Data book shows an OAL of just below
    1.16 on a speer 200 gr. JHP.Not saying that this small amount
    may be the problem,but it might be.At first I thought maybe
    it may be a low powder charge,but 6.5 gr. of Unique in my
    Lyman book is almost max.I reload .45 ACP and I use W/W
    primers.W/W primers are not magnum primers,but they are
    a bit stronger than standard.May be that also.I'm not savy
    enough to comment on crimping.I just know I do crimp,but
    I only load them for a revolver.bayhawk

    COAL is 1.275" MAX for the .45ACP, and the shortest I have seen is 1.190, the case is .888 at minimum .898 at MAX, so 1.16 - .888 = .272.... gotta be a typo, you must mean 1.26" because a loaded case with .272" of the bullet protruding makes for one wierd lookin round that you cant crimp because the bullet would be seated waaaay past the ogive, and case capacity would be reduced to nearly nothing and the base of the bullet would be jammed against the web of the case and there would likely be a terrible bulge and the round wouldnt chamber in ANY weapon...

    And just so you know, so anyone that loads .45ACP knows, A properly crimped (taper crimp) .45ACP round will measure .470" at the casemouth...
