    I am loading .45 ACP for my Rock Island 1911 FS-Match. I am loading 200 grain semi-wad cutter lead. I am casting my own bullets with an RCBS 45-201-SWC ( http://www.midwayusa.com/viewProduct/?productNumber=187705 ) mold. I am using 5.0 grains of 231 and winchester primers. Brass is mixed. I am having a problem with the gun cycling. When I shoot it the gun lacks about a 1/4 inch of going into full lock up. I can push on the back of the slide and the round will chamber and fire. It does this atleast 3 times per 8 round clip. My OAL I am using is 1.235. I am leaving the shoulder of the bullet about 10 thousandths above the case.


    Any ideas of what it could be?

    Tighten your crimp a bit, should fix you right up.

    Good suggestion, would like to add, when a round hangs up, pull it back out of the chamber to see if your bullet has a mark on it, as though it is catching on the feed ramp. Also, are your rounds free of lube on the exterior? That can stop or slow down the slide enough to not chamber completely. Just a couple of things that came to mind.

    What are you using for a sizing die ? If it's not going in fully, the base might be just a tad out of spec.
    ALSO, you say the brass is mixed, is it the SAME headstamp screwing up ?
    Is it A-Merc brass by any chance ? THAT crap needs to be culled from your brass mix, as it is absolute GARBAGE.
    Some of the other stuff you might have a problem with is S&B, some lots load & function perfectly, others are not so good. I rather suspect their QC.

    Do your rounds fit freely in the chamber? Do you have a case gauge (you should)?

    Im not using a crimp. Should I bust out and buy the taper crimp die or factory crimp die? I'm not sure which one I need. Im not sure which head stamp is screwing up but I've just been shoving them in and shooting. If I do take it out put it back in the mag it doesnt jam on that one.

    I personally dont think its a gun thing but more the ammo.

    Also take the barrel out and the rounds fit flush with the top of the barrel.

    Jack, would chamfering the cases on the out side help me any? or you think it's the crimp?

    You just need a slight taper crimp to remove any bell from flaring the case.

    I don't use the lee FCD. Never had the need. What dies are you using? You most likely are crimping in the seating die, which will work fine if adjusted correctly. You'll have to wait on Jack for that I use a separate crimp die and it would be hard for me to explain the seating and crimping in one. I understand it, I have no problem with it, it is just not my thing.

    is it like seating a bullet and roll crimping in one die foir revolvers?

    I believe they're a lee set. I'm not really sure. If I'm not mistaken the seating die doesnt crimp is just makes the case straight again after belling. Right?

    If you're seating & crimping in one die, best to double check your die adjustment.
    I always run a VISABLE taper on my 45's.
    It's probably no more than .003"-.005" but it can be seen.

    most .45ACP die sets are taper crimp, except those that are 45 auto-rim specific (same die, needs different crimp)

    Hence the trouble you are having. ALWAYS CRIMP, ALWAYS. I am not sure what reloading "guru" started this ugly rumore about not needing to crimp, but on semiauto rounds, it is the only way to gain reliable feeding, especially when using lead bullets & belling the case mouth.

    To over simplify it, back out the seating stem and lower the body of the die an equal amount. The OAL will be the same but the crimp will be tighter. Yes you are removing the bell here, but VN350 said a little more then just flattened out.

    The lower the body of the die is in the tool head or press the more crimp you will have. You can have too much don't over do it.

    Like the others said, very light crimp. You can crimp in the seating die.

    I agree. I have a RIA 1911 and can't believe how nice it is and how good it shoots for the price.

    Quit being a wussie, crimp that thing like stomping on a June Bug with a pair of Doc Martins and go shoot. The worst that's going to happen is the extractor is going to hold headspace for the round.

    (How's that for sensitive loading advice... I should'a been a politician. :whistling:)
