45 acp

hey guys I have a problem with my 45 ACP loads, they fit in the gage drop right in fall right out on their own, I can load a magazine and run them through the pistol by hand no problems but take the same 12 bullets load them up and try to shoot them and almot all will keep the slide from going back to battery I get about 3/16 of an inch sticking out of the chamber, I measured a new round and the reloads I get about .002 - .005 difference but its about the same on my 40 S&W and that works fine. any thoughts, oh the 45 and the 40 are H&K USP's thanks

The variation in OAL you are getting is actually very good. I suspect the cause is either lack of power in the load or bullet profile is causing the problem. What powder and charge, what bullet weight/shape and OAL?

I am loading 6.5 of IMR 800X with a percision bullets 230gr round nose OLA I shoot for is 1.200 it's well within the case gage and the rounds are not even snug in the gage diameter wise.

I believe your overall cartridge length is too short to feed. Try lengthening to 1.260-1.265". This is better for a 230 grain RN

OK I'll give that a shot and let you know what happens, Thanks

 

 

Well it took a while but I got out to the range with some loaded to 1.260 and the second round would not feed all the way in to the chamber, I would say its the brass but it all clears the gage with ease or is that not fool proof? I mean if it had a bulge from a glock or something it would hang up in the case gage right?

The gage is cut to minimum chamber dimensions. Pull the barrel out of the handgun, and drop several rounds into the chamber. See if they fully enter, and freely fall out. If they don't, then size 10-15 pieces of brass and perform the same function with the sized empty cases. Please let me know what you find.

I tryed some loaded rounds 4 ouy of 5 would not seat all the way, then I sized up 15 brass that all seated, soooooo I must have something out of wack I guess I thought I set up by the book but I guess not, where would you start, seat or crimp die?

     Thanks
