So after loading up 100 rounds of .45ACP with 200grn lead semi-wadcuttter bullets, and testing them beforehand by dropping them in my barrel (they fell out just like my factory fmj rounds), it turns out that they will not chamber. They slide will just not go into battery. In fact, I had to put a screwdriver up the barrel and smack it to get one round (complete, not a squib) out of the chamber.

I am attributing this to excessive crimping with my RCBS dies, my fault though not theirs.

So, will the collet type pullers do this faster than my hammer-type, which I can barely get to work (can't really work at all actually) or should I chuck the 100 loaded rounds and just buy new brass?

Also, should I invest in Lee factory crimp dies, or are they just as finicky as my RCBS ones? I have a feeling I have this crimp thing all wrong and want something more foolproof.
 
If I get the Lee factory crimp, will it uncrimp the rounds enough to chamber. Upon inspection of my cases, it looks like the case is dug into the lead a little bit, and you can't really see the top of the case (case mouth?).
 
It sounds like the cases have bulged a bit. As you cycle them through the Lee die, the cases will be 'tweaked' back to spec.
I bought some private manufacture ammo that suffered from this. A trip through the die and all was good.

A quote from Lee.
Lee Carbide Factory Crimp Die

A carbide sizer sizes the cartridge while it is being crimped so every round will positvely chamber freely with factory like dependability. The adjustig screw quickly and easily sets the desired amount of crimp. It is impossible to buckle the case as with a conventional bullet seating die. Trim length is not critical so this extra operation takes less time than it would if cases were trimmed and chamfered. Revolver dies roll crimp with no limit as to the amount. A perfect taper crimp is applied to auto-loader rounds. The crimper cannot be misadjusted to make a case mouth too small to properly head-space. A firm crimp is essential for dependable and accurate ammunition. It eliminates the problems of poor ignition of slow burning magnum powders.

Take the sizer die, and unscrew the deprimer pin. This will allow you
to gently do a bubba factory crimp. I did it on mine, and they shot well.
make sure you mic the hell of of them thought.

I have done this and it works fine. Fix up what you've got on hand, and spend 18$ and buy a lee factory crimp die. works wonders....
 
+2 on the Lee Factory Crimp die.

I had to run an old batch of 1000 9mm reloads that were loaded with a steel sizer that was a bit on the large size. One of my guns has a tight chamber so chambering was very tight.

Ran the loaded cartridges through a Lee Factory Crimp die and all worked perfectly.

Will get the factory crimp die, will try using my RCBS resizer w/out the decapper, but what the heck does 'mic the hell out of them' mean?

measure the cases to make sure you've ironed them out. Mic=use a micrometer on them. If you have a good feel, a vernier is plenty accurate enough...
 
Happydude,

You need to have a dial caliper, get the dial type, works great. That way
you can alway's verify your reload dimensions prior to going whole hog.

I have an RCBS caliper, use it for measuring overall length. My rounds slipped in the disasembled barrel just fine, but wouldn't chamber. I'll see if I can measure them against a factory round and see where I went wrong.

Oh, and I hope to have them ready for Wednesday night, hope it's still going ahead.

if it chambers in the barrel but won't cycle through the action it would seem to indicate a overall length problem. Your manuel should specify a max OAL for the bullet your using, check to see you aren't too long or short.
