After I complete loading, .45 ACP, I drop every cartridge into a go/nogo gage. I got a rejct rate of 20% in this last batch. Typically for diameter as indicated by a bulge indicating that the bullet is either out of spec or loaded cocked. I run the completed cartridge thru the resizer die ( obviously with the decapper removed!)
The solves the fit problem.
Should I recrimp them also?

I am loading 200 gn SWC lead.

No...

Load them correctly the first time...

Carp, I suspect your problem is with how you crimp them to begin with. What sort of crimp are you using?

What you are doing by running the loaded round back thru the sizing die is seriously UNDER sizing the bullet.

By the way, forget the go/no go die. What is the rejection rate from your pistol?

I am using the standard Crimp die that comes with the Lyman 3-die set. I believe that is a roll crimp die.
I don't think the crimp die is the problem. It seems like some of the bullets actually seat a little cocked to one side.
I am not using a seperate go/nogo. I remove the barrel from the gun and use it. It was just to much to type in the original post. That is what the 20% is based on. there doesn't seem to be any middle ground, ie it almost fits. The cartridge either drops in easily or only gets in about 1/2 way.
I am using a RCBS Rockchucker and single staging the loading. I set the bullets in the cartridge and try to get the as straight as possible before pressing and crimping. I have considering opening the case mouth a bit more to get a better head start.

I have had good performance by seating the bullets and crimping in a seperate operation. Crimp with a .45 Auto, Lee Factory Crimp Die (it is a iaper crimp) and do not crimp too much. It also sizes any oversize cartridges to "maximum cartridge dimensions" (it has a carbide sizing "ring"). No need to check the loaded cartridged after crimping, they are "right" and do not cause the bullet to be undersize. This is the same number of operations as seating the bullet and crimping in one operation and then checking the loaded cartridgd in a go/no go gage or pistol barrel chamber. It is faster for me and allows the use of cast bullets (such as Lee "tumble lube" designs), with complete reliability and without any seperate sizing of the bullet at all. You can also "correct" your "reject" cartridges with the .45 Auto "Lee Factor Crimp Die". I think you will like it if you try it.

Two other things, if the bullets are not being seated "straight" in the cases, you might check your seating punch in the seating/crimping die to make sure it is compatable with the bullet style and "nose" shape that you are using. You might also may want to adjust the expander plug to be sure that you are getting enough "bell" or expansition of the case mouth to get the bullet started in the case correctly and uniformally.

I think Pecos45 has the answer to your problem. Check and make sure you are not over crimping your ammo. I get a few cases with slight bulges from the bullet but have never had one that refused to chamber.
The proper crimp for the 45acp is a taper crimp BTW. If your die is roll crimp find a taper crimp die or - I don`t believe in them - a Lee factory crimp die. I will hear about it but I feel the Lee die fixes a problem that shouldn`t exist to start with and anything that sizes the bullet can`t be good. JMO others swear by them........

Carp - I'm not crazy about Lymann dies. I've had some bad experiences with them but anyhow, if that's what you have....

I agree with the notion of belling the case mouth a bit more but I think a lee taper crimp die will suffice.
