I just started to load 45 and i am having trouble with the rounds chambering, seems like a small ridge is forming from the bullet being pressed in the case. did anyone else ever do this and what do you think i should do. I load 9mm and 357 with no propblem
 
Are you expanding the case mouth too much in order to insert the bullet...and/or are you not putting enough crimp on the bullet?

What bullets are you using and whats the OAL?
 
Make sure your bullet is not oversized (.453 or larger) and use a taper crimp die. Adjust the crimp until the cartridge drops into the chamber with a "clunk" when it stops on the case mouth. test 5 or 10 to make sure they are the same. Try the same with other brands of brass and see if they all work with that setting.
Carry on!

Yep - Like others have implied, just put a heavier taper crimp on it. You can test fit using barrel (removed from the receiver of course). Try dropping a few newly-crimped bullets into the chamber - if you turn the barrel up-side down, they should just drop out.

Forty-five is picky that way. don't be afraid to crimp.....
 
I got the best results myself by reducing the flare rather than increasing the crimp. Either way will get you there though...

I just found that relying on the crimp, it was really only crimping at the top of the case. The result if the crimp wasn't tight enough was bullet setback. :eek: Since I backed the flare off, I barely need any crimp at all, just enough to straighten the case out. No more setback either.

This works more consistantly for me and I figure the less flaring and crimping you do will extend your case life. YMMV.

The less you "work" your brass, regardless of caliber, the longer your case life will be. "Work hardening" leads directly to splits/cracks and case failure.
 
You've probably read your lee instructions exactly flared your cases too much. I did this starting out. Crank your expander out so it is not touching the case. Then screw it in till it is just touching the case when fully extended. Then turn the expander a quarter turn. Try to expand one case and seat the bullet. If the bullet wont go in at all do it again. Keep repeating the experiment untill the bullet will barely go into the case. This is the right setting.
 
on the orig batch that gave trouble i did not use the flare die at all and i did use the factory crimp die. I went out last night to test some other methods and did use the flare die and it seems to help with letting the bullet slid in with out case distortion. the lead size is .451 by frontier cmj 230gr rn.

the first batch used the roll crimp and accoring to my local group i almost had to much roll crimp.

thanks for the info i am going to try some more ways to do it and see what happens
