I recently stared reloading for my 1911. I purchased some Win 230 grain JHP and have had a helluva time reloading them. My dies are an RCBS carbide 3-die set(seating die also performs a taper crimp). I have made sure I have the correct seating plug in. I am belling my cases, but not sure if too little or too much. The steps I take to seat and crimp are as follows:

1. I run a charged case to the top of the stroke and screw the die down until I feel the die touch the case(on thing I have noticed with this process that is unlike when I reload for 9mm is that with the 9 I feel the die stop dead in its tracks when it touches the case. With the 45, the die will keep screwing down).

2. I then lower the case, insert the bullet and run it back to the top of the stroke. I then start screwing down the plug a little at a time while measuring until I get my COAL correct.

3. Then I unplug the plug several turns and start screwing down the die a little at a time and checking my crimp until I am satisfied.

4. Once I am satisfied with the crimp, I then screw down my plug and now I am ready to seat and crimp in one motion. However, when I run the next case and bullet into the die, the cone of the bullet is getting smashed and the wall of the case is buckling.

I loaded about 20 of the same bullets a few weeks ago w/no trouble, now all this crap starts today, so I don't know what the hell I am doing wrong. I can say that it has gotten pretty cold since the previous 20 rounds (I am guessing it's around 40 - 45F in my garage).

Any help would be greatly appreciated. Thanks.
