I am loading my 45's using a single stage press (oh the agony) and am seeking feedback about putting a factory crimp using the Lee die. I only use jacketed bullets. I am curious as to the benefits of using the factory crimp or not. Thanks.

I use a Lee FCD for .45ACP. All I can say is that it works to my satisfaction. I don't know whether it works better or not compared to other taper crimp dies.

I've never used one but one of my freinds ran some tests w/ one. It can work it can also reduce neck tension if adjusted wrong. I've managed 100s of 1000s of rounds ove the years w/ std. taper crimp dies from Dillon, RCBS, etc.

I have loaded with and without the extra crimp. Without the extra crimp means 500 less pulls on the ram!

I like it, but am not sure it is necessary if you have a properly adjusted crimp in the first place which supports the folks who say it is a crutch for poor set up / adjustment. That said, I notice a little difference and sometimes use it.... I have no idea why other than I like the general idea.

I also think you can overdo it and mash things. Fred's comment about neck tension makes some sense - if you set up the Lee FCD such that you over crimp, the theory is the brass is more elastic than the lead. Thus, the brass rebounds and the lead just flows away. I'm not sure that's true but I definitely would go light on the crimp and enjoy the full legnth resize.

I probably would not bother with a single stage set up properly to resize and to crimp.

It is, more so withlead or plated than jacketed, but we experimented w/ it when my buddy got his LNL up & running. If you screw the die down tojust taper crimo, it will owrk, screw it down to size the entire case, it causes less nect tension, resizes the lead bullet which causes poor accuracy & add'l. leading w/ lead bullets. It is a gimick for fixing improper die setup. It will catch the occasional over sized round, but so will a case gage.

Fred, what did you do to measure neck tension? Maybe a collet puller with a pull gauge? I'd be curious to try it myself because I have a bundle of LRN bullets to load. Thx
