Couldn't have said it better then JBledsoe!!!!!!!!!!!!!!!!!!!!
Now, just so you all know, lee makes two different types of the "factory crimp die" and while there are good reports from some quarters about the collet type, IF you are using cast bullets, AVOID the type with the carbide ring in the die mouth!!!!!!!!!!!!
One of those pieces of junk gave me no end of problems which took me days to figure out and solve.
The carbide type is made for the straight wall cartridges such as the .38/.357, .40SS&W, .45acp and .44 etc.
The problem that occurred in my case was with a .45acp "fcd" and after repeated failures to feed where the cartridge would not allow the slide to go to battery, I finally found that the hooky die was forcing bullet metal forward and forming a tiny lead ring around the case mouth which in effect made the head to case mouth measurement overly long.
Now, from my experience finding that this type of die allowed cast bullet loads to function in a friends .40S&W, the PROPER solution would have been to use a slightly smaller sizer/luber die rather then allowing the "fcd" to distort the cast bullet.
Looking at it in another way, it makes absolutely NO SENSE to strive for proper cast bullet to bore fit and then have some hooky die force the bullet to undersize!
I fully understand that I am talking about TWO different dies here, but the point is they both are sold under the heading of "Factory Crimp Die" and you may, as I did, get caught up in some lee hype.
Use the collet type "fcd" if you must, but I'll firmly stand by my earlier comment about PROPER DIE ADJUSTMENT being all that is needed for highly successful Hand loading. That being the case in well over 90% of folks handloading situations!
So put money in lee's pocket if you must, but most times it is a wasted expense better put toward primers and powder.
As per lee's stupid non-locking "lock ring", just how stupid can they be. It is however good for some of the other companies with the sales of real and locking lock rings. Yes, I have been there and done that also. Now I am just a VERY selective buy of lee products!
Hate me and my post is you wish, but I am just too old and been handloading for too many years to abide junk.
I'll GLADLY pay the little extra for quality!
