mdi, I totally agree!

opos, When loading on my Rockchucker, I've always use dual-function crimp & seater dies in separate functions .... seat a batch of bullets then go back and crimp all the cases. Like you, I don't like to see the bullet move deeper as it is being crimped ... it tends to shave and distort bullets, which degrades accuracy. All brands of crimp/seating dies (not just Lee) tend to have issues when both functions are done with one pull of the handle. My solution is simple .... I load nearly all my handgun ammo on my Dillon RL550 using Dillon dies, which have a separate seater only die and a crimp only die.

If you follow the procedure I posted above in post #3 (separate bullet seating and crimp function) I can assure you your ammo will come out better. Of course it adds another handle pull for each cartridge so it takes more time. Hope that answered your question.

Bingo! when I don't use a FCD on jacketed bullets I do the same with the seater/crimp on my Lee Classic Turret press...I don't mind the extra handle pull..got nothing better to do and if I go inside I get a "job" to do..so I stay outside.

Many reloaders seat and crimp in the same operation, but the adjustments need to be right on. Too much crimp, and the bullet is still moving when the crimp is applied tightly to the moving bullet, the case gets bulged. Sometimes there are large variations with OAL/seating depth if the crimp ending and bullet movement aren't coordinated. When I started reloading, I had a bit of a hard time coordinating the crimp and bullet depth, so I separated the steps. That was prolly 25 years ago and it's still works for me...

As Iowegean stated, Lead bullets should be at least .001 over bore diameter, and the Lee FCD for pistol cartridges squeezes your lead bullet down to the diameter of jacketed bullets. I screwed my FCD into my old cast iron Lyman press and with a punch and hammer removed the post sizing ring and "fixed" the problem.
