+1 on the 550. The 450 does not have a removable tool head. I agree with Dukerdog. Get Dillon to tune that machine up and you will have a very nice second machine. I gave my 550 to my son and bought a 650 from Brian. I love the 650 but I miss the 550 for loading rifle and some of the more esoteric cartridges that I shoot.

I put mine back on the 550 when I gave it to my son and keep the roller handle for my new 650. I guess that makes me a bad father... As soon as the 650 arrives, I will have another one....

FWIW. I am a BIG fan of the Lee FCD. My first use has been on my .357mag cartridges. They get a tight roll crimp to improve consistency. Before the Lee FCD, I was getting a slight bulge below the crimp causing the cartridge to not want to chamber in my lever action rifle. The Lee FCD has totally solved the problem. If there is no bulge, it does nothing. If there is a bulge, it irons it out as the sizing ring slides up and comes up off the case. Since they don't make a Redding grx die or a Lee Bulge Buster kit for the 9mm, I just ordered another Lee FCD in 9mm. I intend to try it in an attempt to address the bulge near the base of the case on some of the range pick up brass that ends up mixed in with my brass. The bulge that I am speaking of is the one caused by the cartridge being fired in an unsupported chamber or an oversize chamber. I have had good success with the standard Lee sizing die in .40s&w in dealing with the guppy belly in some of the brass. My Dillon die just has a bit too much taper in the mouth of the carbide to get the last bit of bulge in the .40 cases. Same with the Dillon dies in 9mm. Not having the large mouth on the dies has slowed down my production rate somewhat. That's why I am going to try the Lee FCD die in 9mm, along with the Dillon Sizing die in station #1. If it works, I will try it on the .40. The other great success I have had with the Lee FCD is in loading .308 ammo on my Dillon 550 for use in my son's FAL semi-automatic rifle. The rifle crimp die is totally different than the pistol die. The rifle die has a collet that squeezes the crimp into the case with little or no down pressure on the shoulder of the case. After going to the Lee FCD in the .308, every case passes the chamber check. No more problems....

I keep a small stainless steel brush handy and when the primer punch starts looking cruddy, I run over it with a few strokes of the brush. That seems to cure any denting problems that occur. FWIW
