I only have one set of Dillon dies because they don't come with a belling die. I load blaster ammo on my 550 but all my precision loading is done on an RCBS Rock Chucker so if you want to move the dies to another press, you'll bave to buy an extra die.

The Lee dies I have are a little too short for the 550b. The RCBS and Hornady dies work like a champ.

I don't know how old your dies are but any newer Lee dies are plenty long for the 550.

I use Lee dies on a 550b for 380, 9mm, 40, 45 and .223. The Lee dies work well and are plenty long enough. I also use the Lee locknut with its "O" ring and have not had a problem on the toolheads, although space is a bit tight. A good adjustable wrench on the bench is all that is needed.

All of my dies are old with the exception my 10/40 die set (Hornady). The Lee .223 dies I have only engage the lock-ring by about 1 1/2 or two threads.

Should I get the dillon dies or would it be OK to save some money and use lee dies?

Any problem with using the lee dies in the dillon 550b?

i use dillon, rcbs and hornady dies in mine. they all work great, just some die sets may cause you a little extra work. the lees should work also, though i have never used lee.
good luck and enjoy what will be your favorite pastime.

I buy the Dillion dies myself. The Dillon seating die is "designed" to seat the bullet straight. That's it's main goal. It will seat your bullet absolutely correct. They don't try to crimp in the seating process. The Dillon crimping die does the crimping . Dillon does not design a die to seat and crimp in the same operation. Dillion does not think it is a sound reloading for a die to seat and crimp in the same operation.

That said, I will exchange the dillion sizing die with a Lee sizing die to size the brass down lower on .40 that has been shot in glock pistols. The Lee die will get the Glock Bludge out of the brass when the dillion will not.

I run Lee, RCBS, and one set of Redding .300 Win Mag. All work perfectly fine. I'm loading 9, .40, .45, 10mm, .223, 357 SIG, and .300. I have some Lee FCD as well, and like the separate crimp step.

I use all Lee dies on my 550, no problems.

You "woke up" an almost 2 year old thread for this?
1) I imagine he's already had his question answered.
2) These type of questions come up often, but I don't think you really helped anybody here.

But thanks for playing.

I wondered why myself, but considering that this question pops up a couple of times each month.....
