Re: Looking for some experience.
I went with the Dillon 550 to get started in reloading for 9mm, .223 and .308/.30-06. May be a bit more than Lee or RCBS, but excellent customer service and very well engineered.
Their 650 press has auto indexing, but that makes it a hassle to change calibers, so not really worth that route unless you are going to be making at least a 1000 or more of one round before you change to another caliber.
Any brand of carbide dies for the 9mm. Dillon says they have a bigger entry radius on theirs to make initial alignment less critical, but who knows.
For rifle dies, make sure you get or can change the "ball" on the decapping rod to a carbide one. Makes it easier to get down the neck. Standard on Dillon rifle dies, not on Hornady, and don't know it is available for that brand. Available for RCBS dies.
