Most people will tell you what their using is the best. I had a Dillon RL 550B 20 years ago and sold it when I got out of bullseye shooting. About 4 years ago I picked up a Hornady LNL autoprogressive and I like it better then my Dillon. Right now you get 1,000 bullets from Hornady for buying the LNL so in the end your paying less then $200 for the unit. If you compare apples to apples Dillon RL 650 which is a autoprogressive and not the RL 550 your paying alot more for the Dillon. Hornady also gives you a no BS warranty like Dillon. If you plan on knocking out alot of pistol rounds both machines will do fine, if your precision reloading stick with a single station press like the RCBS Rockcrusher.
Remember what rebelace said? he was not inpressed with his friends 650 Dillon. HMB your right about the Star, I had one but sold it. Finding parts for one is just as hard. I still have 2 Star lube sizers.
hmb, You might have misunderstood my post about the lube sizers. They are for sizing and lubing lead cast bullets. 20 years ago I sold my Star press in 38 special to get a Dillon RL550 That was a mistake. My 1 lube sizer is tricked out with a heated base, and air feed for pressurizing the lube. This sizer can run at 2,000 an hour. Put a bucket under it and let them fall.
I loaded a lot of ammo on a RCBS rocker chucker. Never broke any part of that tool and still use that 40 year old press for small batches of rifle ammo. This is an okay way to go if you only need a box or two of hunting ammo at a time. If you are shooting any kind of competitive game you will need a progressive loader. IMO, the Dillon 550 is your best bet there for many reasons, a distant second would be Hornady's progressive.
At Quantico (more years ago than I like to admit) the Marines loaded up rifle match ammo on the Bonanza CO-AX press which is a pretty fair endorsement. When I shot High Power Rifle and 1000 yard matches competitively as a civilian(again more years ago than I like to admit) I used a RCBS Rockchucker. It still loads great ammo and has had zero breakage or repairs needed in 37 years.
For a progressive I like Dillon but had no problems with my old Hornady Projector either. The powder dump was a little complex on both it and the RCBS but worked well after adjusted. My RCBS pro-2000 used the APS priming system which when it worked was OK but was easily knocked out of alignment and required a clear space behind the press for the empty primer strip to move.
My one problem with the Co-Ax - it was a very effective press, very fast to change dies and very little issue about shellholders (unless you load a caliber which requires the second set of jaws, which I did), is that I learned to load on a Rockchucker. So I learned the case shuffle, where you pick up the new case between left thumb and forefinger, and take the last one out of the press with left forfinger and middle finger (it's harder to describe than do). This minimizes the motion involved. But it requires using the right hand on the press handle and almost madates sitting directly in front of the press. The Co-Ax's handle comes down along the centerline of the press, so I had to sit off to the right and then my arms crossed with every handle stroke. Very awkward. So I sold it and replaced it with a Redding Boss, which did everything I needed it to do at the time and was comfortable as well.
That was before I got my first 650. Boyoboy, what that an eyeopener for production speed.
