Dillon press questions

[Collo Rosso]

Thinking about a Dillon 550b this Christmas and have a few questions for owners.

550b will take any 7/8" dies and I have RCBS and one Lyman set for all my calibers. Is there any reason to switch to Dillon dies? Anybody using a 550b with competitive dies? Work well?

What do you do for powder check? Can you see the powder in the case? I load from a RCBS uniflow with cases in a sized loading block. Easy to run your eyes down the rows and spot a double or no charge.

Hows the primer feed system? Any brands it doesn't work well with? Good feel? High primers?

Was thinking the same thing only other questions is the power feed how well do's it work with different powders

Morning. I have had a 550B for almost 20 years, but I have been unable to use it for about 9 years due to accident injuries. I am just getting back to loading handgun ammo with it. That being said ...

I have recycled my reloading dies, using my RCBS, Hornady, and Lyman dies on my Dillon, there is no reason to buy new dies, they work quite well. I tried reloading rifle ammo on my Dillon when I shot service rifle, I didn't like the accuracy, so I load my rifle ammo on a single stage press. My Dillon is used only for pistol ammo, and I use only carbide dies. I have used CCI, Federal, and Remington primers,and have never had a problem, never a high primer unless I was not paying attention to what I was doing. With respect to the powder charger, if I don't leave powder in the thrower over night, I don't have to worry about powder clumping or caking up, so powder always flows freely. If I pay attention, and remember to advance the shell plate, I never have to worry about a double charge.

Bottom line, if you pay attention to what you are doing, and your primer and powder supply, you produce a perfect round with every throw of the lever.

Re: powders. I have had no problems with either flake or ball powder. I have had problems using extruded stick powder such as IMR4895 and IMP4064.

Your existing dies would work just fine with 550B. I've used CCI, Federal, Remington, S&B and Tula primers - never had any issues with any of those. For powder check I have goose neck LED light installed in the center of the toolhead and just do visual inspection. You can buy an adapter and still use your uniflow with 550b if you prefer it. I didn't use competition dies so can't comment on that. What may affect your competition loads is the fact that toolhead has a little play (intentional). Good luck with your purchase.

I have 2 550b. I bought one in the early 80s. I use Dillon dies because I like to crimp in the last stage. Other brands of dies work fine but I order a crimp die for the final crimp. No problem with any powder. If you have a problem with a 550 that is what the adjustments are for. Clean brass is a +. I bought a lot of stuff in garage sales. A lot of people have no ideal what they are selling. Even most used reloading items have a lifetime warranty. When you see blue=Dillon--red=Hornady--orange=Lyman--RCBS=green--Even if you dont need it & cheap snatch it up. If you are getting into reloading you will need it later. Lead melting pots are some peoples junk when their spouse passes away. I gave $300 at one place for $1200 worth of their junk. If reloading equipment is for sale- -DO YOU STILL HAVE THE GUNS?

I use a mix of dies on my 550 & 650, works fine. RCBS dies, Hornady dies, even a Lee set, works fine.

I've had my 450 over 40 years and have upgraded it to a 550 w/o the toolbar. Mostly RCBS dies along with Dillon, Hornady, and Forster. Not the best accurate powder dispensing for rifle powders, but I don't dump those anyway skipping stage 2.

I could have written Post No. 3 word for word. I had a Dillon 550B and a Dillon 550. I was set up with the older solid head 550 for pistol cartridges, so tried loading .223R looking for accurate loads to be used in rifle competition on the 550B. I wasn't satisfied with the 550B's removable die head because I could see it flexing while in use. I figured I wasn't getting as accurate of loading as could be. I went to my RCBS Rock Chucker and loaded 100 rounds using the same components as I did on the 550B. I got much better accuracy by making the change. So. I switched the pistol loading operation to the 550B and the rifle loading operation to the fixed head 550. The accuracy of the loads came back to all but the same as the loads done singularly by using the RCBS Rock Chucker. Because of my advanced age and the declining amount of rifle ammo I was shooting, I sold the 550B, kept the 550 and added a Redding T-7. I have been very happy with the results.......

I think that Dillon products are the top of the line for their intended purposes. I have never had a double charge, nor a skipped powder charge. I have caused errors in loading thru my own actions. After one is familiar with the Dillon Progressives operator caused bobbles are easily corrected. ...............

Thanks for the replies. I have a Redding T-7 now that works fine, but the 4 pulls of the lever for a cartridge is starting to get to me. I have a torn rotor cuff in each shoulder and after so many pulls I start to feel it.
I'm shooting more and more lately with bowling pin and IDPA matches and keep finding myself with little time to reload. Add in my son and pistol ammo seems to disappear. It's looking like a progressive would be good for me.
Probably keep the T-7 for rifle as I don't shoot much in those calibers.

To the OP:

If you are looking at loading one or two cartridges, I would suggest that you might consider the Dillon Square Deal B. If you are loading more than two, look at the 550B.

My 550B is currently set up to load 38 Special, 357 Magnum, and 45 ACP. My next purchase will be a conversion kit for 9mm Luger. Since I have the conversion kit for 223 Remington, I will have the flexibility to add 380 ACP. 41 Magnum will be done on the RCBS press.

I can not speak for certain, but I think that my problem with loading rifle cartridges was due to two problems: not full length resizing separately, and using stick powder. I am contemplating full length sizing a hundred or so throw away 223 cases, then doing a production run of 223 Remington with pre-sized cases using AA2520 and 55gr FMJ for my CQB rifle.

It's best to use Dillon dies. The resizer is tapered for easier entry than dies for a manual press, and the seating and crimping dies are separate. You need a special expander/funnel for the powder stage, so an RCBS (or other) expansion die sits in the box.

You can use the RCBS seating/crimping die alone, but you get better results with much less force if you purchase a separate crimping die. I recommend the Redding die.

I stand to the left and observe the powder drop before proceeding. If interrupted, I always turn the table to place an empty cartridge (or no cartridge) under the powder funnel. I load standard magnum and rifle cartridges, which will overflow if double-filled, unlike many target loads. I don't even own any Bullseye.

I use a Inline Fabrication skylight on my 550. It sits in the toolhead and throws a very nice light down into the interior of the press. Very easy to eyeball your powder throw on every case.

I also use this light on my 550B. I made a home made mirror attachment using a telescoping mirror to see inside the case for powder level. This is what I am going to buy soon to replace my contraption. The Original Powder Mirror

I thought this is included with the caliber conversion?

I've already separated seat and crimp with semi-auto pistol rounds. I was tearing the coating on powder coated bullets, but I'm not so sure it wasn't the cheap brand of powder coated (not Hi-tek) bullets I was using.

The 550 is a fine press and has a lot of loyal users, but if you can afford it, especially if you plan to shoot a lot, consider the 650XL. I have literally reloaded 1,000 45 acp's in an hour, not counting prep time of filling primer tubes. That's an extreme example, and one that I only did to see if it was possible, but you get the idea. A more realistic number is 500 to 600 an hour. After you've used the press for several decades and get enough ammo made to last to your dying day, you can sell it for more than you paid for it, so in the long term, it won't cost you anything.

Agree. After a lot of consideration between the 550 & 650, I went the 650 route. No regrets.

you get a powder funnel with each conversion set. You only het on tool head & one powder thru die, so having addl tool heads with powder thru dies is pretty much mandatory.

I take it the powder funnel goes in the powder thru die. I'm guessing the funnel also does the belling as it comes in a caliber conversion kit. I've figured out I'll spend a small ransom on tool heads and conversion kits when I order the press!

I found a great thread on this forum about 4 years ago discussing the 550b vs XL650. The 550b was the favorite for 500 rounds or so a session and lots of caliber changes. That would be me.

Dillon 550B

Isotherms have said I use my 550B only for pistol cartridge reloading or bulk rifle cartridge reloading for my class III's. The Dillon powder measure just doesn't throw consistent enough loads even with ball powder like W748 to produce precision rounds for my target rifles. Stick powders are especially a problem with the Dillon powder measure. For precision rifle loads I use my Rockchucker and an RCBS ChargeMaster to dispense powder and check every 20th round on an Ohaus 1010 scale.
Any quality dies work fine in my 550B.
