I have a Dillon 550 just would like to ask every one out there what brand dies might work best for me on this machine.
MO please help!!! what would you use?
Thanks in advance.

I've got a Dillon RL550B and don't use it for the 5.7x28. This caliber is not particularily well suited to progressive reloaders. I would be concerned with using the Dillon loader throwing the kind of accurate powder charges you need with the 550. Also, a hand priming tool is much better suited to seating the 5.7's primers, which need a good solid seat (pockets tend to be a little looser than most calibers).

Also, the 5.7x28 cases tend to stretch significantly upon firing, and trimming is a step best done between the resize/deprime and priming operations.

I handload for this caliber using an old RCBS Rock Chucker single stage press, with resizing / depriming using Hornady dies. I trim using a cordless drill and Lee collet trimmer, then prime with an RCBS Auto Prime. I throw my powders with a RCBS single throw powder measure and then seat bullets on the Rock Chucker with the Hornady seating die. I weigh every 10th round on a digital scale.

It only takes a couple of hours to turn out enough ammo to shoot in a trip to the range. I'd recommend the single stage loading process.

thanks for the info UltraFudd I realy apriciate this info.

you said "a hand priming tool is much better suited to seating the 5.7's primers, which need a good solid seat (pockets tend to be a little looser than most calibers)."

will the dillon 550 not put the primers in right?

would you consider ever using the 550 for subsonic loads only?

I want to reload sub sonic loads only for a supresed PS90 SBR.

again thanks again in advance

The problem with the 550, or any Dillon press for that matter, is that there is no shell plate or conversion kit for the presses. Only RCBS and the Hornady LnL are capable of progressive reloading the 5.7x28.

I personally use a new Rock Chucker (well its new age wise, maybe 3 years, but I've reloaded several hundred thousand on it and its nearly time to send it back for refubishment), an RCBS handprime tool, Lee OAL length guage and trimmer, manually charge the cases, and weigh every 10th charge with an ancient Lyman/Ohaus M-5 balance beam scale.

Doing batch reloading I am able to load 2k in a day. Its a long day, but I can do it.

When it comes to trimming there are a couple of ways to do it. For plinking loads I will use a modified Lyman accutrim and trim the brass to 1.128" which gives me two firings before I have to trim it again. For my more important and test loads, I use the Lee and trim to 1.135" and trim between every firing.

Anyway, I think my point was that unless you can find an aftermarket conversion for the 550, you are out of luck. There was one machinist who made some, but he made only one run. Herstal, a member here and who is also a machinist, is currently working on a batch. When he finishes them I will have one to test and then I will write a review on it. Be aware, custom conversions are never inexpensive, and never made in large numbers.

If you have any more specific questions, feel free to ask :)

thanks for the info MO :)

I will most liklely go that rought (rock chucker) in the mean time

My reloading rep for the dillon is having a machine shop working on either a shell plate that will hold the shell or a jig I will have to ask him at a fairly reasonable price will let you know.

however one more Question.

(assuming that I soon might have the shell plate figured out. )

I was just wondering what brand dies would work for the on the top end the of the 550. would like not to buy two different kinds mayby one will work for both?

also I am not looking to do high power loads just some subsonic loads only.

You may be able to use the RCBS or any other for that matter.. If its too short, put the lock ring on the bottom side of the press instead of the top. This shouldn't affect anything. This is a trick of those who prefer Lee dies in the Dillon press.

The reason I mentioned priming issues with the RL550 is that you have to very carefully adjust the shellplate so that it will still turn, but not so loose that the primer does not seat all the way into the pocket. My experience with the 550 is that the 550 does not seat primers as deep or firmly as a hand priming tool. Priming is best done by "feel", and IMHO, a hand priming tool gives the best feel when performing the operation.

Subsonic loads would be much better from the standpoint of not approaching a maximum charge. I found that my 550 is usually accurate to within +/- 0.2 grains if I'm throwing pistol charges in the 5 to 10 grain range and I don't get a stuck case where the press gets bumped hard. Anytime you're working close to maximum, or with a hot load and you bump / bang, or jiggle a progressive press to get a press cycle, you'd better pull that casing and check what weight charge got thrown, because there's a good chance that you could have a .4 to .6 gr variation. With the 5.7, that's enough to make your day exciting at the range.

I don't know. I don't know anyone who has one at the moment, and I'm still waiting for my shell plate to come in from Hornady (special order only, 30-45 days).

I wonder if anyone can recommend a book on reloading. Being a beginner at this stage, I have found that dies for 5.7x28 from RCBS and Hornady. I am not sure what to buy. I also want to reload 9 and 10 mm auto.
