Re: Dillon 550

I currently have an RCBS rockchucker kit which has served me well for a couple thousand rounds over the past 2 years. However, I'm getting to the point where the single stage is just too slow for my .223 and 9mm loads (AR/3 gun stuff - not precision handloads by any means). I also do precision loads for .308 (using the TresMon guide with everything except for annealing, neck turning and checking for run out - a concentricity gauge will probably be in the short future).
I have no doubt I'll be able to churn out a ton of .223 and 9mm that will more than meet my expectations for that type of shooting (3 gun here is well within 100m - no long shots for .223). However, I was curious as to how good of loads I can get if I were to set up a Dillon 550 for .308 as well. I know the major challenges I'll be facing when upgrading from the single stage to the progressive are the deviations in powder throwing and sacrificing a little on consistent bullet seating depth. I shoot an AICS with a R700P factory action/barrel, so I've resorted to mag length loading at 2.810" versus ogive seating depth - no need for benchrest style QA/QC as my chamber tolerances are too far on the safe side and I shoot 99% steel (lucked out with Fort Campbell having a phenomenal POW range as far as posts go). If I use the Dillon 550 for resizing, do my part with regard to case prep and sorting, then go back to priming, powder throwing and bullet seating with the 550 will I experience results that are not too far off of the single stage method where every charge is weighed and I check each COAL? Or in your experience would I be better off just keeping the RCBS kit for my .308 loads?
Thanks in advance. </div></div>
Hey Cardiac!
Hey I have my vintage original Dillon that has been updated to RL550B specs dedicated to reload for loading high precision .308Win rounds. It sounds crazy but having essentially four presses in one is hard to beat. I use a Redding Competition Bushing Neck die in the first position setup to decap, perform the first and largest neck size and prime. In the second position in place of the powder measure I have a Redding Type S Match Bushing/Full Length sizing die used to set the shoulder where I need it for particular rifles I reload for and to put the last gentle squeeze on the neck. In the third position I have a Redding Instant Comparator to verify the base to should DL and/or base to ogive height and in the last position I have a Redding Competition Bullet seater.
Here is what I do with fired brass that has previously been primer pocket uniformed and flash hole deburred abd uniformed. I'm switching over to ultrasonic but this is has until now been the routine. More than likely all that will change is that I'll decap the fired brass then dump them in the ultrasonic cleaner then off to the frist station of the Dillon with no decap performed.
My loading work flow might sound sort of crazy but works pretty well for no turn hand loads. Fired brass is dumped straight into a vibe cleaner. The cleaned and inspected brass gets checked for length, if the case needs trimming I set it aside for trimming and deburring then slipstream them back into the brass being loaded. If the case is O.K. the brass is then put into the first Dillon RL550B station where it is decapped, neck sized and primed. I like Imperial wax as a lube, great stuff!
Next the case goes to the Dillon's second station where a Redding Type S Match Bushing/FL sizing die full length sizes and final neck sizes the case. Then I index the case to the Redding instant comparator for a quick check of the shoulder height. From the comparator station I pull the cases and put them into a loading block for powder charging.
I use a Hornady electronic powder dispenser. I powder charge the cases and return them to the third station (where I have setup the Redding Instant comparator for ogive measurement) and then index them to the Redding Competition Bullet seater for the appropriate projectile. From there I reverse index the loaded round back to the Redding Instant Indicator and confirm ogive height and pull the loaded round out of the press and back to another loading block waiting for a quick wipe and final visual inspection before they go into a marked case with the round information.
It seems like a lot of work but I know that every loaded round is perfectly sized for the headspace of my rifle and the bullet will have the same jump to the lands. This means my brass will grow minimally and that the accurately and consistently scaled powder charge will produce consistent pressure due to precise case length, consistent bullet seating depth and the consistent case volume they produce. Also the case neck tension on the bullet is consistent as is bullet jump. All of these things make for repeatable projectile placement once you find the best node and jump for your rifle chamber and bullet.
It's not exactly the way the manual says to do it but you would be amazed at how well a basically off the shelf rifle can be made to shoot by hand-loading for that particular rifle using a Dillion progressive press.
Oh yeah, it works like crazy for handloading for pistols too. Just pop out the two pins and swap out the tool head with your pistol setup and you can be back in business loading pistol ammo in minutes. The Dillon is pretty fast and loads pistol ammo very well too.
HTH!
Edit: Another thought, mount the Rock Chucker and install a Lee universal decaping die to quickly decap fired cases before ultrasonic cleaning.
