Hmmmm... Another one of these threads
Let's have a practical look at loading .223...
The issues we all have with volume loading are easily overcome with time and/or money, when your faced with reloading 4000+ rounds a year think about this....
#1 swageing primer pockets:
95% of the .223 brass I have put my hands on has a crimped primer, infact I sell most of my commercial brass and buy Mil just for the simple reason of knowing what to expect with every piece!
There are many options for getting rid of that pesky crimp
drill and chamfer tool, RCBS swager die, sharp knife etc etc
The common thread with all options is time, every time you add another step where you handle all your cases your adding time... I can run a single case thru my dillon super swager in 5 seconds...
That's
12 cases per min
120 cases per 10min
720 cases per hour
4,320 cases per 6hr's
....not counting time spent moving brass in the bins, refilling beer, counting the holes in my peg board on the back of my bench....
The 1050 does it every time you pull the handle and costs $2000
The super swager is $120
Feeding the beast:
The 650 needs a case feeder So does the Hornady LNL AP, Lee LM, RCBS etc etc.
My local shop wants $350 for a LNL case feeder, $280 for the dillon unit, Lee comes with manually filled drop tubes, RCBS?
Dillon 1050 includes the case feed for $2000
Dillon 650 $650 + case feeder =$920 + $120 for swager =$1040
LNL AP $450 + $350 =$800 + swager $920
Lee $300... Wow for that price it's a steal!... Too bad it's a piece of crap.
Trimming:
Don't for even 1 second think you can live without the dillon case trimmer, no matter the press you run you NEED one unless the skin on your fingers is akin to rawhide and you enjoy painfully slow tasks...
Dillon RT 1200 trimmer with .223 die =$400
Misc:
RCBS lube die, Powder cop die, roller handle, strong mount, caliber conversion's, primer tubes, Hornady die lock rings.... You will never be done buying gimmmicky toys.
Best allow another $500... It will get you started anyway.
Components:
With a big hungry press comes a whole new shopping experiance, Expect to buy bullets minamum 1000 at a time, powder should be purchased by the box not by the pound, primers are more affordable in 10,000 lot's, Mil cases are $80 per thousand thru most site sponsors...
Powder 7lb's WC735 from Higgs, $140
Primers $30 per 1000
Cases $80 per 1000
Bullets $110 per 1000
The moral of the story? When you add it all up the press is the cheap part...
For .223 nothing beats the 1050... It's what it was designed for!
Cost recovery on a fine machine like the 1050 is double that of the 650 when you reuse your brass.
.223 rem commercial Ammo is around $350 per thousand rite now
If you can take advantage of bulk purchases you will get your reload cost to around $200 per thousand, with a $150 savings per thousand x4000 rnds per year =$600yr your looking at around 6yrs to actually recoupe your investment on a 1050 loading .223 with the other time saving equipment you will need... If however you shoot lots of pistol ammo or .308 you could shorten up that 6yr period a lot however you must again add in caliber conversions.
The dillon rule
Super 1050 is for people who reload 10,500ish rnd's per year
XL 650 is for people who reload 6,500ish rnd's per year
RL550 is for people who reload 5,500ish rnd's per year
This is all just one guys opinion of course, I really have no clue about reloading .223 I just hangout on the forum and

Clear as mud?
Good!
