Is anyone using a 550B to load 223/5.56 and if so, how is it working out for you? I'm thinking about buying a caliber conv kit for 223, but would like to see if it is going to really be of benefit in speeding up the process. Any comments?

Gosh, I'm surprised that I haven't gotten a single reply concerning this post. I guess no one uses the 550B for 223.

Ylee,
While not a 550, I did pick up a 450 a year ago to use for small primers. My intent was to set it up for 223's and Service Rifle shooting and leave it.

Other than getting it mounted on my bench (looks good now with a RCBS 4x4, a 550B and 450 Dillon) I haven't gone any further due to time constraints and not getting enough weekends off last year to shoot one Hi Power match. (Yes I know, gotta get my priorities in order).

No other excuses.

FWIW

I load 7 different calibers with my 550B. I don't load .223 though, but I really can't see how it would be different from the others to process. ??

All I currently load on my 550B is straight wall pistol cases. I asked the question concerning the 223 is because it is a relatively small based case with a small mouth. And of course being a bottle neck case is going to require lubing the cases and trimming to length possibly.

Without exaggeration I would say that I have loaded over 100,000 rounds of 223 Rem on the three Dillon 550B's I have owned since 1986. I load all our Prairie Dog hunting ammo on one. It's not hard to produce 400+ rounds an hour once you get the hang of it. I just about don't use a single stage press for 223 anymore.

I have shot .223 ammo loaded off of a 550B and I was quite impressed with the consistency. It went through plenty of once-fired military brass without a hitch.
