Use a drill press to trim down all of the neck and shoulder. Debur.
Lube and run through 300 blk die, trim to length. 
I used a small pair of Vice grips with 3 layers of blue tape on the jaws to hold brass. 
Chucked up the cutter head from my RCBBS trimmer. Put tape on the threads to protect them from the drill press chuck. 
I was using once fired RP 223 cases. Cases are not trimmed square, a 22 pilot does not center well once you get past the neck. That's ok because you trimmed long and after forming in sizing die, trim to length. Others are using a cut off saw from Harbor Freight. I already had a drill press. 
If you try to run a 223 case in a 300 blk die, you lose some cases. Much better to trim first. Cases in bottom right were split and I cut them off with a hacksaw, then the totally crumpled case on the bottom.[:// Good luck. 
And yes I was using Imperial and lubing the inside of the necks. About 1 in every 5 cases were splitting. Didn't lose any cases when I pre trimmed. |

My process is pretty much the same as dryflash's, but I use the Harbor Freight saw to trim the 5.56 brass. I use the .330 diameter headspace gauge from my Hornady set in the clamp to steady the brass while I cut. It's not the cleanest cut, but you are going to trim later. Also, I have the Forster dies-Lee wasn't out when I got mine. I didn't have any split neck issues when sizing before cutting, but I've found cutting the brass first to be easier.

I pulled the decapping stem from my FL BLK die and sized down the .223 brass and them rough trim them with a Harbor Freight abrasive chop saw. Follow that with a final trim with the Forster case trimmer.

When I get around d to making my own brass, I will use this since I don't have a mill in my garage......400,000 rpm of precision cutting power in the palm of my hand

Be sure to report how that works, and what does the cutter look like? |

Be sure to report how that works, and what does the cutter look like? Well, it will cut hardened steel like a hot knife thru butter.......brass should take all of 0.1 secs to lop off at the shoulder. I'll have to get a pic of the bur that I will use. |

Get a Dillon trimmer and trim die, run the .223 brass in and out comes .300 Blk brass, some load it straight from the trim die but others run them through a neck die after the trimmer just to open the neck a little and knock off the sharp edges.

I pretty do a similar process.
1. Cut the case down using my $29 Harbor Freight saw 2. Use a Hornady cam lock cutter to trim to overall length (bout to get the Lee case length gauge though to speed it up) 3. Clean up the brass trimming 4. Run it into a Lee die. I'm using once fired LC brass, so swageing them on a dillon before cutting. I do want to invest into using the Dillon Setup. Using a 1200 and a whisper trim die from http://www.ch4d.com/ it takes no time at all to make brass. A user from another forum: http://i193.photobucket.com/albums/z6/no4mk1t/NFA%20Talk/Kali.jpg I plan to set some sort of stop set up for the case so that I'm getting uniform length cuts more precisely each time, this was the first day and I was really excited to get going so the tape mark was my eyeballing mark. No under cuts, but several cases took a lot more trimming then others. http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/252015_2282607309048_1364790810_2698250_4690300_n.jpg Not my image, but I find a good reference when explaining how the trimming goes: http://i281.photobucket.com/albums/kk219/WhisperFan/Firearms/Whisper-brass.jpg |

I notice the tool head has been cut down quite a bit. Not a bolt on system with the Dillon trimmer. But if you have a tool head modified and the proper trim die, the Dillon trimmer is a great system for trimming 223 to 300 blk length. |

It shows you clamping each round. I saw another picture where a guy had cut a .308 cartridge down, clamped it in the saw then just slid each .223 round inside the case to get the exact same length every time without having to measure or re-clamp each round. |
