Those of you who use a progressive press to reload 223's
do you worry about chamfering the case mouths or just run through all the motions?

I have always noticed lots of copper peeling off if I dont chamfer. cant be good on accuracy or keeping the barrel from copper fouling

thoughts?
 
You are correct, it is not good on accuracy. The case trimmer I use also chamfers. If it did not, I would chamfer by hand. Some of the more expensive progressives will bell the mouth first (yes, even for .223). But I still think it is a necessary step.

I load on a dillon 550. For rifle brass I break it up though.

One run I resize & decap, but nothing else. Then I take the brass & do all my chores, trim, debur/chamfer, clean the primer pockets. Box it up & put it away.

then when I want to load I have a toolhead without the resizing die. I take fuller prepared brass & load it.

I will also tumble and hand prime the uniformed cases and store them in sealed freezer bags. I also stay away from large grain powders and compressed charges when loading progressive for the .223, .204 and similar cartridges. Most of my 223s are loaded single stage but I still use the Dillon.

Same here Stu. I do like the shorter grain stick powders like Benchmark. Lightly compressed charges won't spill during assembly, if your careful. The long grain powders do have more of a tendency to bridge going into a small caliber case mouths.
 
Chamfering, uniforming primer pockets, deburring flash holes and stuff like that only needs to be done once, or in the case of chamfering, only after trimming. Prep your cases properly and your loads will be more consistent. I also load like Stu Farish, where I prep and size cases, then run them through the Dillon, in my case a 650. Something about cleaning lube off cases by hand or tumbling loaded rounds to get it off never seemed attractive to me.

keep in mind that you only need to debur & chamfer after trimming. So if you're decap/resizing & continuing to load, there's no need for it any way. You did it the last time you trimmed it.

For my rifles, I always trim after firing, so it just made sense to break the job up.

I use same procedure, except that my press is an upgraded 450 (no tool head). I genereally prep and load complete batch instead of storing prepped brass. Have found it easier to trim after every firing using Lee trimmer & cordless drill than to check each time for length, then trim.

Have never tried 4895 in .22's but meters fine in the Dillon measure in .30's. Use ball powder in my .22's.
