Where do most of you set the overall length of 223 ammo when you reload.
Another question about length. I have measured my brass and a couple of them measures 1.719 in length. Should I discard these brass?

I am getting the powder charge from the Hodgdon Reloading Data Center. I am using an AR15. Right now I have some H335 powder and wanted more but, the only powder they had was the IMR 4198. After the weather clears up I will be playing around with different powder charges and then the length.
I'm also thinking of trying the CFE223 powder that came out last year. I don't know whether it's hype or fact about the effectiveness of reducing fowling they advertise about. Maybe if/when the availability is better I'll be more apt to go to the range more to experiment.
I've used about 6# of it so far in my .308 and have noticed a definite change in copper fouling in the barrel. The barrel on my rifle never was a problem as a "fouler" to begin with but at cleaning sessions where I used Sweets, I would notice some "blue". Now cleaning consists of a wet patch with Hoppe's to clean out the "soot". The bore is then nice and shiny. I now use Sweet's every couple of months and their is barely enough blue on the patch to notice.
Yes, I notice more "soot" but it comes out with only one or two uses of a bore snake. No "carbon ring" either. Whatever falls in the gap between case and end of chamber get's "whisked" out by the bore snake.
So far no temperature problems in getting the charge to light off. Waiting for some warm summer weather to see how much it's affected by NW temp swings.
2.26" is the technical "max" for .223 Rem/5.56 due to the fact that it has to fit in AR mags. I find that typically, this length is too long, and have had feeding issues. I prefer to seat to 2.240-2.250" (it's tough to get it exact when you're making a lot of ammo) but anything in that range passes QC. When I load frangible, or some of the really blunt bullets, they typically get seated at 2.18-2.20" in order for feeding to work right.
