I bought a Lee FCD to load .223 for my semi's. I have been measuring my brass and it all falls between 1.7485 and 1.751 with the majority right on the money at 1.750. The necks on some are not perfectly in line with the bases as well. One side of the neck might measure 1.750 and the other 1.748.

Am I going to run into trouble with consistency in crimps? Should I be picking out the best brass and setting the other aside for plinking?

Any insight is appreciated.
 
IF you read the data on these dies you would know that trim length is not critical. Thanks for causing me to post more useless info.:D

If the case mouths are not flush, I can see accuracy problems being an issue. Is it possible you just didn't measure right, because if they actually were offset like that, I'd definitely recommend giving them a trim, square them up.
 
At 1000 Meters I would agree with the above poster, at 100, dont waste your time. :)

Its all about what YOU want the ammo to do, and how much time you are willing to invest to squeaze out every last MOA from your shooting. Personally, I shoot .223 in a mini-14 at 100 yards .. I do NOT worry about a few thou off square when I trim brass.

My father on the other hand who loads .303 brit and shoots out to 300+ meters is very anal .. and he also doesn't mind spending a lot of time for little gain ..

Ultimatly your the one who's going to have to answer those hard questions ;) Good luck with your loads!
