I resently picked up brass at the range that I thought was .223 Rem however it ran through the dies a little tighter. It has LC 11 and a circle with a plus in the middle. Is this 5.56 nato brass ?

  It's Lake City 2011. Probably fired from a M-16, or something with a big chamber.

  A slightly larger chamber combined with the potentially slightly thicker brass at the head of the casing could yield the increase in effort you found. You may want to weigh these cases against some of your standard cases. If the NATO, the cross in circle is the NATO mark, cases are heavier than those you have been using it may be wise to reduce your load to compensate for the reduction in case capacity.

  Just finished loading 900 rds of 5.56 on a single stage press. Just use enough lube!

  And I use a small base die, otherwise I have problems with the brass in my bolt action .223 and one of my ARs.
