I bought several hundred new LC .223 cases, and one of the features of this brass is that the case necks have been annealed.

Does this extend brass life when the brass is annealed before it's even fired the first time?

I ask because I've been trying to determine the length of life for some X-Die prepared .223 brass. I've started to get neck splits after 10 loadings, but I'll try to anneal the remaining brass and see if I get anything more out of them.

But new brass that's annealed? What is the point? Does it extend the number of reloads? Or just look pretty?

All new brass is annealed. The military just doesn't tumble them clean like commercial ammo makers. Well, their suppliers don't.

It extends case life for sure, but it is mainly to soften the brass after getting work hardened in the drawing/forming processes. It needs to be soft to ensure it expands and seals the chamber well.
