Minimum case length for .223?

In trimming some odd lots of 223, I ran into a batch that (once-fired) are 1.73" long. I've been trimming others to 1.75" (Maximum in the books is 1.76").

I think 1.73 is still usable, but it got me wondering if there is a "minimum" case length? As I also try to end up with an OAL of 2.26", will the lesser length of neck affect accuracy at all?

my book says trim to length 1.750. that small amount of difference shouldn't hurt your accuracy. Over length cases can result in more than just a loss of accuracy. It can cause pressure spikes. I would keep them separate and shoot them as a group. If you can't find a difference your good to go. The short cases will grow as you know and soon will be in spec.
