Flash hole problem

I'm in the process of prepping a batch of Winchester .223 brass. After inspection of the first 100 rounds, I had 8 rounds that had elongated looking flash holes. They look perfectly round when you look down the neck, but oblong when you look in the primer pocket.

Are these cases going to cause me accuracy problems? Deburr and use them or junk them? Thanks
 
I would at least use them one time to see how they perform. Shoot about a 5 shot group with brass you know is concentric and if you shoo that 5 shots in a fairly tight group, then slip in the elongated ones and if they stay in that group about the same, then they are good to go for the rest of their little lives. If they don't group the same then toss them.....Just my thoughts.

I deburr all my cases. But, if you decide against deburring, shoot them. You will never see any difference between them and the rest of your brass. When you look down the necks of the brass and see a round hole, that's the hole the primer flame goes through. The elongated hole you see looking into the primer pocket is superficial, and of no consequence. I have Win brass with the same elongated hole and I use it with all the others.
