I loaded 100 .223 rounds the other night. When i was done i did a little QC and to my amazement the bullets where spinning in the neck. Wondering what my retarded A$* did wrong. Maybe i did not re-size correctly. Maybe it the brass i swaged "speer" might be bad. No i pull the bullets and and use Stevie's wonder Caliper. .224 diameter bullets are .221 and .222. I understand they are cheap plinking rounds, but come on man. Could that not be dangerous, such as the bullet setting back on me, over pressure etc. And what else would happen if the bullet can spin around in the neck? Plus they are VERY inconsistent in length, weight and shape. My suggestion would be to look somewhere else for plinking rounds.
