only makes sense. wish I had a few more cases of 7.62x39 from 5 years ago.I dont have a 5.45 gun or kit and I may skip that round. to many irons in the fire. just reloading for the 223 is a challange. 900 rounds the other day of neck turned brass is a chore but the results are worth it.I am going to buy some more 5.45 just because the AR 5.45 uppers could cause ammo to go up in price in the next few months. 5.45 is as cheap as you can get right now.
