300 AAC

The MA blackout die is made for .309 bullets, I have some Sierra's and most better quality bullets are .3085 and give enough neck tension. However I have some 147gr surplus plinkers I use for punching paper and getting trigger time. They aren't very consistent, but they're cheap 😉. They're only .13¢ each. The problem is they're all right at .3080 and don't give enough neck tension. My question is for those of you that use bulk bullets, what brands are consistently in the .3085 range? I'm looking to stay under .18¢ if at all possible. Just don't want to spend .20¢ - .40¢ to punch paper. I know Hornady and Speer make some in the .16¢ - .18¢ range, but are they .3085? I'm gonna use up the remaining 147's and want to get some that will work with the MA die. Thanks 🙏

Have you seated a 308 diameter after sizing?
