I’ll add to the list with my process.
I have more than a couple 223 AI builds.
I had my smith build me 2 AR15 barrels also. All cut with the same reamer.
I size my bolt gun brass 0.001 off the shoulder datum.
I size my gas gun brass 0.003.
My AR15 barrels are cut 0.002 deeper than the bolt gun.
This way, my sizing die adjustment does not change.
I first planned to shoot everything in Ackley.
In practice, I’ve worked up fire form loads in the AR15s that shoot very, very well.
Prepped LC brass with 24.0gr Varget and 77 SMK loaded to AR mag length.
I introduce new shooters and let kids shoot the ARs. I’m not shy about supplying the ammo.
They eject my fire formed cases that I shoot in my bolt gun.
I’ve shot Ackley formed cases in the AR, but the mag length limits the benefit with the heavies. Formed case loads in the AR with 60gr NBT or 60gr Hornady V-max are impressive on varmints. They seem to feed just fine.
Bolt gun was set up for 80gr AMAX. I’ve found the 75gr AMAX better for added velocity.
When the ELD-M came out, I found a great deal on the 75gr AMAXs, and bought a bunch.
Varget 26.0gr in the formed brass sends them at 2950fps in the bolt gun.
If I live long enough to shoot up all my 75s, I’ll try another bullet.
In terms of brass, my grandchildren won’t run out
