Actually, When I build any AI cartridge, I cut the chamber like PO Ackley intended us to do and realy there is no need to go through the fire forming process when the SAMMI ammo can be fired in that chamber with very good accuracy and hunting with standard ammo and fire forming to the improved case dimensions at the same time is normal.
If you buy new brass, it can be loaded with near maximum charges and used to hunt with. After that, the improved case is ready to load with the new case in mind. If cut properly, the parent cased ammo can be fired in an Ackley chamber with less than 1 MOA accuracy so you can take advantage of this feature and save time and money and not waste components. On good quality barrels break in normally takes 7 to 10 shoot and clean shots and at that point, hunting can finish the brake in, minimizing useful barrel wear.
If you shoot and clean often (After 3 to 5 shots) break in should not take over 30 to 50 rounds to reach the barrels potential. So why not do the brake in while hunting. Plus if you forget to take the AI ammo, you can buy parent cased ammo and not ruin your hunt. (You would be suppressed how many times someone has left their ammo at home.
