Ok so far so good. Give me an example of a cartridge that was Ackley improved.... so what caliber brass did they start with to come up with the AI'd 243 brass, etc... and so the positives greater fps than you would normally have out of that cartridge???
I'll try to help pretty much you start with a 243 then have it reamed to make it ackley improved, you then shoot the standard 243 bullets in the gun and the presure from the powder going off makes the case expand to the new reamed size. Which only makes it longer not bigger. This is called fire forming. Once the case has been fire formed and made to the new 243 AI you can use another set of 243 AI dies and start reloading the brass as a 243 AI. Extra time, extra dies, extra powder, extra bullets because the fire forming is pretty much a waste of a bullet, and not a lot of extra results. There a lot of people that swear by a AI gun but I never thought much of them. Alos as stated above its hard to sell or trade one to a normal hunter.
