No, I havent really thought about rechambering it to the Ackley Improved. I really do not know much about that round to tell you the truth. I really like the 30-30 for several reasons. 1. Its a classic 2. It has low recoil 3. Ammo is cheap 4. It is easy to reload and many gains can be found doing so 5. I shot my first deer with one nearly 20 years ago lol. Maybe I should have posted this question in the reloading forums, but I was hoping to get some feedback on the gun as well.
