I was wondering if you can have a factory rifle in 243 or 22-250 chambered out to an ackley improved with out much trouble. Is it as simple as just reaming the chamber out a bit or do you have to cut the barrel and completely re chamber? The reason I am asking is that i thought i could fire form some brass so i dint have to when i go with a custom barrel. I would rather fire form on the factory barrel so i dont take life away from a good barrel. How involved is it to chamber a factory rifle to an AI? Is it worth doing for the reasons i mentioned? Lee
