22-250 vs 223AI
Fire forming the Ackley chambered rifles is not as big an issue or drama that some people make it out to be. My three Ackley chambered rifles rifles are a Brno in 223AI, a M700 in 22-250AI and a Sako A3 in 25-06AI. All of these rifles have been rebarrelled with match grade varmint profile barrels None of these rifles have ever suffered problems with feeding issues. The important thing when setting up these rifles is to get a good smith who knows what he is doing to do the work. While extreme highest velocity does not always give the best accuracy what I have found is that I have been able to step up bullet weight a few sizes for the same velocity with the Ackley chambers, for instance in the 25-06AI I now shoot 100grainers at the same velocity that I used to shoot 75 grainers at with the standard chamber and still get around half inch groups at 100yards. The performance of the 25-06AI is exactly the same as the .257 Weatherby Magnum but burning significantly less powder to achieve it.
Another important thing is to buy good Quality brass, As Norma brass is hard to come by here I normally start off with Norma factory ammo and just fireform it and even with standard 25-06 ammo the accuracy is still around 1inch groups for five shots at 100yards.
