I am looking at getting the barrel on my 22-250 set back and have been wondering about getting changed to an Ackley improved while I am at it. Is there that much of an improvement to make it worth while. I have dies now for my 22-250 and see that it will cost a bit to get new A.I. dies if I change. There is also the trouble of having to fire form the brass. Is it worth it to get a 22-250 A.I. or is more of just a change than an improvement. I have been told that some cases are helped more than others when you go A.I. I normally don't get real technical when I shoot as I have always thought the best gun for the job was the one you had with you at the time. I also feel we can split hairs as to what is the best gun and bullet but there is no substitute for just getting out in the field and shooting,,, a lot. So if getting my gun changed to an A.I. is only going to give me marginal improvements I would tend to put the money into more lead and powder and just get better myself. Please what are your thoughts on this,,,, oh and don't over think it.
