[QUOTE="James Jones, post: 68609, member: 8843"] I think that alot of guys over look some of the more benifical aspects of the Ackley Improved case , like the steep shoulder and minimum case taper helping to reduce case strech and improve burn ability of the powder used. In cases that are already "over bore capacity" changing to the Ai version will generaly not give to much of a velocity gain , this is the case with the Swift , but the Swift does have ALOT of body taper and slow shoulder angle so it should be a good canidate for the Ackley improvement if you can see past the low velocity gain , hell personaly even if going to the Ackley desgine cost me 100fps in my 22-250Ai I would still do it just for the improved case life [/QUOTE]
