[QUOTE="Fiftydriver, post: 65786, member: 10"] Jimm, For the 243 AI with the 107 gr Smk you will need the 1-8" twist. This would probably work fine with the 85 gr pills as well. You would have no problem at all with the Ballistic Tip family of bullets as they will handle any twist rate at these velocities. For a conventional cup jacketed bullet you may see some problem with bullet integrity failures. A properly chambered AI rifle will shoot in the 1/2 moa range with fireforming loads given it is a quality rifle to begin with. If you take a factory 243 and rechamber it you will probably not get this level of consistancy with fireforming loads but in a properly machined match barrel, this is fairly easy to get. Good Shooting!! Kirby Allen(50) [/QUOTE]
