[QUOTE="antelopedundee, post: 1917331, member: 107384"] A place like Hodgdon would load the AI version until it reached a pre-determined safe pressure which if you look at their data is usually something between 62,000 and 63,000 psi. Whatever velocity you get from that compared to the parent case is your improvement. It may or may not be worth the effort to you. If pressure signs like primer appearance and bolt lift allow it, you could try inching up higher. Also your second point has been answered here a dozen times. Cutting the wildcat back to match the volume of the starting case gets you nothing in extra velocity over the parent case. Shape doesn't matter. [/QUOTE]
