[QUOTE="brianwinzor, post: 36759, member: 1067"] Fifty Driver, I think you are being ultra conservative (admirable trait) once again, on your predicted velocities for the 22/6mm AI of 3600 - 3700 with the 80 grain bullet out of a 30 inch barrel. My "unimproved Clark" with 30 degree shoulder achieved 3,735 fps (56.5 grains H1000) at maximum pressure with the 80 grain Sierra in a 25.25 inch barrel. The case when stuffed with as much H870 as I could fit in (61.5 grains), produced 3,663 fps at mild to normal pressure. Several other users of the 22/6mm AI with 40 degree shoulder who I have swapped notes with, achieved velocities of around 3,750 fps with 26 - 27 inch barrels. So I predict you will be pleasantly surprised at what your 30 inch barrel might produce. I am in the planning stage of my next .224 Clark, and yesterday emailed Richard Graves to see whether the new .224 dies he was waiting on, could make bullets of 85 grains or heavier. I will be interested to hear how your 22/6mm AI project progresses. Regards, Brian. [/QUOTE]
