[QUOTE="brianwinzor, post: 109954, member: 1067"] Jimm, I agree with Kirby, and from my experience 3,400 fps with the 90 Mk in a 22/250AI is highly unlikely. The short history of the 90 grain Mk bullet shows that it is also unlikely to hold together at 3,400 fps, as it was designed for use in the .223. I am aware of a few instances where the bullet came apart at velocities below 3,400fps. I am using a 22/250AI with 28 degree shoulder that has a capacity of 49.2 grains, and it achieved 3,176 fps with the Sierra 90 grain Match King. (44.5 grains WMR) Although my 22/250AI has a 1 in 10 twist, out of curiosity I chronographed bullets heavier than the 69 Sierra to see what velocities it was capable of, realising that they would not stabilise. For the record: 69 grain Sierra Mk - 3,430 fps 75 grain Hornady Amax - 3,338 fps 80 grain Sierra MK - 3,267 fps 85 grain Wildcat ULD - 3,176 fps 90 grain Sierra MK - 3,176 fps 100 grain Wildcat UlD - 2,952 fps Hope that the above is of some help.
