Micron,
If your bullet is 220grains and the rifle is putting out 5000ft/lbs then the calculation on this site (http://www.pyramydair.com/site/articles/formulas/) means that the bullet is going at mach 3/2285mph/3350fps

Is this right?

Close... right around 3150fps [thumbup]

I actually have a chronometer that dumps to my computer when working up handloads... Kinda funny with the 300RUM, cuz it knocks it over every shot from the muzzle blast on the local sensor!
