RPM is what stabilizes, and the LENGTH is what needs stabilizing, not the weight.
RPM is a function of both twist and velocity. No two barrels are created equal, but here is a calculator to get you started:

Look up your specific bullet from the tab on the left, then come back and fill in for your specifics.
Thanks for the calculator and the mini lesson on weight vs. length. Like is said below- being diameter is .224, to add weight you gotta add length, unless you are talking metallurgical components. I'm interested in this stuff- and am going to do some research on Barnes.

WHAT IS "SMK" please?
