14 inch twist in the 22-250 will typically stabilize all of the cup and core bullets up to and including the 60 gr Hornady sp and the 63 gr Sierra semi-pointed.

The exception is the 60 gr ballistic tip. I could not push it fast enough to gain the RPM needed for stability in my Savage 12.

People who choose to brew up their own storms bitch loudest about the rain.
