[QUOTE="tdot, post: 2285104, member: 91330"] Just a note, the Bullet Stability Calculators are designed around lead core bullets, which typically have a different center of mass vs a pure lead bullet. So while the Calculators have proven very accurate for lead core, in my experience they don't consistently work for copper bullets. Personally I have found Hammer's twist recommendations to be the bare minimum (I shoot at sea level) and have had instability with several of them. I have seen zero negative consequences from shooting faster twist barrels with either Hammer's (for Hunting) or Bergers (for target). So now I decide on a caliber and barrel manufacturer and simply order the fastest twist they make. It makes the decision process very simple. [/QUOTE]
