I've not seen bullet length given, only weight when buying slugs. The weight is what determines optimum weight for twist, not length. All bullets of a certain caliber won't vary much in length as they have to fit a finite-sized chamber. The overall bullet length (slug+brass) should be .001-.002 shy of the rifling when the round is chambered. Or so I'm told. To find the optimum ammo length for your gun, load an empty brass with a new bullet, leaving it about 1/8-1/4" long. CAREFULLY chamber the round, then open the bolt and GENTLY remove the round. Measure it's length, subtract .002 and that's how long to make your ammo FOR THAT GUN. Play with bullet weight and powder loads for optimum performance.
