What is the optimum barrel length for these calibers? Both my bolt 2506 & .280 rem have 22" barrels and are very accurate using factory ammo! Lots of rifles come in these calibers with 24" or 26" barrels and now I see some single shots coming with 28" barrels. Im just trying to figure out the advantage of a 28" barrel, accuracy, muzzel velosity, sight alignment ( open sights), balance?
