well my smith *gunco's Jason Spencer* called to tell me my new Pac-Nor barrel is ordered and will have a slight taper to .930 at the muzzle. my question is the barrel is comeing in a 28" length is this good for a 300Win Mag in a 1-10 twist or should i have it shortened to 26" if i stick with a brake added it will put the barrel length at roughly 30" it seems kinda long and will make it difficult to transport in a case *the current case just barely fits it with 24" bbl* but will it be better for accuracy longer (28") or shorter (26")
