good day gurus. i would like to ask for the advantages / disadvantages of different types of barrels available for ruger mark II or III. i have marked their models and barrels as displayed on their site. the target and standard models arent described what barrel they have but i think some shooters refer to them as tapered barrels? HUNTER - flutted bull barrel BULL - bull barrel COMPETITION - slab bull TARGET model STANDARD model there are also several barrel lengths available from 4" to 6 7/8". how big is the difference when it comes to accuracy given both are of the same barrel kind but different barrel lengths? thanks for looking.
