[QUOTE="WildRose, post: 890219, member: 30902"] PB you only need a given volume space wise to burn a given amount of powder. Once you get near 100% burn additional barrel length is going to be of no benefit whatsoever. As for the 1:11 twist rate 1:10 is generally preferred in .30 cal but at these velocities it might do. The advantage to greater bbl length is that you can use slower powders to get additional velocity without pushing up chamber pressure. Check the recommended twist rates for the bullets you are considering using. The Manufacturers generally list them on their websites and if not you can call them. [/QUOTE]
