[QUOTE="del2les, post: 1991355, member: 9299"] Just a couple of mentions: * Your barrel length will not effect your chamber pressures and ability to load "heavier" powder changes. * Several are mentioning the longer barrel gives the powder more time to completely burn, which is not completely accurate. Most modern smokeless powders are completely combusted in the first few inches, and depending on several factors, often while in the chamber/throat area. The longer barrel may allow the gas pressure more time to push on the bullet before it leaves the muzzle, and in some smaller case capacities and projectile loads, too long a barrel can actual impede the projectiles' top velocity. I.e. no longer increases velocity or is actually slower than the optimum length. [/QUOTE]
