[QUOTE="goose, post: 325867, member: 14402"] Are there any formulas or rules of thumb for how much velocity is gained or lost per inch of barrel length? I'm mainly concerned with 22-30" lengths. Do different cartridges or calibers respond the same assuming hunting weight bullets and "normal" velocities. My other question is does powder burning rate have anything to do with barrel life? I assume long bullets would cause more wear, is that right? [/QUOTE]
