[QUOTE="diggler1833, post: 3858501, member: 48072"] 1) There are multiple charts if one just does a ".308 velocity vs barrel length" search on Google Images. 2) A good rule of thumb with the .308 and medium burn powders is about 25 FPS/inch. So what does that mean? Well, using my personal example of a 165gr Nosler BT at about 2,680 FPS at the muzzle; I keep velocity above 2K FPS out to ~380 yards. * My personal limitations on hunting ranges are that I like to keep impact velocities above 2K FPS...you don't have to worry about bullet failure to adequately open/excellent crushing and tearing etc...(that's a long rabbit hole, so I'll stop there). My barrel is also 26 inches. A 20" that reduces velocity by ~150 FPS (2,530 FPS) would see that 2K FPS threshold occur at about ~ 310 yards...so a loss of 70 yards range to increase portability. It is up to the end user and their circumstances to determine if the trade-off is worth it. Now you can load around that to make up *a little* for the lost velocity...but if running your load to the ragged edge of pressure doesn't give you the accuracy you want, then it is pointless.
