Does anyone have any specs on effective distance and accurancy in relation to barrel length? I've been told that with a 20" barrel you can expect to keep tight groups out to around 800m. And with a standard 16" barrel you can keep groups at around 400m. Does this sound right? What about with a 14.5" barrel? Does anyone have any experience or ideas? |

Barrel length is not relative to accuracy. What matters is; bolt relationship to extension, chamber, throat, land and groove cut quality, bore smoothness, barrel straightness, metallurgical reaction to heat, projectile match to barrel, consistency in velocity, and crown. Consistency is the key to maintaining a common impact point. Anything that changes in your weapon as you fire (including you), will effect the impact point of your projectile. But....barrel length will not make a difference. One note -higher velocities, if consistent, will allow for less wind and drop effects. ETA; Higher velocities will extend the rounds fragmentation threshold. Some say 2700 fps is the limit, but the projectile construction will determine that. |
