There are exceptions to that statement but that has to do with barrel harmonics. Maybe that is because ALL the scores are laughable from the standing position.Īs pointed out, velocity has very little to do with accuracy. Some who have never shot in the bench matches outdoors at 25 and 50 yards. Seems a lot of shooters are trying that match this month. How does that sound for FUN? Just a little bit tougher than the NRA A-17 target, but shooting 25 shoots rather than just 10 turns it into an endurance contest. Did you know that Paul Johnson (knitepoet) has a 50 Foot FUN match going this month? I know you Dakota guys shoot indoors in the Winter. We miss ya over in the On-Line Matches forum. if there is a tight spot back a ways in the barrel and then it gets looser at the muzzle, you will probably gain some accuracy by cutting the barrel back to that tight spot, as long the tight spot is not back shorter than at 16 inches. 22 caliber bullet up that barrel and if it gets tight at the muzzle, leave it alone. The barrel should be tighter at the muzzle for best accuracy. If you are serious about cutting that barrel back, You might consider what Bill Calfee has been saying in the Precision Shooting magazine these past several months. 22 rimfire barrel length is: "The Quiet Rifle and More Thoughts On An Accurate 10/22," by Mark White, Precision Shooting Magazine (Special 3, Vol. It deals with specifically VELOCITY, however, not ACCURACY:Īnother helpful article to track down which covers variations in. I am wondering, however, what great a variety of rimfire ammo they used in their testing of a 14-inch barrel the muzzle velocity spreads for each, the range distance of the target, etc. Still, there are others who say that a barrel length as short as 14 inches provides "optimal" length and accuracy in the. Stinger) where muzzle velocities are 1500+ fps. 22 LR rimfire-the "optimal" barrel lengths are:Ģ0 inches - for standard or subsonic rimfire ammo where muzzle velocities are around 1100 fps or less.ġ8 inches - for high-velicity rimfire ammo where muzzle velocities are around the 1300 fps mark.ġ6 inches - for "extreme" high velocity rimfire ammo (i.e. I guess my main point is it doesn't matter what length you get, just pick one that you think feels good or looks good or whatever, just get one you like.įor what it's worth, I've read where-for the. If you have a shorter barrel the high velocity bullet will be supersonic when it exits the muzzle and will often transition to subsonic before hitting the target. 22lr bullets down to subsonic velocities before it exits the muzzle, so the transition was made in a stable place (inside the barrel, not in air). You want the bullet to either be subsonic all the way to the target, or be supersonic all the way to the target. accuracy can suffer when the bullet transitions from supersonic to subsonic speeds in flight. Longer barrels are generally more stable to shoot, the weight farther forwads has a dampening affect on the shaking from your muscles
