223 at 1000yards and beyond
I have been shooting a 223 at 1000 yards and beyond for some time, and my best reuslts have been with a 26 inch, 1/9 twist with 70-75 grain match, VLD and AMAX designs. I acheive 3000 fps in the long tube and a slower powder with BR primers. My throat is longer than normal, so the longer 75 AMAX and Berger VLDs can be seated out. Watch the VLDs, as you will have to play with the seating depth more closely to achieve the best accuracy. The high .43-.46 BC's and 3000fps are comp with a 270 Win and 130 BTs, and I have no trouble holding my own or beating some larger caliber shooters. F-class places the 223 in the target class for 1000 yards.
For fun shooting that improves competition performance, we often have "soda can" shoots or dynamite shoots at distances that reach 800 yards. Then some of us go for the 2 liter red water pop bottles out to 1000 meters. This can be tough with the high winds in Western CO, but it is aload of fun. We have upper torso steel gongs out to 1240yds and 1500yds, and if I do my part, the 75's will hit more than miss. However, they are subsonic at this range and accuracy suffers.
223's at long range are loads of fun, cheaper than larger appetite calibers, easier on the shoulder for extended shoots, and it is just plain exciting to watch that little caliber reach out over the horizon.
Next, play with a target .22LR at 300- 400 yards to improve your shooting skills at 800-1000. Ballistics are similar and it is much cheaper.
