I found the .223 too subseptiable to wind drift. The least amount of wind and the bullet drifts off bad. In fact I now don't try and shoot mine at anything over 250 yards. I worked up several loads for mine, and am satisfied with the accuracy, but the bullet just does not reach out like I expected. If I need to shoot something out longer than 250 yards I use my 30-06 Handi. The 30-06 will reach out there to 600 yards real well. I use the Speer 125 TNT, and I can shoot the head off Ptarmigen at 50 yards, then hit a fox at 500 next shot.
