Since Eric Stecker published his article on varying the OAL by .040 to find the sweet spot I figured I'd give it a try and see what would happen with a 280AI I have been using the 168 VLD's in. Right now I have them set at .015 off the lands. If I truly did find a better setting at say .130 off - anyone got any thoughts on what I might expect for a velocity difference. Right now I'm getting 2825 fps out of a 25" barrel using H4831sc. The reason I ask this is that I use a turret that is set at the 2825 and any drastic velocity change would mean some turret changes.
