My guess is it has something to do with the long throat not allowing a normal pressure curve. The throat is so long that it isn't possible to start a bullet anywhere close to the lands because of the magazine length restiction. ...The faster powders do seem to get closer to their repective velocities but still not what I am looking for. This furthers my belief that the low velocity is a product of the long throat. Because the rifle is so accurate I am very hesitent to mess with the barrel at all. Any ideals? Thanks, reflex264
It's not the length of the throat, but the diameter of the throat that's causing your problem. The fact that the faster powders reduce the issue is another clue, as they will cause the bullet to opturate sooner, IE in the throat, and retaining more of the powder gas behind the bullet (where it belongs).
