[QUOTE="milo-2, post: 2309046, member: 33622"] The thread has taken a turn, you have gotten solid advice on backing off your powder charge by a couple knowledgeable guys here. I don't know if any of us can pinpoint the pct of charge to reduce for the load to be both safe and accurate, needs to be fired. If the rifle did speed up, and this was the source of the problem, it may be as easy as backing back down to your original velocity to retain the accuracy you had originally. I have no history with copper solids, so no comparisons. If the velocities you are getting are 1-200 fps faster than almost anyone else is getting, one should revisit what is going on. You made a statement you feel the barrel is fast, well, the only Free speed in firing projectiles down a barrel comes from increased barrel lengths up to a point if using the same components. All the rest of the gains come from increased pressure. You could opt for a slower powder and increase your charge, maybe even increase your velocity with a drop in overall pressure. Good luck with this, and hope your hunt is successful. If you do not have a handle on this, grab a different rifle and tackle this upon your return. [/QUOTE]
