Dan is right about the overstabilization of the lighter bullets. Over stablizing can happen to "normal weight" bullets as well. It happened to me just about 3 weeks ago. I have an 8 twist 22-250 shooting the 68's and it absolutely burns a hole a 100 and it went to **&^* in a handbasket. I somehow had gotten WAY OFF. And I keep very good notes, so I thought.Anway I reduced my load, adjusted the seating depth,and then tuned it at 200 and 325 yards.
Point being, 100 yards hummer loads don't always shoot at longer range. If shooting longer range TUNE the gun at longer range. Sam
