I have an axisII hb in a 6.5 creedmoor. When I took it to the range to check it out I noticed what seems to me as very bad muzzle rise. I have to look for the target after each shot and at 100 yards I couldn’t keep it on paper. Moved to 50 yards and got it on paper but with a very large group. I had bought a mdt chassis for it at the same time so I put it together and the rifle now weights 12 lbs with same results. Any ideas? Thanks for any help.
