Dozens of Tikkas. Yes, I remove the barrel bumps out of each.
There is is nothing magical that happens between 100 yards and any other range to deviate the bullets off of their prior track Wind, and extreme velocity variations are it.
If you rifle is consistently shooting MOA at 100, than given the same conditions it will be MOA at 200.
You you have a couple of blaring things-
1) Three shots is not a group. Worse, “three shot groups” are more likely to lie to you, then give you credible information. Shoot a couple of 10 round groups at 100 yards with a dead on point of aim, point of impact (POA/POI) zero. Then, go to 300 and shoot a 10 round group without touching the turret. The 100 and 300 yard groups will be within .25 MOA of each other.
2) Leupold. More than any other reason, THIS is why people should use scopes and mounting systems that are absolutely reliable. Because when weirdness happens, you now have to add those two things into the possible cause pile.
3) Shoot from the same rest each time. If you repeat the 10 round groups from above but off of a pack instead of bags, your group will be larger. A single “good” group does not data make.
What I would I would do, in order-
Replace scope with a reliable one.... and/or-
Remove barrel bumps heavily, degrease, Loctite, and torque screws
Use sands bags to shoot 2x ten round groups at 100 yards. If still using the Leupold shoot another 20 rounds but dialing all the way up, and all the way down, shoot one round at zero, then up to 10 MOA and shoot another round. Do this for all twenty rounds. At the end, it is highly likely that the group at zero is 1.5 times the size of the initial groups and probably in a different location. The group at 10 MOA will most likely be 1.5 times the size of initial groups, and will not be 10.5 inches high of zero.
Doing the above will tell you two things- what you and the rifle are capable of group wise, and what your scope is doing on a base level.
I couldn't agree more(except for the stock contact).
Whenever I hear Leupold, I figure it's going to fail, if it hasn't already.
I have great faith in Nikon and Burris.
