This might be a stupid question / situation, but I still need an answer.

I have a Tikka T3x TAC A1 in .308. 20" barrel with a Sandman L can on it.

I've tried mounting two different optics on it, a Sig Tango6 4-18x and Nightforce 4-14x SHV F1.

Both of those optics came right off of two other precision builds where I had no problems with them.

The gun shoots and is grouping great, 1 MOA or better accuracy right out of the box with no break in... but its printing about 8"-12" high at 100 yards. .... and i can't adjust either optic's elevation turret to get it any lower. I've bottomed/ maxed them both out. (my zero stop is not the issue)

I was initially zeroing with a zero MOA cantilever mount before I found out the Tikka has a zero moa base by default. I reinstalled my scope into a 20 MOA base cantilever mount and I still have the same problem.

Shooting great groups but printing several inches high and I cant adjust elevation any further. Never had this problem before with a rifle.


Am I missing something or is there something else going on?

Thanks for any ideas.
