77gr SMK's and 77gr TMK's for the most part. It averages around 1 MOA for ten(10) rounds with quite a few factory loaded combos. Blackhills Mk262 77gr, Hornady 75gr Match, Federal Fusion 62gr, Speer Gold Dot 62 and 64gr, etc.
Zero confirmation a week ago. Less than an inch for ten rounds with a 6x scope and bipod.
Tikkas almost always shoot very well- the 223 8" twist guns are just stupidly wicked precise.
