I’m not home so I cant check BUT if you hunt with a Tikka I’d advise against using the Sterk.
It’s an extremely nice handle but it’s too close to the hand and can be lifted every so slightly when you’re full of adrenaline and I guarantee you won’t notice it. Then you go to pull the trigger and it goes “click” and no bang due to a light primer strike.
I thought there was an issue with my gun, I had a light primer strike on a follow up kill shot this year. It was bolt lift. I immediately ordered one of the UM bolt handles and knobs. Much better for hunting.
If this is for ringing steel by all means the Sterk is sweet. Just not for me when I’m trying to kill stuff.
