Has anyone had a 1-8 Tikka .223 that didn't shoot well with 77gr?

Did you physically check the twist of your barrel?

These shoot well in mine.
And kill whitetail just like the TMK.
Pretty affordable and easy to find.
ADI 55’s for practice.

ADI 55 and 69 have shot well in every rifles I've tried them in.

Do people even read an entire thread before making a comment nowadays?

The rifle hasn't been bought yet. I'm not asking about handloads, or anything like that. Factory heavy 77 grain ammo and a Tikka 223 1-8. All I want to know is people's experience with it. Does your rifle shoot it or not? If you don't have a Tikka 223 that's 1-8, no need to comment. If you only hand load, no need to comment. Thanks

My stainless tikka .223 1-8 shoots the 77tmk from bonefrog into basically one ragged hole. Haven't even tried other ammo yet its that good. Am close to sea level as well.

I did hog out the barrel channel quite a bit and torque and loctite the action screws first thing.

Not sure how mine shot out of the box, first thing I did was take it all apart and hog out the barrel channel…but it shoots 77’s better than the 55 and 62 grain stuff I’ve tried.

To clarify, my gun is an 8 twist Tikka .223 and the only 77gr ammo I’ve shot is factory AAC OTM and Bone Frog TMK.
