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

Just like the title says.... anyone had a 1-8 Tikka .223 not shoot the 77 gr loads well?

mine didn't shoot well. I found the stock was tight to the barrel. I used a dowl and widen the stock barrel channel

And how did it shoot after?
