It also shoots 69 grain Sierra SMKs and TMKs very accurately.
Your 1:8.5 twist should handle the 77 grain bullets very nicely. The bullet will make a difference.
If you are looking for accuracy, target bullets will give you the best results, based upon my experience.
They are expensive but they should show you what will shoot best.
My experience tells me that they like to be seated out farther than factory loads will ever be. But since you reload, you have that option.
