3087fps? Damn hot load you're running there with a 69gr .223/5.56
24gr Varget with 7.5rem primer and 75/77gr bthp is pretty much the classic match (SR) loading.
About 2700fps maybe 2750.

Never know till you try, I guess; re twist rate. 80gr bthp was usually favored at 600yds in Service Rifle, but had to be single-loaded due to VLC design of bullet. Probably no worries in a bolt rifle. The Tikka T3 mag could be modded to allow mag seating of the 80gr jobs. 1:8 twist very nice!
