Your limitation will be the magazine.
Tikka's are usually long-throated and your chamber will accept a longer OAL than the mag.
You will need to test some empty casing/bullet combos and I would load at the max of your magazine.
In re Berger VLD's, I have not used them.
My favorite bullet for that cartridge (most cartridges!) is Barnes TSX...180 or 168.
They're long-for-weight, being all-copper and they are very accurate.
For powder, I use H-414 but have never gotten close to book velocities..usually around 4-5% under published velocity.
