I am assuming that your question refers to match/target use, rather than as a hunting bullet. The Hornady FMJ's have an excellent reputation in service rifle circles for accuracy. Of course, bolt action rifles are generally held to a higher accuracy standard.
I ran some numbers through the ballistic calculator on the following website:
JBM - Calculations - Trajectory (Simplified)
At 600 yards, the 150 FMJ @ 2900 shoots slightly flatter and has slightly more wind drift than the 175g SMK @ 2700. The 155g Palma SMK @ 2900 beats them both handily out to 1000 yards.
One thing to consider is which bullet your rifle shoots the most accurately. I would recommend that you try all three bullets to see what your rifle likes. Pick the most accurate of the three and go from there.
A number of years ago, I bought a Remington 700 VS in .308. I tried Black Hills Match ammo in 168g and 175g loads and Federal GMM in 168g and 175g. My rifle showed a distinct preference for 175g bullets, with the Black Hills load shooting the best.
The only way to really know what will perform best in your rifle is to shoot it and compare results.
