Very nice looking rig !
If you are still considering the HSM ammo you should know they are loaded way way below spec length, shot horribly in my gun, flattened primers and had loose pockets on a few. They were loaded well below the 3.228, I think a little under 2.9"
The good news is they use Lapua brass. I have four 6.5x284's now and I think you will love it !
