Got to Chrono Thursday night, 60° temp and 16" barrel. 2014/2015 Fusion MSR was 2778 fps and 80's Malaysian M193 was 3112 fps.
Trying to replicate the MSR with 62gr Gold Dot, CCI #41, Perfecta/Fiocchi once fired cases (flash holes are not pretty), and Varget.
24.9gr = 2788 fps
25.1gr = 2817 fps

Looks like 24.9grs is about right..

Thanks for the chrono data, I actually prefer Fusion MSR over gold dot because it’s loaded hotter with faster velocities. The gold dot is loaded pathetically weak even for .223.

Good info thanks. The 62gr Bullets are the ones I’ve developed the least data for. I have plenty for 55, 69, and 77 and for 62gr TSX. A while ago I bought a bunch of the 62 GD but have not got around to developing loads for it yet. These results will be good input for my initial ladders.

I too have found the Fusion brand of Ammo to be accurate in the 308 variety. Pretty cheap and pretty accurate.
