Mine is the SS Target Grey model with the two-stage trigger. I haven't had it that long, been playing around with 50gr V-max and 34.6gr/35.5gr Varget. Also tried 55gr V-max with 33.5gr IMR 4895. All are sub MOA at 100yd, 55gr seem better.
I'm in Canadian prairies, it's really hard to get powder, bullets or primers here last year or so. Gunshops cite border issues or war effort for the shortage.
Hoping to find a good load using components from different mfr that might be more available.
