OCW test with PP 2000MR and berger 185 OTM (308)

Rifle is a factory Blaser R8 23.7" match barrel(.308). Performed OCW test @ 200 yards. Any guess on the OCW ?
Thanks, Jimmy

I can tell you its not 3,4,5 or 8. Other than that i'm new to the ocw concept

I'd concentrate on 46.2 grains. The scatter node at 46.8 would point back toward an accuracy node just over 46 grains.

The higher charges are probably generating too much pressure for good accuracy. We've seen the CFE223 do this same sort of thing... while these powders drive hard, they have their best accuracy lower on the scale, it seems.

I'm sure your velocity will be very good at 46.2 grains.

It would be interesting to see what happens at lower charge weights...

45.9, but take it out to 300yds next time.
