BL-C2 or H335 perform well too.
I was shooting 33.5 grians of a milsurp, WC 846 under 150 grain bullets in my barrel. It was delivering 3/8" and 1/2" groups at 50 yards and 2360 fps.
The plain old Remington 150 Coreloct, yeah, the cheap green box stuff was the most accurate laod I ran through my barrel. It never exceeded 1/2" at 50, and was more often a single wallered out hole. I didn't find a handload as good,bt went on to other things and sold the barrel recently. Present owner is quite happy with it.
