I'm running some .311-sized Missouri Bullets right now, working my way up to the max, 10.0 grains of Unique.
I started with 7.5 gr and then 8.0 gr. Both are noticibly softer than factory stuff, sounding and feeling more like a stiff .22 Magnum than .30-30. The groups were good - sub 2" at 50 yards, but 6" below the POI of factory 150gr remington.
I think this will be a fun plinking load. I have a pound of Unique to play with. When I burn that up, I might pursue something else. If I can find it, I want to try 2400. I've heard good things about Accurate 2230, also.
