Did you try it at or close to the max listed? It seems to work better towards the upper velocity charges.I've tried it in several cartridges including 223 Remington and haven't found it all that impressive except in a 270 Winchester with 130 gr. bullets in which it's excellent.
I had 2lbs of this stuff, sold it because I already have 2lbs of Varget and have 24lbs of CFE223 on the way. I already have sub MOA Varget loads worked up and I ought to be able to find a good load with the CFE223. But seeing that group I'm starting to question my choice to sell it.
Yes, I tried it at up to the maximum charges for my gun.Did you try it at or close to the max listed? It seems to work better towards the upper velocity charges.
