Its certainly quite good at getting a fair bit into a case. I'm even using it in the 308 with great results and I'd have thought it too fast for that.
Bob - that's interesting. Do you normally use powders that are 'slower burning' than 4350 in the 308 ?
It's been a long time since I had and loaded for the 308, but I never used powders that S burning. BUT I didn't load heavier than 150s.
