I switched to BL-C(2) for .308 from the old standby 4895. Load data seemed to indicate lower pressures and higher speeds. I've found that with my reloading, with cast bullets loads are usually a SMIDGE (like maybe 1gr) under listed minimum loads.
With the 4895, it simply won't shoot with such a light load, gums up my brass and action with soot and unburnt powder, etc, etc. The BL-C(2) works like a dream. Comparable speeds, tighter groups, less soot, no unburnt powder, and less pressures on my old milsurp girls

I've found it to work well in 6.5x55 and .303 brit as well. It has become my go-to powder. If you do a little digging, you'll find it listed for loads from everything from .223 to 30-06.
And those who say it's being cheap or "tight" trying to use one powder for everything, isn't that the whole point of reloading? With cast bullets, i can reload .308 or .303 for about 6 bucks a box

Factor in the savings with a 8lb keg, it makes sense to try to use one powder for multiple calibres.
