Not a big fan of ball in the .30's, either. As an exercise, I worked up a load for the Garand with H335... that much H335 in that big .30-06 case turned it into a flamethrower! At the same time, I tested H335 in my 16" M1a... same fireball. Seems like IMR is a lot more docile. BL-C(2) has been described to me as 'quite blasty,' so I have to admit that 1) I've never used it, and 2) I'm not likely to ever use it. But... your results are what they are!
If you have a sizeable quantity of it... waste not, whatnot... but if you are going through it, it wouldn't hurt to explore a different powder. AA4064 sounds like a good choice.
