I am currently using H380 for 243 and 30 06 reloading. I am actually happy with the results, though a little more speed would do no harm. I am not at maximum load so could just load up a little.
However after having the powder in stock for some time my local shops seem to have problems getting it for me. It has got me thinking, is there something that is significantly more suited to both, as if there is i could order a reasonable amount and probably improve a little.
