does anyone use H380 for medium bore rifles such as the 35 whelen or the 9.3X62 or similar cartridges? Someone worked up a load for a cast boolit of 285grs in the 9.3 using imr4895 and H380, and at someones advice, I will likely get better accuracy with a slower powder than 4895, so I am thinking that the H380 loads will be ok, H380 is slower than r15,4064 and 4320 and win 748. I am looking to get to 2100fps and no more with this load. so if anyone uses H380 and can re-affirm that I picked an alright powder for my goals, or warn me if it isn't a good choice I would appreciate it! thanks a lot-Travis
