I reload for quite a few cartridges, and I am looking to start buying powder in bulk vs 1lb bottles. What powder would you go with for .243, .25-06, .270, .280, etc with heavier bullets? I am thinking either H4350 or H4831, but will consider others. I've had good luck with R22, H4350/4831, etc, but 8lb jugs are a good amount cheaper. Thanks!
