[QUOTE="Deputy819, post: 1430618, member: 98025"] H4831/H4831SC are the same powders and have identical burn rates, but H4831SC is cut shorter in kernel length to allow for better flow/metering. The shorter kernels in "SC" will allow for slightly more powder volume than H4831. That being said, I would still do load work up if switching from one to the other. IMR4831 is a slightly faster powder in burn rate and load data is NOT the same as H4831/H4831SC. [/QUOTE]
