So Im getting ready to start making up some loads for my 7mm rem mag. I used to (1980's) use IMR 7828 with 160 grn nosler partitions. I usually load to 3150 fps and measure the case heads for pressure. Does the 7828 SSC burn the same as 7828? Can I expect the two powders to have identicle personalities or no? I never used the SSC before. I know i can fall back on H1000, but the 7828 is just awesome or was awesome when it was just 7828. I should explain myself a little better. I see other threads on the forums about this topic, but I guess what I want to know is if the speeds are still attainable being its a different cut now. Has anyone noticed any case head seperation with same speeds? I measure for it, but wa just trying to find out the nitty gritty and what to look for.
