Looking to load up some 95gr partitions. 7th edition of the Nosler book, list IMR 7828 41.5 - 45.5 gr as loads for the 95 gr bullets. Do I need to adjust the powder charge if I am using 7828 SSC?
the same load data works with either powder . the ssc powder will be much easier to work with in the 243 case . you might even be able to use more ssc powder since it's not so bulky . this was the problem I had using IMR7828 , I was very compressed trying to get enough in the case . this was before the ssc was available .
I don’t have experience with this combination but if load recipes aren’t available for the SSC, I would personally just start a grain or so below max for the standard cut. Some are more conservative than I am and might start even lower, but my experience is that the “big” 6mm cartridges like to really run with light bullets.
I happen to have a pile of those 100gr NPTs on hand and a pile of 7828SSC to boot. Might have to try a stiff load in the 6x47 Lapua. Right now my 105gr Berger HVLD runs like a tack driver at 3090 on Varget.
