So glad I found this thread. Although we don’t have most of the powders listed due to our crappy laws, some of the ingredients have been banned. I’m shocked they are still allowed in California
I’ve got a 20” 6mm creed with Lothar Walther barrel and with 42.7gr RS62 and 87gr v-Max only getting 2700fps which is far too slow. Confirmed by the speeds listed on here. I’m going to try Viht N140 next. N150 was to slow and didn’t give obturation, I got spot on the rim of the case even with going over book data. I had people run the book data through quick load and the results were interesting. According to that it was way below working pressure and shouldn’t be used. Just in case anyone else has to use viht, it might be useful information.
My rifle built on a sako 85 with a kKC laminate. I had planned to use a McMillan but they stopped inletting for sako just as I had it built.
