[QUOTE="Trnelson, post: 1880246, member: 42308"] Norma hasn’t released much in terms of data in a while now. Even their 217 powder, which is likely the most optimal powder for 264win and heavy bullets, doesn’t have much data out there for reloaders to utilize, and nothing for 264win with 217. I have contacted them via email several times requesting guidance with a couple of the Wildcats I have and advise on calibers that they have not published yet. I have only received answers along the lines of, ‘we haven’t tested that combination’ or very similar. SMH, whatever. If I were you working with those powders and that cartridge I’d look at what they have published that is similar in case volume and bullet weight. For example, when I was starting out with 217 and 6.5/06 I used their published 6.5/284 data with MRP as a starting place. 217 is quite a bit slower than MRP, so I just wanted to get a baseline so as to not wear my rifle on my face. I loaded the minimum charge weight of MRP in 217 and shot it over my magnetospeed. Recorded the data and re-checked how that related and worked up a load development from there. [/QUOTE]
