[QUOTE="Prieto9000, post: 1187994, member: 24952"] I tried some IMR 4451 which is from the ENDURON family and it sucks, at least on my rifles. On Hodgdon reloading page it shows awesome velocity on the .243 win and indeed you can reach very high velocity but SD was awfully high. My magneto said SD 43 out of a 10 shot string. Also tried in my 6.5 CM and had the same problem SD 39 and Velocity was nowhere near as my RL-17 Load. I´m getting around 2930-2950 fps depending on how warm the day is while 4451 just gave me 2750 RL-17 has showed me a temp sensitivity of 1.05 fps per F from 32F to 86F Just saying that I wasn't Very impressed by that particular ENDURON powder. The way I see it, SD affects my shots even worst than temp sensitivity. Even if I don't even take temp sensitivity into account I can get more consistent shots at long range than with a very stable powder with bad SD [/QUOTE]
