[QUOTE="West Calamus, post: 2221396, member: 110228"] You know the drill. load up 4 of each powder doing ladder test starting 2 gr. under max and move up .7 gr at a time and set up the chronograph and test for accuracy. Only your rifle knows and not someone's else's rifle. Of course I will add my 2 cents. I Like the IMR 4831 and use a lot but definitely has temp stability issues if you load develop in 90 degree and hunt in the fall at 40 degrees there definitely is a big velocity fall off. Never had any luck with imr 4350 in a 300 mag shooting 175 and 200 grain bullets but did with H 4350. Accurate 4350 would be a interesting try. AS far as what you don't have - H1000 always gives me 100 fps faster then book max and will be my powder of choice when it becomes available again. Never used the RL powders but they have plenty of good testimonials in there favor for velocity. [/QUOTE]
