RL19 and 338 Win Mag - 08/07/03
I am thinking of working up a load for my pre-64 Model 70 in .338 Win Mag. My plans are to utilize the 225 grain Nosler Accubond, Norma brass, and initially RL19 powder. I have a concern regarding RL19. This will be my first time working with it and somewhere in my foggy memory I seem to recall someone talking of significant fluctuations in velocity w/r/t ambient temperature. More significant than you would see with IMR4350 for example. Since I live in Alabama (warm) and the intended target will be Montana elk (cold), I wondered if anyone out there has had experience with RL19 in this regard.

P.S. I just read another thread on the .338 Win Mag and RL22 seems to be preferred in most of those cases over RL19. The same question though - can I expect unusual velocity fluctuations with RL22 over temperature variations when compared to other powders?
