I thought when I wrote that one description that it might be interpreted incorrectly. I have experienced two different powder charges showing similar velocities which means you have maxed out the velocity. This is NOT what I was describing. In my testing I shot four rounds with each charge weight noting velocites. This happened twice: when shooting with the same charge weight I had two of the four rounds register the same velocity. When shooting with one more grain of powder I also had two of the four rounds fired with same velocities.
I will agree that RL-17 works with a limited number of cases. I also agree that the 300 WSM is one of them. So is the 284 win, 6mm Rem, and even the 338 RCM. It would appear the midsized cases thrive on this powder.
It is apparent that RL-33 has limited applications as well.
Regarding Alliant listing loads that make RL-17 appear to surpass other powders...that is not the case. RL-17 IS a longer burning curve powder. Just look at what Bob Jensen and German Salazar found with a Oehler 43 equipped for pressure-testing: Alliant Reloder 17
These powder made by Nitro Chemie ARE different.
I envy your being able to shoot more deer than I can with jackrabbits and coyotes.
Have to run....
