Need to confirm data pls... I have 3 sources showing max load of RL15 under a 150 sp at ~46 grains HOWEVER, Alliant's website shows max charge of 49 grains. thats an uncomfortable difference. My manuals are less than a year old, and the alliant data is on their current website.
I just loaded up a batch for the new powder from 42-46.5 and will watch for pressure at the upper end, but I hardly think there is another 3 grains worth of space left in the cases... not to mention it could be a VERY hot load at 49grns.
