Any data for RL12?

[Neilm]

I was given a pound of Rl 12 and can't find any data. It was made by Hercules apparently equivalent to 4895. Developed as a powdery for 308 match rounds.
After a fire they moved the plant and it was not produced again. It seems like it might be a good choice for a 250 Savage in a model 99 but I can not find any data.
If anyone has any data I would appreciate it, Otherwise it become fire starter.

I have a bit of Reloder 12 left, and it is superb in the 222 Remington.
IIRC, I am using 23.5 grains behind the 50 grain V-Max. Shoots ¼ moa
if I do my part. It is close to IMR 4895 or Vihtavuori N133. Dave.

Thanks IvoB and Eagleye. That chart is just what I need

Just going by memory here, but iirc in the back of the Speer Manuel 11 was some various loads. The powder was new at the time of printing.
