I recently been gifted with a 25-06 rifle and quite a few rounds of ammo from my uncle. Some of the ammunition that he gave me is hand-loaded. I am in the process of researching all of the loads that he gave me to give me a head start when I eventually start loading myself. The mystery load has a paper which reads 117 59(either this means grains of powder or number of cartridges) and RL25. I cannot find any information online about this powder other that it exists. Can anyone give any insight on this load? Thank You.
