I had some RL 15 that was less than a year old, kept in a dry place. I pulled it out and tried it in a 7.62 Russian round I was playing with. The first and only two I tried to fire failed. the Primer detonated and I could smell an unfamiliar smell but no ignition of the powder. The primer was enough to bush the bullet into the lands and when I ejected the shell the powder was real clumpy and and had some of it had a light brown color. I pulled an unfired round apart and it looked like freshh powder, not like the other two. The air temperature was about 20 degrees and the round had been outside for approx. one hour before shooting. Was it just too cold for RL 15(I haven't heard of this but just checking) or can some one give me some heads up. I have used this same Rl 15 before in 223 remington rounds before with no problem.
