[QUOTE="memtb, post: 1895547, member: 75451"] adk hunter, I first qualify this comment with......the following may be an anomaly! Several years ago, there was much conversation about the temperature sensitivity of RL 17....which I use in my rifle. As I mentioned, I do my load development during the summer. I waited until a nice cool, calm ( I was testing groups as well) day....with the daytime high at a minus 3 F. Test temperatures ran from a -4 to a balmy -3 F. The rifle and the ammo, we’re left outside for a couple of hours to equal and stabilize to the ambient temperatures. I fired a 3 shot group, allowing several minutes between rounds, as to not change bore temperatures substantially. My velocity actually showed an 8 FPS “increase” over my summer load development data. Also, exhibited a group slightly better than the summer groups. Go figure!!! memtb [/QUOTE]
