Why is the 500 series not your cup of tea? because of the temp sesitivity?


At the time I was developing loads in our warm weather for use in late season hunts November and December in Wyoming and Montana. When I chronographed those powders in sub freezing temps they lost significant velocity. N160 was better than N560. I had just not gotten around to the Hodgdon Extreme line at that time, where I finally ended up using H4831, which turned out to be the most tolerant of extreme temp variande for me. It was just a matter of choice. In fact, it made very little difference for shots in normal hunting range under 3-400 yards. Made one shot and hit exactly where I was aiming, @ 175 yards after I had just chronographed a load with RL22 that was 200 fps slower in the cold than when I had developed it. Didn't make a bit of difference in the end.
