163bc,

I agree, my test was not an all inclusive, scientific test that removed all of the variables. It was simply a quick check to give me peace of mind before I chose a powder for my hunt. My goal was to just pass on my limited experience based on what I have seen. I appreciate hearing from someone that has had positive results with RL-22. I may try it again in the future and put it thru a little more substantial tests. RL-22 actually gave me slightly better groups and a higher velocity so if I could convince myself that it was not affected by the temp I would probably switch back to it.

Also, and I realize that these tests could be considered biased because of the source, but he Hodgdon website shows that RL-22 had a velocity loss of 75ft/sec over the same temp swing that H4831SC only lost 10ft/sec.
