As far as your chrono data, your 777 numbers seem too high to me. You might check them with Hodgdon's web site. I don't see 50% hotter in your numbers, but they are higher than one would expect. Are those numbers averages, and if so, what were the spreads like?

The chrono was giving fault messages about 75% of the time. I started with it 10yds out and then 15yds. The 777 was recorded 2 times within 8fps, and I will agree the results do not meet 50% but much more than what I was looking for.
The day was hot, and we took time between some loads to shoot C&B and conversion revolvers.
I guess I am lost as to why a hot day would lead to moisture problems shooting 777. Or is 777 equal to BP when it come to collecting moisture?
