Why would humidity matter?: More humid = less dense air
[/ QUOTE ]
Being a br shooter, I am surprised that you have not heard of this before. Humidity changes everything from internal ballistics to external ballistics. When there is a humidity change, a lot of close range br shooters (myself included) will change powder charges to compensate or change powders entirely-going from say 8202 to 322 to change pressures back to their "sweet spot".
Externally, some guns that are on the ragged edge of stabilization in low humidity will not make it to the target or keyhole the target in high humidity. In my experience, humidity plays about as big of a role in this as air temp sometimes. /ubbthreads/images/graemlins/smile.gif

Nevermind -- i'm a ******* -- misread, i had my wires crossed /ubbthreads/images/graemlins/crazy.gif
You higher elevation is probably close to cancelling out the humidity difference.
I still think you have a hot lot, cause i have talked to people in So Cal shooting a similar load to mine with no problems--desert and all.
My 6.5 hasnt seemed to care about humidity so i havent changed much -- just chasing the lands.
And when it gets HOT i just keep the ammo in the shade -- If the thermometer inside my ammobox reads 60-80deg I'm GTG.
