Well it's getting hot here in the S W desert and I'm curious about Benchmark where do I look for temp. sensitivity ratings?

Benchmark is an extreme powder, meaning that it is temperature insensitive. I am not aware of a rating other than that.

Hodgdon rates their extreme powders as good between 0 deg to 125 deg. F. with less than 30 fps spread.

Check out IMR 8208 XBR.It is claimed to be the least heat sensatative powder on the planet.Pours well too.Ive had great accuracy and low pressure in the 204s.

"Joe O", what bullet weight are you using with the 8208XBR? I've been wanting to try it in my 204 but don't have any load date.

Load data on the Hodgdon site: http://data.hodgdon.com/main_menu.asp

I use 28.3 gr behind a 26 gr. Barnes Varmint Grenade. Shoots .218" @ 100 yds.

I load 32 and 39gr SBKs + Nosler 32s.28gr works for the 32s and 27.3 for the 39s.Hodgdon site has data posted.
