So far lots of powders thrown out but no one is saying they've used them with this weight bullet with good results. One more criteria, if I may. I need this to work well at all temps. Thanks.
Which powder for 77gr SMKs?

You just worked that list down to Varget. That said, you won't see a HUGE variance with many powders based on temps. If you are a match shooter, that could come in to play, but it that does not seem to be the purpose here.

When you're getting close to the edge, finding powders that work great in the spring/fall/winter go over the edge during the summer. I use a load of RL10x in my 6.8 SPC rifle that's great when temps are 75 and below but start flattening primers and showing ejector marks when it gets hotter. Most of these rounds will be shot during 3-gun or 2-gun matches, hence the 600 yard requirement. It gets hot enough late spring through early fall that I'm concerned about temperature sensitivity.

Excellent. Now to find them
I need an 8 lb bottle of at least one so I'm using the same lot. Whichever I find first will be "it."

I run 24.0-24.5 of Varget seated to 2.260 and have found it shoots well in all of my AR's.

I got very good results with AA#2520.
I can second this...
This is the "camp perry" powder lol. This shoots well also.
