There are several of the Hogdon 'Extreme' powders that work well for many applications, at least for me. IMR4198, IMR4895, and H4895, although Varget is my go to powder for jacketed bullets in my .223 and .308 (I tend to shoot heavier bullets in both).
When using cast bullets in the .308 I would easily pick H4895 or IMR4895. IMR4198 has also been good but in a narrower velocity range, at least for me.
H4895 can also be downloaded by up to 40% of a maximum load. Great if you have a youngster or a beginner that wants to shoot a rifle that would normally be painful to shoot or make them shy away from shooting. Info here:

I still use Varget, but I've found loads just as accurate using H4895 or Reloader 15.
I think I've heard the words "temp sensitive" more times in the past 3 years than in my previous 40 years of reloading. Varget is an excellent powder. Many loads produce low ES and yes it is fairly temp insensitive. I have plenty of Varget on hand but life goes on just fine without it.
Temp sensitive is only important in a few areas
1. You load to max velocity/pressure. If temps go up too much you will be over max.
2. You need precise velocity session to session. Such as some precision shooting where you need to be able to hit targets at long range without sighters.
3. Different temps means different velocity which means different vibrations in the barrel. Some cases it will be enough to make groups larger. Probably only important if you are after those less than 1/2MOA groups.
If you load to moderate pressures and can take some sighter shots then temperature variation is not an issue. Probably not even for hunting since sub-MOA performance is probably not necessary.
If you can get it, IMR 8208xbr is another great choice for .308 or heavy .223. It also meters EXTREMELY well through powder drops.
For jacketed, I prefer AA 2520, for cast it's Reloader 15, in 308 Winchester.
Winelover
Ditto for trying ReL 15. It is Varget's 1st cousin and my LGS usually has it in stock. If you find a load that works as well, send the joker who wants $50 a lb for Varget a message thanking him for letting you find an alternative powder.
IT AINT what ya shoot--its how ya shoot it. NONE of us are as smart as ALL of us!
I second RL15 as a backup for Varget. Produces some really accurate loads, but, is more sensitive to temperature. My .308 loves it.
All the bench rest shooters on my range swear by it...I never have tried it
