Good substitute for AR Comp?

I'm not going bother. It's only getting hotter. It can sit in the shelf until the Fall.

Well, fair enough, and not calling you out, per se but, for those who don’t have the luxury of other powder choices. Backing off the charge weight when it’s hotter and adding a little when it’s colder, can be an effective alternative. At least in some cases. YMMV.
