My picks would be, H4350 first. It is one my favorite 30-06 powders, and is most temp insensitive of the three. Second, I’d choose IMR4895, it is an extremely versatile powder, works well in many calibers, is a tad fast burning for my liking in 30-06, but still a very viable powder for it. Third I would go with AA2520. It’s a great powder, but one I typically avoid if hunting in temperature extremes. Some say to use magnum primers with ball powders to ensure consistent ignition in cold weather. I have never tested that on my own, just what I’ve read through the years.

Slower powders will typically yield better velocities in the 30-06 (to a certain point, some are just too slow for it), even in a shorter barrel. Unburnt powder may be of a concern if using a suppressor, so that may bump 4895 into first place over 4350 if that is an issue. Velocity or full powder burn, now I’m even second guessing myself.

This is just one mans opinion, maybe somebody else will chime in with their experiences, and reasonings.
