But I also haven't shot it across as wide a variety of temperatures as I prefer before coming to any conclusions.

Have done all shooting so far in "normal" to 90-degree conditions so far, but am waiting for fall to test it in temps around zero, as in my experience powders (and primers) don't act the same when only the ammo is chilled and not the entire rifle.

But I can say that so far 7977 seems to be a very good addition to the powders in the H4831/RL-22 to Magnum/H1000/7828 range.


MD,

You hit on my exact concern, how will it perform with large charges in Wyoming/Montana Elk season condition.

You didn't use logic or reason to get into this opinion, I cannot use logic or reason to get you out of it.

You cannot over estimate the unimportance of nearly everything. John Maxwell
