Sounds like that is reasonable. But as a new guy, I'm measuring stuff first at my reloading bench before I go out to the National Forest. Hence my question.
I've been out shooting my new ML rifles twice.
Thanks to all of the interesting suggestions here, I now have a firmer idea of how much to measure and how to do it. Also, how to store pre-measured powder for "the field".
I would not be likely to be carrying a scale in my pack in the woods.
