Thanks for all the great info guys, I have learned a lot. As far as powder goes, I have no interest in using a powder that is not temperature stable for the simple reason of we shoot in temps +20c and hunt in temps as low as -20c.so the less the temps messes with the powder the better. The reason I'm trying to stay with h4350 is I have 5 lbs of it. If things don't work out with the 150's I will try a different bullet
I went to 165 and 180s years ago in my 06 and never looked back. I understand using what you have. When you run out of 150s give a heavier bullet a try with 4350 and I 'll bet you will be glad you did. Also if you do go with compressed loads get a Lee factory crimp die. They are cheap and you will never have to worry about bullet movement. Back your charge down a little and work back up as it can affect pressure a bit.
