H4831 or IMR4831 for .300 win mag
I am looking for some insight on your experience loading for the .300 wIn mag.
My rifle is a 700P with a 26" 1:10 twist barrel. And I will be using 180 gr sierra gamekings, win mag primers, and remington brass.
Getting ready for a wyoming mule deer hunt.
I am trying to decide between IMR4831 and H4831. Sierra says that IMR gives the best accuracy, but I like the temp stability of the hodgdon. I will be shooting in temps anywhere between 0-90 degrees and elevations from 1,000-10,000.
What have you guys gotten for extreme velocity spreads with those two powders, and what would you recommend?
Thanks in advance for any input.
