[QUOTE="baldhunter, post: 2856631, member: 11853"] I use 71.0-72.0grs of IMR or Accurate 4350,Win case,WLRM primer with 180 and 74.0grs with 165gr bullets out of several 300 Win Mags.That is a book max in several manuals I have.Lately I've been loading 73.5grs of Hunter powder.Hunter is just a tad slower on the burn rate scale and seems to be maybe a little better powder in the 300 Win Mag a than the 4350's.As for temp. issue,The only time I ever noticed a big change in velocity and pressure with IMR-4350 was when I was shooting at around 100 degrees.Could have been my chronograph,but I was seeing about a 100fps increase in velocity.At 70 degrees,you shouldn't have any issues.Heck here in South Texas,that's a typical temperature even in the winter.
