Ive noticed in other applications that RE17 doesnt like the hottest load, my 6mmREM likes 41grs with the 105s, 44 being he max,(Speer 100grain) had a 2.5" vertical dispersion @600yds and a total group size of 3.5", tried RE17 in my 39-06 as well, 53.5grs shot very well out to 300yds,(tab over and inch) 54 opened up higher and to the left. Not sure about temp sensitivity, never shot it in temps over 85. German and Bob were shooting in temps about 100, so........they didnt mention anything about temp sensitivity.

NOTE: Ambient air temperature during all our tests was about 100� F. Keep that in mind when looking at the load tables.
