Jim, I have used I4350 a great deal in the .300, but mostly with lighter bullets:150 or 165..I did have a good load with 180's and 4350 for the second barrel on my old 300...but at the time didn't have a cronograph...I would think 3100+ is a bit high..but that load was accurate in at least one of the barrels on my old gun...If I were starting out today, I would go with Re 22..but that is because I have a bunch of it..I have friends who like Re25...
