Gents , I have a 116 in .300 win.mag. My understanding is it has 1 in 10 twist . The chamber has a long throat , so loads that will fit in the mag. are well back from the lands.(I dont have the numbers with me now). Has anyone had success with loads well back from the lands or will my most accurate loads likely be too long to fit in the magazine ? Any info. will be appreciated , as I'm trying to come up with an elk load (maybe 200gr, accubond or barnes lrx ) thanks , scott
