Today i went to the range with my 300 win mag to try some ammo out. I took fusion 165gr,hornady custom 165, barnes vor-tx 165, and federal blue box 180. I could only shoot 100yds at this range and the fusion, and hornady hit very close to eachother and the blue box was about 1" lower. Heres the barnes hitting 3" higher than the other 165's, has anyone else had this happen? This was shocking as i hoped the 165's would all be close. Could it be more, or better powder?
