I was discussing terminal ballistics in a 300 Jarrett or similiar rig with a chap recently . His experience was that the Bergers would frequently strike a target sideways (I assime tumbling) at long range. He really likes the Accubonds. I'm looking for bullets to use in long range hunting that have a high BC to shoot from a 300 Jarrett, a 7STW, and a .264 Win Mag. Being new to the long range sport I'm looking for any advice. Y'all sometimes use letter abbreviations with which I'm not familiar. Is there a table of these so us new guys can know what you are talking about?
