This weekend I was doing some metal silhouette shooting at long range. Steel chickens at 200 meters with my ar, knock em down all day long. But then I would take shots at steel boars at 300 meters, and my elevation seemed to be completely inconsistent. Only one hit in every ten shots. The conditions I had where steady 10 mph tail winds gusting to 15. The 300 meter berm was positioned to where I had to shoot diagonally across three other berms. My question is has anyone had experience with varying up and down drafts eaffecting the elevation of a bullet to the extent of feet, not inches. Keep in mind that my loads are 69gr. .223 Rem moving over three thousand fps and my distance is only 300 meters. To say the least, it was something of a frustating day at the range yesterday.
