To someone that is a good shooter 400 yards is a chipshot.
Agreed. Unless the wind is miscalculated, which is easy to do on a cross-valley or cross-canyon shot.
I hit the elk and it started out leaving by far the largest blood trail I have ever seen. The dark color of the blood indicated a liver hit and chest-high blood evidence on the brush along it's path indicated a pass-through. Stuff happens.
Hope you never have a similar event.
Wind drifts calculations get easier when you know how to chose the correct bullets, which you dont. An elk is a huge target..your a crappy shooter using crappy equipment.
