.338 Win Mag
My take (at this point)...they meant to graze him, not kill him. They expected the media to have a field day with the supposed background of the shooter. Perhaps they think Trump would come out and support an "Assault weapon" ban for the good of the country. You got Dems saying "we need to come together". Those slimely evil bastards have motive.
No they very much meant to kill him. Whether the shooter acted alone or is part of a conspiracy the attempt was definitely a failed assassination.
