I have had guys out with bow and rifle that shake noticeably when it comes to lining up on a buffalo. Especially when the range is close. There is alot of pressure on. Not just financial but they also don't want to look bad in front of you and for some its the culmination of a life long dream and the excitement gets to them. No amount of range work can get them ready for it and it can happen to the best. Can mean some interesting extra work though usually ends well.
