So much of what he professes probably breaks down quickly when using war bows. His speed would not be that impressive if shooting heavy bows and heavy bows is what wouldve been used for war.
As for this specifically who knows...I do know exactly how plains indian bows perform having made my fair share and shooting an arrow 100 yards and hitting a target is nothing more than luck using one of those. Hell it would be mostly luck with a compound bow. They werent made to shoot far. They are actually extremely inefficient but excellent for charging next to a buffalo and shooting it point blank.
Ive heard of the reload speed of plains indians. I think its possible to have high reload speed but you are going to sacrifice a lot of power and accuracy so its definitely not the only thing to look into.
Sorry Lars Anderson is definitely a controversial figure if youve been in the community for any length of time.
This is Capt. Party Pooper signing out.
EDIT: Heres what it looks like pulling a war bow of legit battle weight from back in the day. You aint shooting 3 shots with one of these like Lars does. Neither is he for that matter.
