I was informed by an archer from Texas, that the arrows for buffalo had to weigh 1,000 grains & the stick bow(recurve) had to have a draw weight of 150 pounds. I do not know the country he was referring to, but I think Tanzania.
A compound bow needed the same weight arrow and 100 pound draw weight.
At that time, has having a set of 175 pound limbs made for his Black Widow recurve bow.
He was a hell of a good shot with the 75 pound limbs on that riser, on the moose hunt. After the morning hunt, up until and just for a short while after lunch, we'd shoot in camp, at a deer or maybe the cougar target. Lotsa fun!
I was on "camp protection" those years. My .458 Alaskan was in hand for that job. Had a minor grizzly problem when there was moose on the rack.
