Sorry, my mistake. A few years ago, there was a proposal to make the minimum gr arrow used for Moose or Bear in Alaska , something in the 800 grain area. I thought that it had passed. I just checked, and it did not.
I do know that there are many guides in both Alaska and Africa that will not take a customer with such light arrows. Many demand fixed blade broadheads and heavier arrows. They've witnessed hundreds of these huge animals, shot by arrows and they know what works.
Really, just read Dr. Ashby's reports. Many of his hundreds of observed kills are on water buffalo, which are huge - ribs like 2x4's. He records the details about each kill. He's been doing this for many years. After reading his studies, it's easy to see the superiority of heavy arrows with very high FOC.
I know some people who've hunted there with a bow and they weren't using a 70# bow either. One guy went his first time with a bow at justover 80. Hit an elephant just a hair forward at 25 yrds. Hit the shoulder bone. The bull reached back and pulled the shaft out. They searched for a couple days to find it, never did. Still cost him $17,000. I don't think the foc has as much to do with it, as an arrow with weight, a bow to through it and a guy that can pullone.
The same guy has been back several times and hasbeen very sucsessful. His taxadermy billis enormous. Some guyshave it.
