I'll bet they indeed did worry about this stuff. They just didn't have modern equipment to measure it. I'll bet shaft material was the same, diameter was consistant, broadhead size was a close to the same as they could get. I'll bet one shaft didn't have 12" fletching on it, while the next had 2". I'll bet they had a very good understanding about what was important for good arrow flight. They undoubtably didn't call it F.O.C., but you can be sure that the front of the arrow was heavier than the rear, and that they knew a particular size broadhead worked best.

I'm sure they did, however I've heard that they averaged 3-5 yards on their shots. They worried more about getting close than anything else. I also wonder how many they missed. One thing for certain, the mythology presented on television is not accurate. They weren't accurately shooting animals from 100 yards.

They also weren't limited by the ethics of today's hunters. Wounding animals was part of hunting. Chasing them off cliffs, into pits, traps, snares, burning them out, whatever it took. I'll bet that many a buffalo was shot at very close range, with many arrows before the animal went down, and I'll bet that many wounded animals walked away.

We worry about more things today, because society demands it. We pay attention to F.O.C., spine, consistancy, etc, because we can. Heck, there are guys out there worrying about what brand of bow they shoot, when it means far less than these arrow parameters.
