One more issue to throw in here for the non-archers, at least more technical data.
Draw weight does increase arrow speed, with more speed meaning more distance… BUT, it does so SLOWLY. For every 5 lbs of weight you add to a bow you get an increase of about 1ft/s. (about, very aproximate, will depend on arrow weight as well)
Which brings us to arrow weight. My modern bow shoots arrows that are fairly light. The increase when using lighter arrows is much greater. For every 5 grains of weight you save, you pick up 1ft/s. 1 grain = 0.00228 ounces.
I changed from aluminum arrows (better than wood, but now very un-durable technology) to a carbon arrow (tough, strong, light), and picked up 20ft/s by losing 100gr of weight.
You lose “impact punch” when you move to a lighter arrow, but gain distance and flatness of trajectory.
In modern hunting, the 30-40 yd range, we are attempting to hit a “dime” we want to be RIGHT ON, shooting exactly at a point on the deer, but will accept some variance. In competetion archery, they routinely shoot at 80 yds, but at very large targets. As the target moves further, the target gets bigger.
While I’d certainly believe that modern archers, even with “homebows” (home-made traditional equipment) can reach out to 300+ yards, they can’t hit man sized targets reliably. As I said above, that doesn’t matter when you have 1000 of your friends throwing arrows to the same arena, but does not mean they are “accurate” at 300+yds. The mission is different, it’s not the same comparison right from the start.
If I had a large enough safe area, I’d love to try this out. Alas, I’m not sure I can pull this off in the area I live in. Hopefully the posters above will report back their results. Please let us know your “group size”!
