i recently bought a longbow just to try it out and have a bit of fun. it is only a 45 pound draw weight. would this be enough to hunt medium sized game? my arrows weigh 530 grains.
When I started bowhunting, a 45# Bear or Ben Pearson was the gold standard for most hunters, and old Fred was knocking of grizzlies and polar bears with a 65lb bow that didn't have the HP of a good 50lb bow today.
The difference is how far you can shoot, and the shot angles you can take.
Most of my collection tops out at 60-62lbs, and will put an arrow end to end on a whitetail with almost any head or arrow weight that will tune, right out to 40yds, and on a broadside shot, well past that. Much past 20 yds, a 45lb traditional rig requires outstanding distance skills, and a lot of talent as a shot.
