I like this. It's all relative depending on draw length and weight. A profoundly heavier and slower arrow won't do any good if it completely misses either though it may penetrate better if it hits the deer. A bow at any given weight only has so much energy to transfer to the arrow, you just need a setup that is at an optimum balance between speed, momentum and minimal sound. Often times a bow being noisy is as much of a problem with deer jumping strings as any kind of arrow weight issue. If you can't quite a bow down enough to keep deer from jumping the string at 25 yards then get a different bow or try a heavier arrow or take shorter range shots with what you have. The only rigs I've had trouble with deer jumping the string, were noisy and would "boing" or make a crack sound when fired. Actually, I'd prefer to hit an enemy with a half a brick that is traveling as fast as a pebble.
Sigh, KE has literally nothing to do with performance. Momentum will always trump KE in that regard. Always.
SpotNstalk u make a good point. Half a brick at pebble speeds would be the perfect combo. I stand corrected my hats off
I do lean towards the heavy side though just my opinion. I shoot a axis st 300. 10.7 is meaty. At 70# it drives deap. All in what ur comfy with at end of the day
Aim a little low. Seriously, that's what I do. I'm not being sarcastic. We get use to shooting a targets that don't move. A real deer is able to move very quickly and it's been my experience that they drop down very quickly to make a jump up and run. Depending upon your yardage to the deer does make a difference. Shooting from too far out gives a deer more time to move and changes the point of arrow impact. So call it Kentucky windage I guess. I'm shooting 30 yards typically. A lighter arrow will give you faster speed but less penetration and is not the way to go in my opinion. Try getting closer to your target. My bow is quite but they all make noise to a degree. Can you do anything to quite your bow down?
