The last three responses have been great; thanks!
They are starting to go into different territory that the video intended. Remember, I made the video about being overbowed, mainly to explore ideas of what that actually means, and to maybe get people to think more about what that means. As I state, some people have told me that if I can't shoot a bow all day at a tournament I'm overbowed and I think that's wrong. If I can pick a bow up and shoot it confidently a couple dozen times and set it down when I am getting tired (and know it!) that's plenty for hunting situations, provided I'm accurate enough and can handle full draw OK.
The discussion looks to now be moving towards "why you SHOULD want to shoot a heavy bow", or "why shooting a heavy bow can be good", and I'm perfectly happy to go down that rabbit hole and potentially even make a follow up video going in that direction, but I need to get a few more animals under my belt first in order to take myself seriously.
The clean release thing - absolutely! I've had bows I pull around 32# with and the release has been much more critical, in a bad way. Still, those bows were very useful for working on other aspects of my form.
Regarding hunting, it's very difficult to say more is not better (most of the time) as long as we are considering everything else - can you shoot the bow OK, are your arrows tuned, are your broadheads sharp, etc. I think it's very difficult to claim that more poundage ISN'T better when every thing else is considered equal, including the ability of the archer.
We do a lot of culling with rifles down this way and people like to say something to the effect of "you can't get more dead than dead". There are trends that move towards using lighter rifles for a lot of culling, and when shooting from a vehicle under the spotlight it's very easy to place bullets in the head of animals so there isn't much need for a rifle bigger than a .223. Having said that, for a lot of culling/hunting where someone is on their feet, the biggest rifle you can shoot comfortably is more desirable as it obviously leaves much less room for error, BUT, when shooting like this down here we aren't using anywhere near as much of the meat as you'd imagine. My reason for bringing this up is that you can have a similar idea with archery but there are still some differences.
I shoot a .300WM in many hunting situations and if I'm after a really big trophy I often take that rifle as I know it has more than enough power. If I'm after meat, I usually take something smaller because a smaller rifle will usually damage far less meat (as long as comparisons between shot placement are realistic). With a heavy bow though, unless we're talking about busting bones, the wound and wound channel are going to be much more similar to that of a lighter bow. We could also argue that the chance of a pass through with a higher bow is great. That doesn't mean that you can't get pass throughs with a lighter bow obviously, but it's a reasonable assumption to make.
Anyway, I apologise for banging on about rifles on the forum but I'm always fascinated by this type of discussion because there is the crowd who love to use lighter gear and still get it done, and then there is the crowd who go as big as they can because it leaves more room for error. If we have a talk about advantages of heavier bows or I make a video about the same topic, that's the sort of approach I may take.
Cheers.
