I always thought velocity was scalar and momentum was a vector(?).
To further mess with your mind, not only does the arrow have horizontal and vertical components to it's flight, but it's also spinning, which adds arotational vector. It's also oscillating for a good part of it's initial flight.
Arthur P, Im not sure what you hunt. Really I dont care how heavy of an arrow you shoot, thats your choice and that is prefectly fine, but Ive killed several puny deer that field dress over 250lbs with a 365 grain arrow.I dontsee an additional 35 grains making a whole lot of difference.
Passthru,every percentage point that we can shave off the wound loss ratio is one less piece of ammo for the animal rights folks. Don't you agree?
Now, to paraphrase your comment, I could give a rip what you use to hunt with since you seem to be experienced and knowledgeable. But, if you'd have bothered to read my entire post you would have noticed that I'm not talking about people that know what they're doing. I'm talking about the hordes of people who know diddly squat about bows and arrows, who never have walked into a pro shop or even know such things exist, don't know how to tune a bow or even how to properly select arrows and broadheads for that $50 POS compound they bought at the flea market. They're taking that junk out huntingand most of them are not doing the bowhunting community any favors. Extra arrow weight could very well make a difference for THEM.
In fact, if they shoot super light arrows froma 20-30 year-old bow with steel cables and teardrop connectors, rated for arrows at 6grains per pound minimum WHEN IT WAS NEW,they are at great risk for a trip to the emergency room.
Would it hurt you, personally, to accept a 400 grain minimum if it'd help keep one of those ignorant people from getting sliced and diced by a busted cable? If it'd keep just one of them from getting their teeth knocked out by a broken riser?If it'd help keep even one deer from being wounded and lost?Prevent one more storyfrom makingthe local evening news where some animal rights wacko wound up with a wounded deer on his front porch? If it'd prevent just one more black eye for bowhunting?
Frankly, I'm really compromising my beliefs a great dealby not calling for 450 or 500 grains. It's only in deferrence to the light arrow addicts that I am willing to acceptas low as 400 grains.
Put your own prejudices aside, look at the big pictureand think this thing through. See if I'm not talking at least SOME sense.
