Kinetic energy

[pupper]

What animal are you hunting in BC that has a thick enough hide that ANY modern bow cannot penetrate!?

your right, pretty much any modern compound set at 50#+ shooting the right arrow and a razor sharp broadhead will get the job done. Then shot placement is definetely trump!

I mean if you're gonna hunt something enormous like a griz or a buffalo, step up to the plate and pull the extra poundage but mean common, for anything moose-sized and smaller......what are we really comparing here?

what is the point of measuring anything or talking about anything?

interest sake? mans competetive nature? discussion?

come on tinney what is your point here? should we not even mention what poundage we shoot or fps? whats the point of that?

anyways lets get back on topic of kenitic energy!!!!!

B.C. hunting regs say " minimum 40# at your draw lenght to hunt "
Tere is also a minimum bow weight and arrow weight to hunt with if your lucky enough to get a buffalo draw, can't remember, it's in the LEH paper.
I had a chance to shoot and chrono the new Alpine Silverado { IBO 325 fps }
I shot a 452 gr arrow at 68 lbs, 29 draw, 280 fps, that just over 129 KE boys.

Also the magic number is " 450,240" not 450.250.

Thing is shot placement and a sharp broadhead.They been doing bowhunting for hundreds of years with less efficeint bows than we have now a days, but a little KE never hurts if theres an oppps, s - - t happens, animals move, buck fever and so on.

Not to argue Bill but when I do the math it comes out 78.7 KE. Am I doing it wrong? I went to that site posted earlier.

Let me know if that site is wrong so I can re-do my calculations.

There is a min bow weight and arrow weight if your lucky enough to draw a buffalo tag. Don't know right now what it is but its in the LEH paper.

Shot a 452 gr arrow, 68 lbs, 29 draw, an impresive 129 + KE

Thing is shot placement and a sharp broadhead, for hundreds of years they've been bowhunting with less efficant bows than ours now a days and a lot less K E. a little K E goes a long ways for those ooppps shots, s - - t happens, animals move, buck fever.

Well i don't know about that site calculation , but by the way I've been told for years now is :
arrow 452 x 452 xspeed 280 div by 450,240 = 127 + K E

[jessbennett]

according to calculations, that would be just around 79 ft/lbs energy not 129.... am i wrong here??? could be. it has been known to happen from time to time..

[bochunk2000]

Ok I was taught that its the weight x the speed x the speed
450240

I might be squaring the wrong one

what do ya know, my lighter faster arrow has more kinetic energy...........
