A 44 rem mag has 550 lbs energy at a 100 yds. But some say that you need at least 1000 lbs energy to kill a whiteail. But it seems the 44 would have very little trouble doing this at a 100 yds. See what I'm saying. Energy is not what kills.

17 has higher velocity and the 30-06 has more energy. Which would you choose? According to this theory the 17 would kill a deer easier.

(From www.remington.com)

Shushhhhhh your blowing holes in my theory. LOL See what I mean.
so what is it . I really dont think it's energy because a 45 doesnt have any nor a 357 mag nor a 44 mag. That 17 has more energy at 100 yds than the pistols above mentioned. so again I say energy is not what kills

I don't see it as a debate...it isn't Speed vs Weight..
You must have the appropriate combination of velocity, bullet wieght, bullet construction and point of impact. That is what kills.

2 rifles shooting the same wieght and construction of bullet but at DIFFERENT speeds will have varying terminal results.

You can change the variables all you want but in the end you will find that certain COMBINATIONS are more lethal than others.

I dunno, but that why I started this debate.
A big hangun like a 45 and a 40 SW have around 375 lbs enegry at 25 yds but have around 1000 fps in velocity. Pretty lame on energy but they will definatley kill you pretty darn fast.
of course its gonna kill u gimme a 800fps 177. cal pellet gun and i can kill u pretty fast.... Velocity is not what kills the animal ENERGY is the higher velocity rifles like the 243 u loves so much will hit the deer faster with less power but if u use a larger .30cal the bullit is still gonna hit the deer maybve a little slower but the damage is much greater

So a 17 REM that has 906 ft lbs of energy is gonna kill better than a 44 mag that has 740 ft lbs enrgy. Huh ? ya right

Don,t read like you wanted a debate at all. You have all the answers so ok your the man!

they will both kill a deer fast all u need is a good shot to the neck...i shot deer with a 22 that never made a step all u need to be is a good a shot and have the confidence to shoot for the neck

Your two steping now. LOL

You say energy is what kills. What will stop a hog faster the 44 or the 17, shot in the chest. By your theory the 17 should, cause it has more energy. Now by my theory the 17 should also because it has more velocity. But we both know the 44 will do the job faster.
So weve managed to blow a hole in both our theory's.

I think youve said it best so far.
