[J.W.308]

changed arrows because of not having enough funds to get the carbon express maxima hunters . I went to the terminator 4560's . I know these arrows are heavier. So the question is will they carry more energy

 

[TNDeerGuy]

Yes, they will. They will not fly as fast, but they will carry more energy for a longer period of time. Look at it this way...you throw a ping-pong ball and a baseball at the same speed, which one will travel further and which one will hurt you more when it hits your ribs?

good point tndeerguy i can tell a big difference in my heavier arrows by the sound they make when hitting my 3D target
they hit alot harder than my lighter ones, shake the target more too so lighter isnt always better j.w.308

 

[Mr.Bro]

Well someone teach this old man something.Wouldnt the amount of speed lost be factored in?I dont believe just because you went to a heavier arrow you would gain energy.If both arrows weigh the same then yes you will have more energy with the heavier arrow.But if you lose to much speed you will lose energy.Surely someone on here can figure out at which point you start to lose energy

the heavier arrow will lose a smaller % of speed than the lighter arrow as the arrows travel further!! The futher they travel the bigger the gap grows in that percentage!!! So in theory, at very close range there will not be much difference and at 40 yds the speeds will be much closer between the two arrows with the heavier arrow retaining more energy.

Non-powered objects lose energy the moment they leave their propulsion source, in our case--bow and arrows. Very good explanation titansfan. In physics, the heavier an object is, the longer it takes for that object to lose momentum/speed. That is why, as titansfan pointed out, at 40 yards (an example) the two arrow speeds are further apart than they were out of the bows--the lighter arrow will have lost momemtum/speed at a faster rate than the heavier arrow, therefore the initial speed advantage it had is now gone and the kinetic energy winner goes to the heavier arrow because both arrows are the same speed, but not weight. Actually, the kinetic energy winner was always the heavier arrow in our example.

You may need to zoom your screen in to see these screenshots. In 25 yards the difference between the two arrows are as follows� A reduction of 4.3 lbs/ke and 8.1 fps for the heavier arrow and a reduction of 4.9 lbs/ke and 10.1 fps for the lighter arrow.

The ballistics of the first one is a 417 grain arrow shot out of my bow at 294fps

This second one is a 351 grain arrow shot out of the same bow at 320fps
