Bought a dozen new arrows and was kind of surprised to see that the older ones consistantly have 1" more penetration into a bag target at 20 yards than the new ones - I mean 12 out of 12 shots. These are suppose to basically be the same arrows - any idea why the difference? The new ones do fly better and are more accuurate though. :confused2:

2 year old arrows:

• Gold Tip 5575 Hunter carbons 27.5"

New arrows:

• Gold Tip Expedition Hunter 5575 carbons 27.5" (direct replacement for the Hunter model)

Both with 4" feathers 3 degrees offset right shooting the same 100 grain field-tip. Inserts appear to be the same but I believe the nocks may be different.

what is total wgt of each arrow?

the older gold tips are heavier, therefore they will penetrate deeper....i think generally speeking they are going to be 1 to 1.5 grains heavier than the new shafts

Your right - according to the spec.'s the older ones are a little heavier. So, I ASSume that since the new ones are lighter I picked up a little speed but lost some penetration power which could be offset with the right broadhead.

Sound right?

 

[PA.JAY]

sounds right too me ! more weight more KE.

 

[metalarcher]

More weight more momentum...

M = M*V

Less KE as the arrow goes slower.

KE = M*ZV^2
