2 arrows/different speeds??

I need some help here from you techies.

2 of us were out shooting today. We are preparing for a boar hunt. We are both going to change to carbon arrows, but today we were each shooting our old aluminums. He was shooting 2413's and I was shooting 2219's. Just for kicks, we shot a few times with each other's arrows. My 2219's seemed to fly much faster than his 2413's, no matter which bow they were shot out of.

Our arrows are the same length with both having 100 grain target points on them. We obviously don't have a cronograph, but we both agreed that the 2219's were faster.

Anybody have one of those programs that would tell us the truth??

Thanks, Kev

Better try them through a chronograph. 2413 arrows are several grains lighter per inch than 2219's and will be faster.

Yep, I realize that the 2413 is a lighter arrow, but I still think the 2219's are flying faster.

Kev. If your 2219's are faster then the 2413's the stiffer shaft is closer to perfectly tuned than the lighter. The smaller diameter of the 2219 changes the center shot, nock set height by .002 and of course the spine or deflection. The 2219's are coming off the rest perfectly where the lighter, 2413's are correcting before perfect flight is attained. The adjustment in center shot and nock set height for a perfectly clean release is minute. Just one twist of the nock set on the serving or 1/16" in center shot can make a big difference in arrow flight. I would suggest you adjust your nock set up just 1/2 to 1 turn on the serving. This should adjust for the .002 in arrow diameter.

To check which is faster w/ out a chrony.
Shoot at a 20 yard target w/ your 20 pin. Then step back to 30 or 40 and reshoot, but still using the 20 pin.
The arrows that consistantly group higher from the further distance are the ones flying faster.

Good, low tech solution Dave.
I even notice a smal difference in point of impact at 10 yards (my basement), but at longer distances it would be even more noticable.

Hey Mainehunt...
Are they fletched the same?
If the heavier arrow has feathers, and the lighter one has vanes, that could make the difference when combined with what Sniper said about tune.

Nope, fletched the same.

Now it's over, we both bought Gold Tip Hunter XT's last night.
