Gold Tip Laser IV arrows (Kinetic)

[sumner4991]

Arrow type, fletch type have nothing to do with launch speed. . . .. But I want to see a 550 grain arrow luanch from his Exocet at 295 fps.

I was thinking the same thing . . .but, for me, this falls into the "who cares" catagory.

Anyway . . .nice heavy logs are a good choice. Like everything else, there are trade-offs. If the heavy hitters are accomplishing their goals, then that's great.

I get great accuracy, great penetration, and dead deer with a 408 grain arrow out of my Exomax.

There is no one way path in archery . . .there are several paths that end at the back side of a deer on the ground in the yellow wood.

I dont take bad shots but I had a buck last year change course on me while squeezing the trigger...... Which resulted in a shoulder shot with like 4-6" of penetration. This was a 400 grain arrow. After that I made my mind up to go with the heavier arrow with cut on contact heads and if that happens again in my life time I should have the penetration to the vitals and not wound the deer. Keep in mind I keep my shots at MAX 35 yards, most of my shots are about 20yards.

Being new at bow hunting, I have a few questions. Wouldn't the broadhead design have alot more to do with penetration rather than the weight of the arrow.Example size of broadhead. Being a rifle hunter for years, bullet designed played a big part on weather or not the bullet went through bone, not the size of the bullet, example hollow point verses national matched brass point. Also having a mag gun with crazy speeds seemed to cut through bone alot easier than non mag guns. Doesn't a heavier arrow shoot alot slower, I know were talking twice the mass here as compared to a rifle bullet. is that the reason to get a heavy arrow? Thanks. Ps. secret, dammmm nice shooting.

Hi,

I think most would agree that broadhead design has a lot to do with penetration but a "lot more" than weight I just don't know. How would you figure that out? Many, I suspect, would/could argue that momentum is a better measure of an arrows ability to penetrate vs. the KE. Weight if I'm not mistaken ups the momentum vs. speed for KE.

weight over speed will get you higher KE/deeper penetration....two arrows made with same brand broadhead but with different weights....

arrow "A" 20" alum 2117 (240gr) w/ 100gr slick trick, alum insert (25gr), 4" vanes (27gr), alum nock (25gr) = 417gr

arrow "B" 20" alum 2117 (240gr w/ 125gr slick trick, brass insert (110gr), 4" vanes (27gr), alum nock (25gr) = 527gr

arrow B will have higher KE over arrow A traveling faster then B....weight gives you deeper penetration as it has higher KE then a lighter faster arrow....like the saying goes "give me a heavier more stable arrow over any faster lighter arrow" .........bob

plus also that's like a commercial i seen on tv with big wide 2" and 3" expandibles vs small fixed head's trying to say they penetrate deeper then the smaller fixed head's....but i bet they used a heavier arrow with the expandible to get deeper penetration in the gel block they had used....my thinking is there is no way a huge expandible with more cutting area/surface will penetrate deeper then a smaller fixed head of the same weight in the same weight arrow with less cutting area/surface, it is simple physics.........bob

Heres a penetration test that I did, Ive post this before and yes we don't hunt tractor tires, if you look you'll see the ones that didn't make it thru both sides, anyones favorite BH there, all shot from the same bow, same distance. the weight of three was 500gr, the one that went thru was 352grs with COC bh. 352grs, 350fps=95.77KE. To me they all get the job done, theres no wrong with lite or heavy, it's just I like speed and the only reason I got a 225lb is because they don't make 250lb xcal.

If no one believes bob heres the math
295fps x 295fps=87,025 x550=47,863.750 divided by gravity constant 450,240=106.307 KE

Like I said, it is not the math I doubt. I know the formula for determining KE. Anyone can plug numbers into a formula and get an answer.

Again, for those who seem to have difficulty understanding, it is the velocity I am doubting. How does a 200 lb Exocet generate 295 fps and 106 ft.lbs. KE, with a 550 grain arrow...AND with 15.5" of draw length? My own Vortex (also a 200 lb bow and 15.5" draw length) shoots a 450 grain arrow (that's 100 grains lighter than Bob's 550 grain arrow) at 298 fps, for 89 ft. lbs of KE. That's quite a difference!

For fun, I built a 560 grain arrow with the heaviest components I could find. Results: My 200 lb. Vortex shoots a 560 grain arrow at 276 fps., for 94.7 ft.lbs KE.

Now, I understand that not every bow will shoot the same, not even bows of the same model, but the velocity and energy of Bob's Exocet (200 lb., 15.5 " draw) is on par with an Exomag or Equinox bows (225 lb., 16.5" draw lengths)....AND his bow is doing this with 1" less draw length???

Arrow type, fletch type have nothing to do with launch speed. If Bob's bow is pushing a 550 grain arrow at 295 fps., then I want to see it! I am willing to eat crow, and bow down at Bob's feet and tell him I am not worthy to speak with him again. But I want to see a 550 grain arrow luanch from his Exocet at 295 fps.

Man let it go!! Last thing we need on this forum is another pissin contest!! If bob says he's shootin 295fps then I believe him...got no reason to doubt him!! It doesn't change my life either way!!
I chrony my vortex (200#) last weeknd ...393gr arrow shot 314 / 314 / 315 some may believe it,some not...could give a rats ass either way.

What i like most about this shaft is when it cuts through 30+ mph winds while hunting!!!! and you dont even have to put a 1916 shaft inside your shaft to achieve this!!!!!!Gold Tip Rules!!!!

Did you try the COC broadhead with the 500 grain arrow?

Yes I did, the results were the fletchings were inside the middle of the tire, more penetration,
what I want to do is put the other bhs on my 2114 and see how that works, don't want to put out 90.00$ to see? Like I said they all get it done.

I know I would get sea-sick in a tree stand with 30 mph plus winds

arrow B will have higher KE over arrow A traveling faster then B....weight gives you deeper penetration as it has higher KE then a lighter faster arrow....like the saying goes "give me a heavier more stable arrow over any faster lighter arrow" .........bob

....

And ALL will go through a deer like a hot sharp knife through butter. You guys are talking about penetration like you can't get your arrows through a deer. I don't see the big deal.

I've had very few arrows not make the trip all the way through(even with my Bear Whitetail Hunter) a deer . . and all those almost made the trip and still dropped the deer. For the most part, it doesn't matter. Sure, there is a chance . . .if it worries you that bad, then shoot a 7MM.

Seriously, it's not enough of an issue to get your camo in a wad.

[bob1961]

no camo wads here ....just stating what i hear and know bout penetration and speed with KE....my arrows have no problem blowing through deer even the 50 yard shot i found 20 yards past where the deer was standing .......bob
