Arrow front loading question for the gurus

[muddyfuzzy]

i am shootin slick tricks now.
and ... Change tip to 125. Spine needed (.3778) how do get to .3778 needed??

shorten that arrow up, but it still don't think its a good fit.

shorten that arrow up, but it still don't think its a good fit.

it is as short as it is gonna get.

sounds like a trade off to me... flatter trajectory or better penetration.

guess I need to figure out how to miss the rib bones

[muddyfuzzy]

not with modern compounds that make good speed. you can build arrows in the 420-450 grain range that still have decent trajectory, more FOC and superior penetration and forgiveness. Some quack on here runs around calling it TAP or something like that.....

I know that quack.

thanx guys,

I'll look at the GT charts tonight after work.

[enewman]

If your using charts then use Easton bow hunting arrow chart. This chart has adjustments for ibo. It goes to 150 gun tip or adjustments for going heivier. Also if your broadhead is longer then a field tip. You may want to go one mark to the right.

That chart with 125 tip put you in j. That's 340 spine

[Huntindad]

Thanx,
kinda looking like a 340 spine with possible weight aded.

Will look at that chart in a bit.

[Huntindad]

I got some weights. Got my bow restrung and went out and did some shootin. I put 2, 20 grain weights in a 400 spined velocity and a 340 Hunter XT that I had. I shot several groups and did not have a noticeable difference in penetration.

It did look as though the non weighted arrows penetrated a little more. I did notice a drop in impact point.This was a brand new target. I will shoot some more today. I'll experiment and see what combo seems to be a better set up for me.

You cannot use targets as a penetrate test. Depending on what type of target will give you different results. Lots of targets are design to stop by friction. This means a lighter faster arrow will penetrate deeper then a heavy slower arrow. But I promise you that will not be the case on an animal if bone is it.


Also the 400 spine with the extra 20 gn is weak. You still can tune this. And get it shooting. Where the problem come in is when it hits an animal. The arrow will flex more. It will whip. This is what hinders penetration.

If you are really looking for max penatration switch from slick tricks to a 2 blade as well. You will definitely see difference in penatration.

[Huntindad]

Thanx guys...

I may consider a 2 blade coc. Or possibly a longer designed broadhead...one with a longer less severe angle.

Agree about the whipping action.
