penetration with a 30#@28" recurve

[trashwood]

i find it interesting that a 3 blade Woodsman penetarted as far as the 100 gr Stinger did.

I haven't checked Texas laws lately but at one time the law stated a 40# bow.  I had no idea what that ment.  40# on the legend, 40# at my draw, ??????. so if that is still a law I guess I wouldn't use the 30#

Now dang it Rusty.  Knock it off.  Your just going to stir the hornets nest with your dang high tech 30 # bow.

LOL

Could it be that all bows are not created equal. .. . hmmmmm.

[trashwood]

shoot man when I take that bow out in public I have to put a sack over it.  Samick Mizar riser, limbs, string, button, rest to my door for $201.  that there is 1980's high tech  

now where near the $1000 riser and $700 limbs of today tech  

it would make a fair hunting bow with a little spray can of paint and some string silencers but this was about penetration of a 30# bow.   I got to admit I was kinda suprized at the penetration I would have never guessed.

ya should see what my 46# samick extreme bf limbs do to the foam block

if you ever wanted a lesson in slim BH penetrating better than wide short ones....that is the bow to do it with.  90 gr first cut would not make it thru the block (shorter and wider).  Woodsman 3 blade had most lenght of the blade and shaft sticking out the back, beat all the rest.  don't have clue why a 3 blade would out penetrate a 2 blade.  least I saw it with my own eyes ya'd of never talked me into that notion      as I recall it was not so in Dr Ashby's paper ????

I can ask the Doc, he's in the other room, but my guess is a 3 blade relieves the pinch on the shaft in the foam better then a 2 blade. Meat doesn't behave that way, it opens up. I'm not familiar with the Stinger but he has said the Woodsman will out penetrate some of the wider 2 bladed heads...O.L.

[O.L. Adcock]

Aw..I just looked at the Stinger photos..That darned rivet is bad news!   ...O.L.

[MikeW]

All I see is the Stinger,nothing about the Woodsmen.

[trashwood]

O.L. I agree.  I don't have a clue if penetration in foam sheets equates to anything other than penetration in foam sheets.  It was interesting though and was a bit shocked at how the 30# compared to heavier draw weights.

for me the worst thing about a 30# draw bow is tring to get it off my fingers.  have to use a lot of talc on my tab    

BTW the stringer blades are held in by two screws thru the ferrell.  it looks like a ribit in the photo but it's a screw.  don't know if that is any better or worse.  have taken several smallish pigs with them but the shots were good shots.  only small ribs had to be contended with.

I'll just throw this out there.


How many different shots did you take?


I've not worn mine out enough yet but I've shot into some foam-layer targets where even with a fieldpoint you'd get 6 different penetration amounts with 6 of the same arrows from the same bow. The nocks were all within a few inches of each other, but definitely not even either.

Usually, the closer to the bullseye the deeper they went   :D

Mike - i shot the woodsman later than the pics were taken.  first cut, stringers and woodsman were all i tried.  

of course I think the 30# that was being talked about was less than a 28" draw which is my draw.  have no idea what the difference would be nor did i try to test for it.

i was just set back about the woodsmans penetration as I had always believed the old saw that 2 blades would penetrate better than a three blade.  still don't know it's not true in meat.  we will have to go with Dr Ashby's info.

soilarch - test was far from extensive.  I have three different block targets like the above.  all have been shot up a bit.  I tried to pick spots that were not shot up.  I measured the penetration of 8 shots with the stinger at 13 yds.  the average distance at the back was 1&1/4" on the 8 shots.  didn't measure the woodsman but shot it a lot.  i think the kurly wings stablized the woodsman better at distances greater than 15 yds.  at 22 yds the woodsman on the pictured 30# bow would no longer penetrate the block.  didn't test to see at what the exact distance was it stopped.

again i must say I am only say that foam is foam and may have no relation to anything else.  I would personally not shot a 30# hunting as I sho0t the 45 - 50 pound bows more accurately.  your form and release have to be spot on to get good groups out of light draw bows         it is great form practice

[trashwood]

to compare shooting with samick extreme bf holding 46# on fingers with 520 redlines with 1&1/8" of 2013 footing and 125 woodsman will put over 6" of shaft and BH out the back of the same targets in not shot up area.  if shot into center, the shaft ends up stuck in the wall of the shed behind the target.  arrow weighs 405gr with 3 x 4" quikSpin vanes.  arrow is stable and in the groove to 35yds as far as I have tested the rig.

I had some funny tests last week myself.  Took quite a few different broadheads and shoot them into full pumpkins.  

  SilverFlame and BearRazorhead were the best and almost equall in penetration.  This was not really a surprise.  But a 3" expandale out did both a Treeshark and a 4 blade stinger.  The Thunderheads a 3 blade head was also very high.

[loco_cacahuate]

there is no weight limitations in Texas now.

[Shawn Leonard]

I would think at some point speed and light weight would penetrate better than heavy and slow. 200fps. with a 300 grain aroow wouls outpenetrate 130 with 550 grain arrow in other words, yes? No? I like speed and weight, like 500 grains doing 200 fps. Shawn

[trashwood]

Loco - thanks, I should keep up better with the TX game laws.


Shawn - I am sure that speed and light weight would penetrate better at some point than slow and heavy at some point.  I am in general less theoretical and more practical.  As we well know the amount a varibles, form faults, and general mishap in hunting can trump theory every time.

i try to not live too close to the edge.  46 to 49 pound draw for me has done everything I have ask it to.  I must admit that I am shooting pretty hot recurves usually.  I think i'll just stay with the little margin of over kill I have going for me

[trashwood]

I checked the state regs and of course loco was correct   .  I camoed the bow, quitened it down and packed it and it's arrows up as a second bow.  I'll talk to Jason and Wingnut and see how it's shooting at camp (we are going deer hunting this weekend, leaving here at 7:30A).  we well see what we see

Doesn't surprise me at all.  My oldest son killed a javelina with a 25# recurve shooting wooden arrows with Zwickeys when he was about 8 years old.  Now he shoots a 73 lb Brack   :eek:

It doesn't surprise me that the Wensel out penetrated as I have seen the same exact thing.  Meat is not going to somehow slow down the Wensel more that the 2 blade. Not sure why the comment about meat not reacting that way cause it opens up when there's lots of contradicting data about narrow shafts penetrating better due to less drag.
