Another Penetration Question......

[slayer1]

I have a 65lb 64" Dwyer longbow. The only arrow I can get to fly out of it is a GT 3555 that weighs 545 grains.(8.4gpp. Its tipped with a 160 grain simmons landshark. My question is this. What type of penetration could I expect if I hit rib bones on a deer? I have already taken a doe with this bow, the arrow happend to go between the ribs on the entry and exit. The arrow was stuck in the ground on the other side. I was worried about the penetration I would get by not being at the reccomended 9gpp.(I Have been paying attention all the talk on here,around 9gpp). I tried adding 40 more grains to the arrow but it had a little tail wobble in it so I dropped it back down to the 545. Since the season is already started I dont have the time to experiment to much with other arrows. Do you guys think I am just splitting hairs here?

You'll get the same result if you hit ribs.  The biggest deterrent to penetration with your setup, is how hard the ground is after the arrow passes through the deer.

Slayer.....in reality,,,  545 grains is  9 grains per pound for a 60 pound bow and they will put it thru a deer cleanly all day long, no reason yours shouldn't.

Well, if you were shooting a 45lb. bow then everyone would tell you that at 12 gpp you've got a "heavy" arrow set up and should be just fine.  Can't be worse coming from a 65 pound bow.

I have shot deer with bows in the 50# range and a 8pp. arrow and have had complete pass thrus. On deer size game I feel guys worry a bit too much about penetration, as long as ya hit them behind the shoulder and not in it, 8gpp. form 40-50# bows is fine. Shawn

Shot a 700lbs+ bull elk this september at 30yrds w/ a 66lbs @27'' draw bow w/ a arro w/ 160gr ace.Total weight 560grs.Went thru the shoulder blade.Broke a rib under the blade and went between the ribs on the opposite side then buirred under the hide.
If your setup is tuned right.You should have no problems.

Here's what I did...

I shoot 74 pounds at 26".  I needed/wanted HEAVY shafts.  I had Bob Burton, of Whispering Wind Arrows make me up some hard wood footed "Hexi Shafts".  With 135 grain Magnus, they weigh 640 grains.  Bob is, in my opinion, the best arrow smith alive...and I MEAN that!!!  He worked with me on spine and I now have BEAUTIFUL WOOD arrows, heavy, and they fly like...well, arrows!

Since I went to this combination, I have taken well over 100 critters and performance and penetration are FLAWLESS!

A lot nicer looking than carbon and wood is a LIVING thing!

Slayer, don't worry about it. With that set up you can shoot through a deer easily, as you have already seen. Gary

Slayer,
I think you will find a lot of dead critters in your wake with that set-up. Penetration should be excellent.
