energy question!!

[sureshot]

I have a question on kentic energy that I have been trying to figure out, I am a muzzy and thunderhead guy, I shoot at just about 75 pounds and 30 inches and use a fairly heavy arrow so I have no problem, the question I have is my daughter has a bow,prob set just over 40 pounds, a buddy has one at 50 pounds, problem is there draw length is short, what would you recomend for the best broadheads?? I talked to a guy tonight that owns a archery shop, he says the thunderheads and muzzys take alot of energy just to penetrate the skin, he reccomends on short draw length and fairly fast new bows with low poundage mech blades!I always thought the blades took alot of KE just to open but he says tests have been done with lower KE bows like kids bows were mech are reccomended! I would believe that I should go with the heaviest arrow broadhead reccomeneded for the bow, speed does not matter as much as penetration in my eyes, just wondeing if you ever heard about mech being better than fixed for low poundage short draw length,, thanks in advance!!

I would stick a Muzzy on that arrow in a heart beat, it doesn't take a lot of energy to penetrate especially witht that Trocar tip. the only mechanical that is designed for low KE is the Rage 40KE. My sons bow is set at 37 pounds with 25" draw length and is tipped with Muzzy's. I wouldn't worry about it. Personally, I've never seen mechanicals recommended for lower KE bows, they are always for faster shooting higher KE bows for the shear fact of the energy it takes to open the blades.

thanks exactly what I thought , this guy swears the total opposite though,

I'd use a true cut on contact head-Magnus Stingers, Slicktrick Razortricks, etc. Thunderheads and Muzzys still have to "punch" through hide, but I'd use those over any mechanical at those DWs and DLs. Good to hear you got the kids out hunting with you! Wish you all a safe and successful 2010.

I agree with that. Takes a lot of engergy to get that trocar tip on a muzzy to penetrate. It's designed to be a tough bone crusher. Stick with a cut to the tip, of if you want a mechanical check out one like the G5 Tekan. Flies like a dart and I like the operation of it, nice small cut-to the tip point with rearward deploying blades.

I remember reading a study that said a trocar tip or bullet-type tip takes about 20lbs of pressure to punch thru a deer hide whereas a COC head only takes 2lbs....big differance

I agree with that too!

Even still with a youth bow having 30 to 35 lbs. of KE, it's still enough to punch through the deer. Not arguing, just pointing out that its above the energy it takes to have a trocar tip punch through a deer hide.

The only way that I could imagine a mechanical out-penetrating a fixed-blade cut-on-contact head would be in cases where the arrow with the fixed blade could not be, or for some reason was not, tuned well and entered the deer in an improper axial orientation, and the mechanical was tuned and flying straight. Other than that, its pretty hard to imagine a mechanical head winning in a penetration contest.

True, but I generally like to crush a little bone along the way also, and not just hide.

Now see, if you shot as good as me you can shoot between the ribs and miss those rib bones. LOL:poke:

Haha! I'll remember that one! I'll have to order some .005 pins so I can put it right between the bones. I'm always learning

Of course, I've sent one or 2 over the years clean through without hitting bone, that didn't work out too good!
