Anyone see this video that has gained steam over on that other archery forum? Basically its debunking the statement that high FOC helps arrow penetration. I see a couple of issues with this guys statements and feel higher FOC does help penetration. Two reasons. One, more weight at the tip decreases flex along the shaft at impact, less loss of energy equals more penetration. Secondly, higher FOC arrows stabilize faster in flight, not shedding as much energy. This is of course going with the assumption that the bow is tuned to that arrow setup. Now, I will say I think we're overthinking this entirely too much and we're probably bordering on splitting hairs. Its the off season, its slow around here. haha
I watched the video and applaud his effort. It's only more fodder in the EFOC debate as it doesn't prove or disprove anything to me.
He most certainly doesn’t understand the principles of kinetic energy, B for effort though! Sent from my iPhone using Bowhunting.com Forums
If anyone has ever shot a slow moving trad bow then they understand the difference that high FOC brings to an arrows penetration. No debate. Sent from my SCH-I545 using Tapatalk
The arrows I am shooting out of my stick bows are traveling over 100 MPH , bows with draw weights ranging from 38# to 43.5#'s. Never measured fps with chrono. Don't know my FOC numbers. I like simple, I buy the properly spined arrow for the bow ( aluminum) based on using a 135 grn point, check to see if bareshafts group with fletched arrows, make minor adjustments. These arrows zip thru deer with a well placed shot. With all that's been said ., I prefer a flat shooting arrow, lobbing an arrow thru brush/ limbs , not.
FOC is often over rated among trad archers - but those tests are junk. For straight flying arrows into a uniform soft media - of course it wouldn't make a difference. The potential advantages of high FOC would occur if -the arrow hit the target at slightly indirect angle. This is more likely with a trad bow shooting off the shelf than with a modern compound set up. -the arrow hit something hard that redirected it inside the target. High FOC keeps more energy/momentum behind the blade. The only large animal I hunt is deer(with a trad bow) and you dont need to worry get good penetration on a deer. You just need a sharp broad head and an arrow with reliable structural integrity. But I understand why people hunting tougher game might want to use high FOC for what ever small advantage it PROBABLY provides.
It makes a huge difference. I shot my buck at 40 yards with a high FOC easton tortch, and man did it smoke him,
