rifled arrow shafts
 

I was talking to a friend of mine about how a bullet shoots better coming out of a rifled barrel. It got me thinking would having a external rifling on the outside of the shaft help the arrow out ,hurt its trajectory, or not do anything to it ?Just wondering or do i have to much time on my hands to be thinking of wierd stuff ? :DDon't answer that .Would spiraling the broadhead help ?

yes from what little i do know about the technical side of bowhunting, i have read that spinning the arrow helps stablize the broadhead and better flight. this is why they make helical fletching and also those quick spin vanes. JMHO but i dont think the "rifling" on the shaft would help spin the arrow, idk if it would hurt it either tho.

RE: rifled arrow shafts
 

helical fletching.....Thats really the only way to beeffective
Not to much windresistance on broadhead or shaft.

I purchased some new "turbo nocks" from the the bohning people at the eastern sportsmans show in harrisburg last week, they are supposed to enhance the speed of the arrow alot, its basically another way to rifle the arrow. I think they are the T-4 style but not sure, i'll post some info when i get a chance to try them..

RE: rifled arrow shafts
 

Maybe this has been brought up before, has anyone thought of how a spinning arrow effects broadhead penetration?

RE: rifled arrow shafts
 

if the arrow spins, it will stabilize the arrow, but it will also slow down ur arrows some.

RE: rifled arrow shafts
 

If your arrow was rifled and you used a whisker bisket rest where the riflings would actual contact the rest to make it spin it would work. But any other rest would not work the same. The bullet in a rifle contacts the riflings and that is how it spins.

RE: rifled arrow shafts
 

That has always been my understanding ..... anyway, a hard helical would do WAY mor to spin the arrow than any type of exterior rifling in the shaft IMO

RE: rifled arrow shafts
 

i agree helical fletching will get the job done better i just thought maybe it would give a slight advantage to the spin.

Think of the physics required to impart spin into an arrow.

The closer to the centerline of the shaft you attempt to generate rotation, the more energy is required to accomplish the rotation. It is more like a lever, the longer the lever given the same fulcrum to load ratio, the longer lever is able to place much more energy into the load.

The more offset or helical placement of your feathers or vanes, the greater leverage effect on the arrow shaft. Since the vanes are at the greatest distance from the center of the arrow shaft, they have the most to offer in the form of rotational energy. The increased suface area of the vanes(feathers) cannot be duplicated (force vs force)by any other arrowcomponent and therefore they are the most effective in producing arrow spin. This is because the fletching is in constant contact with air. This interaction is what produces the energy that we are talking about. It occurs the entire time an arrow is in flight.

Alas, the QuickSpins. They use this same principle of physics, but I have never used them. Ican control myshafts with helical or extreme offset fletching w/a drop away rest. No clearance issues and without the added weight of theNAP vanes.

And yes, all concessions have concequences. More spin = less speed. But what are we trying to achieve here, better accuracy at a slightly slower fps or just acceptable accuracy at blazing speeds?

RE: rifled arrow shafts
 

Ed, that is a good question....at least to me [8D]

Any takers???

Interesting! They already incorporate the concept in broadheads. The Thunderhead isn't rifled, but has groves that are supposed to keep it going straighter, farther. I do believe it works. Could do the same on some shafts and see. I bet they already have. I like mine polished so I doubt I'd be a customer if they did.

RE: rifled arrow shafts
 

You don't need "rifled" arrows, that is what the fletchings do. Besides the concept with bullets has the barrel rifled, not the bullets.

Even a slight offset on your fletchings will provide enough spin to stabilize an arrow.

it is not the bullet haveing grooves put in it by the rifleing that makes it spin, its the rifleing spinning it. I dont think putting rifleing on arows will make them spin at all and will only create drag.

hey huntinged, do you hunt Turkey Point, Rogues Harbour, or Carter in Northeast, MD.

RE: rifled arrow shafts
 

Yes I have, my cousin is a ranger at that park.

RE: rifled arrow shafts
 

Penetration should not change, but impact force will be much higher, think about karate, if you punch someone straight on it hurts, but they teach you to rotate your fist so you put torque into the impact, it hurts a lot more. I saw some pics and videos of these new "high spin" nocks I bought, they were awesome. The entrance hole looked like you shaved a 3" spot on the deer, and then punched a 2" drill into it... and the exit wounds were even better.

Im gonna test the new nocks as soon as the weather gets better... I'll be sure to post results.

RE: rifled arrow shafts
 

I dont think rifleing the arrow would do anything because a bullet isnt rifled but the barrel is to make the bullet spin. Now if your shooting the arrow out a barrel you might be on to something but I think that would make things a little more interesting to say the least.

RE: rifled arrow shafts
 

The same idea of an arrow spinning to stabilize a broadhead is similar to a baseball and pitching. A two seam fastball is spinning the fastest and getting the least air resistance because is it spinning against the least stitches so it goes the straightest and fastest. When I throw a knuckleball, I want the least rotation on the ball so the wind and air hits the ball and affects it so make it dance all over the place. If our arrows are dancing, consistency will suffer greatly and hitting anything with a broadhead would be impossible.

RE: rifled arrow shafts
 

why do you think crimson talon made their broadhead on the helical it stabilizes it and it cause the wound to not clot up i have wanted to try turbo nocks give me a review Ed to convince me

RE: rifled arrow shafts
 

They had a Arrows back in the 80's (I belive were called Excabibur's) that had air groves down the length of the shaft, but they weren't around long!
