25 cal air bolts

[Raden1942]

 So I am trying to design some homemade air bolts for my 25 cal talonp. I do not have a lathe but would like some ideas on how i might make some for hunting maybe pig size animals. Im not really going to hunt with them but like doing proof of concept stuff. Would love your ideas.

Micro diameter carbon arrows are 5mm (.20 caliber). I would start with that and turn a collar for the front and rear to ride on the bore. Leave them long enough for the outserts to hang out the front of the barrel.

This subject has been breached before (excuse the pun). In order for any arrow-shaped projectile to fly straight, it must have some sort of stabilizing feature, just like pellets do. In the case of pellets, it is the skirt and the spin of the rifling. An arrow—bolt—must have a skirt of sorts, and it must spin—feathers, or an assemblance of same. If you can figure out a way to wrap those around a shaft, small enough to fit in a .250 ID barrel (or even a .257), you'll make a lot of money. Oh! Should I mention... If it were possible, it would already be done! 

On the subject of pigs. If you're careful about shooting them in the upper forehead, under 50 yards, using a .25 caliber pellet gun, capable of about 45 FPE or more, you all come on down! 

Nice thing about head shots on pigs, you don't lose any meat. Unless of course, you're into pig brains and eggs!

So the daisy 880 barrel fits perfectly inside 2219 crossbow bolts. When I had that gun, I was always trying to figure out how to fix the 880 barrel to the Talonp barrel. I thought of maybe threading the barrel and making an adapter. 

 

[Raden1942]

Maybe I will weld a daisy 880 to a 12x20 unf fitting and thread it on to the end of a donny fl adapter and seal everything up then slide the arrows over

What about some arrow fletching that is on something like a loose ring around the bolt that when loaded into a barrel remain out of the barrel near the arrow head, but when fired slide to the back naturally? When the fletching slides to the back it should slide into some type of thing that prevents the fletching from spinning so that the fletching makes the entire arrow spin instead. 

 

[Raden1942]

I was thinking like a bunch of string like the ninja darts have. It could double as a stability thing and the seal to push the dart but with a small arrow head at the end instead of a spike.

Why not make a tube "barrel" like the FX Verminator uses?

Get a tube about the size of a standard arrow's I.D. and solder it onto a fitting that fits the Talon. Put an O-ring on the muzzle end to seal the gap if needed.

There's probably a patent involved so don't try to sell them.

I have read that many use brake line, you would take a breech barrel end an make an adapter to mate the brake line tubing, then you just slip the arrow shaft over that

the arrows might need some help in the tip area so you don't blow them off but this R&D right

with this setup you have fleches left on the arrows

or like pinball stated

hmmm,,I don't know if this should be a concern,BUT, would there be a chance of blowing out any seals due to an increased backpressure from firing bolt from an air rifle? Or hammer bounce or something of that nature?

An arrow sliding over the outside of the barrel is always going to be more efficient than a bolt running through the bore

So I actually had a solution for this but I’m looking to improve it! So basically I remembered those .22 gamo shot shells and how they had what essentially looked like a shell which would be held in place by a lip that catches on the back of the barrel. Then I tried essentially making one with a metal tube (for inside the air bolts) that was 5mm or 5.5mm OD so that the .25cal bolts would fit over it when loaded into the barrel (a break barrel obviously because I didn’t want to muzzle load for multiple reasons. I also tried this using non-metallic tubing since I wasn’t muzzle loading the bolts and this had better results in a ton of ways — the only problem I had with it was that they would fall apart easier since they had to be glued to the lip (thin metal washer seemed to work the best but they had to be carefully picked out and spaced — maybe someone has a better idea for this?) as for the tubing — I did also make sure to have bolts with fletching which I could twist rotationally into the barrel to match the twist rate and direction of the airgun (flexible fletching).



And I do think that a muzzle loading option would work for normal PCP/HPA .25 cal pellet guns too — non-break barrel — but it would need a rigid thin metal inner-tube type attachment that’s tapered/beveled inward on the end so that you actually can reliably have the bolts slide over the tube. Also because you would need to weld it to the disc in the back which would make it act like a cartridge (similar to the 22 gamo shotshells). But also, so you can put o-rings over the very back of the insert to keep it centered inside the barrel and prevent air leakage. However, every single airgun is different and would have different spacing needs. I would like to see if anyone has some suggestions for these ideas and builds though! I personally like it this way since it’s a drop-in/drop-out solution for airguns that people already own.
