My version of Air Archery

[Nomadic Pirate]

Hey Manny, Craig here. When Air Archery hunting, what season type is it considered? Bow or Air rifle? By the way, how is that pellet trimmer
working out for you?  Craig

Craig, the pellet trimmer is fantastic, precise and easy to use,.....Thanks


Well, here airguns are only aloud in Private lands,
so hunting regulations for state lands don't apply.

I bet there is a lot less bore friction with the bolts compared to a pellet and definitely compared to a slug.

As always your hunting setups are bad !!!. Aren,t we suppose to be dedicated traditional archers LOL.    Mike

You are soooo right , but this thing is so Kool, so Baad Azz

Anyway, I don't do target shooting with airguns,
but I get my target shooting fix by shooting 200-300 arrows daily, at the moment I'm shooting an Osage bow I made several years ago and usually take it hunting if I can once a week or at least once every 2 weeks

Manny there addition to the explanation....  Caliber cross section. Pound per square in translates to force. Acceleration =force x mass.
Cross section of 1/2" is .196in^2 . Multiplied by psi give Force pushing the arrow. Compare that to the area of the back of a pellet or slug. The arrow certainly has much less static friction (break away friction). The efficiency of acceleration offset compared to traditional projectile is why the energy is greater and the velocity so vastly different. Air consumption is greater since the larger tube is less restrictive  than a traditional barrel. Higher volumetric flow at the same psi. I'm not certain that the valve stays open longer or not.  I'd have to sit down and math the *(&^ out of it to be sure. I would imagine that if the tube were longer say 24in, those arrows would reach close to 700fps.  Supporting the broadhead in the center of the tube would be another hurdle  though. Any way you go about it , those are superior to any crossbow I've come across.

[Nomadic Pirate]

But.......

The arrow is actually shot out of the same barrel that shoots bullets and pellets 

The broadhead is supported in the center of the barrel by a conical aluminum insert that sits in the crown of the barrel.


The was increase in FPE and decrease of shot count also happens when I use the 190gr bullet compared to the 82gr JSB, and probably the bullet creates significantly more friction then the pellet.


But I love to hear experts try to crack this one, we can learn something every day

Hi Manny
  Great information on the Rex with arrows. If you could give me a little more information. I have the 19” barrel model and when you cut down the bolts do you cut the front and install a new insert for the broadhead?. And do you run with the end cap off to get to the barrel or just but the aluminum piece up against the end cap of the shroud.

     Thank you for any information.        Marco25

Marco, you have to make your calculations,

take the aluminum adapter off, see exactly where it sits in the barrel, measure how much it overlaps on the bolt, measure how much the bolt extends out the barre ( you can have the nock quite close to the valve when taking final measure )

then make your calculations, cut the bolt and re-glue the aluminum adapter.

[Marco25]

Got it. Thanks for the help Manny

Well Manny I was wrong I looked into the inline valve system and your right back pressure can cause higher dwell in this system and thus higher FPE output and lower shot count due to higher dwell I guess that explains a lot.

I must be getting a better understanding of how this stuff works because this was the first thing that came to mind when I was reading this thread and Manny posed the question.
Now I feel like I know just enough to be dangerous...

I’ve got the opportunity to pick up a Rex from the used market but I’m not sure of air bolts. It’s a 357 like Manny’s . Is there a magic formula for making your own bolts? I do have a lathe so making knocks and front guides shouldn’t be a problem. Any advise here ? I’m a complete newb when it comes to any form of archery.

Just buy the highest spine 6.5 mm carbon shafts,......( 3Rivers is a great supplier )

then cut to length ( if you get there either PM me or make me aware of this thread so I can give you a couple pointers )

get some high grade sticky velcro, make nocks and guides and you ready yo shoot

most people don't know that all FX guns are easily converted, with the purchase of a kit, to an "air bow" Pretty nice knowing that even a person's .177 dreamline can be very easily converted to an air bow that has no trouble taking big game with ease.

[Hobbyman2007]

Can someone take close up pics of what the nocks look like on the air Venturi bolts ? Better yet the whole bolt. Also what material do you think is used for the nocks and guides? Would PFTE work or is that too soft?

Not a fan of arrow kits or arrow only shooting guns,......I want my gun to shoot an arrow and immediately after a bullet.

Going to take some pictures right now for you

[Nomadic Pirate]

Here is my 2 arrow shooters, both with 14.5" barrels

[Nomadic Pirate]

and here some pictures of bolts, nocks and guides
