I picked up an 80# pull, with both aluminum shaft and later all-plastic bolts. As mentioned in earlier posts, they are target point tipped, and about 6-3/4 in. overall in length. Set up my plastic, broadhead backstop, put it (foolishly) near the front gate (chain link fence, with the aluminum slat privacy panels) ... stepped back about 15 yards, took aim and let one fly.

The bolt penetrated this 4 in. thick backstop, and cleanly pierced the slat (about 2 inches behind the backstop), by about an inch and a half. I packed everything up and put it away until I can get to the archery range, which it will be much safer! LOL

Did some web searching - there are NO commercially made broadhead bolts available for the Pistol Crossbow. The shaft for the commercially made target bolts are 1/4 inch diameter (both aluminum and plastic shaft).

*** Enter the craftstore! **** Gotta love that place!

12 in. long 1/4 in. diameter wood dowels sell for about $2 per dozen. 1/4 in. diameter glue-on field points are available online for "youth archery". Bought a dozen of them. Made a fletching jig out of a wood block (dremel tool to make a groove for the shaft). Bought a few strips (1/8 in. by 3/4 in x 2 ft) of balsa wood. Used the commercial bolt's fletch to make a template - but made the over-all length 4 inches due to the near doubling of the shaft length.

NOTE - once you have the first bolt fletched, ensure that the fletching can cleanly pass through the front guide of the pistol crossbow. You may have to trim it a bit.

Used Elmer's brand exterior carpenter's glue (thin layer, let it get tacky for a minute or so) on the inside of the fletch. Mark off 5/8 in. from the back of the shaft, place the shaft in the groove. Place the fletch on either side of the shaft, balanced on the jig (pistol crossbow bolts only have two vanes). Be sure that the back end of each vane does not exceed the 5/8 inch mark. Use rubber bands to hold vanes in place. You might need to insert toothpicks beneath the front and back of the shaft so position the vanes on the center of the shaft diameter (eye-ball it). Wipe off excess glue. Let dry for about 5 hours or longer.

Once dry, remove the rubber bands. Add glue to fill in any gaps betweeen the vane and shaft, and put a bit on the front and back ends, smoothing it down. Let dry again. Once the second drying has completed, take 100 grit sandpaper to smooth off any dried glue. Sand the outside edge of the vane to a point (taper away from the shaft). Sand the back end of the vane smooth. Sand the front end of the vane (right side top) to make an airfoil (like an airplane wing). Rotate the bolt 180 degrees, and do the same on the other vane. Having this airfoil effect will enhance the bolt's flight, causing it to spin as it flies.

After the sanding is completed, paint the vane and shaft (I used flat black for the vane, to match the commercial bolts, and primer gray for the rest.)
Once the paint is dry, put the front tip of the bolt into a pencil sharpener to pit it. You may have to sand it a bit more, so that the pointed shaft fits properly into the glue-on field point. An archery "hot glue" can be purchased online for this purpose. If there is any non-painted wood showing, I used a permanent marker to fill in that gap.

You now have an awesome looking filed point bolt for the pistol crossbow, which should cleanly dispatch any small game the the target bolts can't handle.

I found some 5/16 inch glue-on Muzzy brand 2 vane broadheads ($22 / 6) !
5/16 inch by 12 inch (10 per pack) wooden dowels at the good old craftstore!
Same process as above (but since the shaft needs a longer taper - I twisted a small ... 3 in. x 5 in. piece of paper, into a tight cone, inserted it into the broadhard back end, and allowed it to expand to fill the void. Secured that with a wrap of masking tape. Marked the end of the broadhead with a pencil, completely circling the paper cone. Removed the now perfectly fitting paper cone, cut off the excess paper from behind the masking tape, and sealed the paper with clear nailpolish from the wife. Two coats, and now I have a perfect form to use on the 5/16 inch diameter shafts, to sand the tip down so I'll have a perfect fit for the broadhead tips. (Used a dremel tool to make my life easier, since this is longer, and the pencil sharpener is not making a long enough taper.)

The end resulting hunting bolt will be able to take out a deer (if the shot is properly placed). 85 lb. pull pistol crossbows are supposed to be available, and I am told that if you give the string several twists before connecting it on the prod, you may be able to get an additional 10 or more pounds of pull.

The 12 inch long broadhead and field point bolts extend past the front of the pistol crossbow by a few inches. That's fine for me. If you don't want that, you can cut the shafts down a few inches shorter before putting on the points.
 
Testing

I should be interested in seeing how your initial range trials turn out.

Maximum effective range, maximum accurate range (accurate to mean a group small enough for reliable repeatability).

I've had a couple of the pistol crossbows. They never felt particularly safe, and I was never able to achieve acceptable accuracy.

Perhaps you will do better.

 
1. What JShirley said
2. Those wooden dowels will quickly find their limit with an 80# draw on such a short draw length. So, be sure to examine them regularly for cracking along the grain.

Remember that weapons evolved away from handheld with regard to archery because of material limits and efficacy. The sight radius and overall projectile weight of the pistol crossbow make it immediately less accurate and less penetrative than a regular crossbow, which itself is really not so great at longer ranges or with larger thick skinned game.

However, the new black in survival/neato weapons is the slingbow. Perhaps you'll create a new cool thing for people with all of this experimentation. Pics?
 
I saw pistol crossbow arrows with broadheads back in the late 80s in South Africa. They were plastic arrows and the broadheads were a one-piece cross-head which was little more than three crude fins of metal that were sharpened.
These pistol crossbows just don't have the oomph in my opinion to be useful for anything but really close range shots on small animals. Might be a better option to get one of those reverse arc compound crossbows and get proper quality broadheads.
Here is one example:

Or perhaps a different type of compact crossbow like a twinbow:

You've made a lot of assumptions on performance without the testing to back it up.

It is possible that you have something there, but be careful too because you're using materials that are not intended for the purpose. Wear eye and face protection during your testing in case you have a dramatic failure. We'd rather you be in a position to learn from any mistakes than to have a new cool nick-name (Scarface, Lefty, Pirate Fred).

I don't want the guy to get hurt or anything like that, but Pirate Fred is a pretty rad nickname...
 
Good for him, but I can't think of a weapon I would rather have less than a crossbow pistol, toy or not, when it comes to defending my home. Maybe a Nerf sword or something, but even that might be a close contest.

The basic problem with that statement is that it seemingly justifies that since the guy you know used it effectively, it must be an effective weapon. That's just not true. That's like advising someone to buy a lottery ticket in because a guy you know won the powerball one time. Yeah, it could happen, but it is unlikely to a extreme degree. Now, I hasten to add that I doubt that is what you were trying to say, but if so, we are in deep disagreement.

The fact that it can do damage, and even theoretically kill someone in no way whatsoever recommends it as anything more than a toy. A serious toy, no doubt, but a toy.
 
I agree it wouldn't be my weapon of choice, but it's what he had on hand.When the thug was able to finally get the door open, he attempted to keep the homeowner from getting the door closed again by using the old Three Stooges expedient of putting his foot in the door....my buddy proceeded to nail the bad guy's foot to the floor with a standard target point pistol bolt.After a lot of cussing and tugging the BG was able to extracate himself and took off running/hopping down the road.This was about twenty years ago when the pistols were still an aluminum body, and not plastic, and the bows seemed like they were a little stronger, but anyways, it worked.
 
Thank you all for the fantastic feedback. I live about a 20 min. drive from a County owned free outside archery range, and plan to test the bolts there (once I have the broad head bolts finished), when no one else is around! (Safety first) I do have a sling bow, but was a bit disappointed with it (might need to make some modifications, as it too is home made).
I will check the web links posted, and I will check each bolt before shooting for possible cracks / splintering. Thank you.

I do have photos.

Had to make a quick comment ... I'm just a poor working stiff. $1.1K to $2.8K for a crossbow? WOW! They are incredible, I must admit, but WAY out of my price range (thus the pistol crossbow).

Just a thought: copper pipe caps on the back end would work to keep the string from damaging the bolt back ends - but would it disrupt the aerodynamics and balance too much? Current center of gravity almost matches to scale, that of the commercial aluminum target bolts.

Does anyone know if there are PVC caps in that size (0.25" and 0.3125" ID ... lighter than copper and can be sanded down, tapered, flush to fit) ?

Should the broad head be in line with the vanes (parallel to them, or it doesn't matter) ?

Thanks again.
 
question....

Is it even legal to hunt with a pistol crossbow where you are? That 1.1K for a regular crossbow might seem cheap in comparison to whatever fines you might face if the game warden catches you if it is not a legal means of take.
 
What ever cap you use, it mustn't be a greater diameter than the shaft of the arrow, otherwise the arrow won't sit parallel to the crossbow track. That's dangerous.

The fletchings don't have to line up with the blades on the broadhead. Think about it, folks use three fletchings in combination with 2, 3 or 4 blades all the time and they don't have issues.
 
Thanks again for the feedback. Rather than "legal", let's use "allowed" - I know of nowhere on the planet where pistol cross bows for hunting are allowed. 80# and greater are a relatively new thing to the pistol crossbow world; most places require a minimum of 80# pull on longbows for "humane" hunting. So, like the atlatl, legislation just hasn't caught up to technology as yet. This too may be a reason why no one sells broad head bolts for them either. Like blowguns and slingbows (also not allowed ?) you need to stalk the game and get really close to get a one-shot kill. THAT is the sport to me, not being able to take the critter down from a quarter mile or more away, so that without high power magnification you can't even see your quarry.

I greatly appreciate all the feedback. It will be a few more weeks before I can get to the archery range to test them out, but I will post back here with the results (I'll remember to bring a camera for documentation ... I am a terrible shot, so don't get your hopes too high)
 
There's not a single place in North America where 80# draw is required for hunting with a longbow. Less than 1% of longbows used for hunting are over 80#'s.

If you don't know anything about wood arrows you need to familiarize yourself with nock orientation relative to the grain and grain runout on the dowels. If you get this wrong you just might end up with some large splinters in your hand.

Glue on nocks are available in most sizes and will work on the "back end" or nock end.
You can also cut self nocks and reinforce with sinew or kevlar thread or just cut down a carbon or aluminum arrow and use threaded inserts.

Balance point on the arrow or bolt means nothing. Many of us longbow shooters will use an arrow with weight 20% - 30% forward of center.
 
Went out to the archery range this weekend to test out the pistol crossbow under controlled conditions. Brought along a self-healing 3 in. thick, 20"x20" backstop. Centered a CD (12 cm) and drew a ring around it as a "bullseye". Shot the cheap plastic 6" bolts from 30 Yards. OK, I am no expert with ANY kind of bow ... but I did come very close to that 12 cm ring most of the time. However (caveat emptor) - the windings on the bowstring became undone after less than 2 dozen shots. Need to take the string off and use waxed dental floss to correct it - happened at the center as well as the right side loop.

Did not test the homemade bolts yet - but found that if I go to Sears hardware and buy the plastic screw protectors for 1/4 in. and 5/16 in screws, they fit perfect - need to be glued on - then the rounded tips cut off even with the wood. Haven't tested them as yet - need to resolve this bowstring issue first.
