Hello all! To those of you familiar with medeival handgonnes, do you know what the average caliber for one would have been? I am thinking about having one made for me. They look so fun and interesting, and I want to be sure I am getting one with the "correct" caliber.

Thanks so much everyone!! :D
 
I'm sure more people in the "Pre Flintlock" forum area will be able to answer your question than the ones in the Smoothbore area so I'm moving this topic there.
 
I've only seen photos, seems " bores around" or "about 1/2 inch or 14 mm" is often the caption.
Zonie I don't think there were any rifled hand gonnes :rotf:
 
'morning,

I used to have one. The looks I got at the range... :grin:

Anyway, mine was a .50. I went with that because of the availability of ball. It has gone to a new home, but the seller had included some images and information on originals in the instructions. If I'm remembering correctly, he indicated that most were in the .60-.75 range. But included was information on one with a full inch bore.

My repro was made of machined steel, rather than the hammer welded individual rods (like the originals). It was fun to shoot, and surprisingly accurate once you got the hang of it.

Calum
 
Sorry gang, I meant to put this in the "pre-flintlock" department. DOH! :redface:

Does anyone know if .54 caliber would be "historically correct" for a handgonne? I've got a few .54 horseman's pistols and it would be nice to share ammo, as well that .54 caliber balls are reasonably affordable.

But, if no handgonnes were ever this small of caliber, I'll go with about a .62 bore.
 
The ones I made are 62 cal. because that is what
I had. I think any cal would be ok as there was
no standard at that time...
 
Earl, it would be ok to build your gonne to suit yourself and if I had .54 cal. pistols,and wanted to match the handgonne to them, I'd do it. We have two, one in .62 cal, and my wife Janet's in .50 cal. The .62 is heavily built and screams for buffalo meat with up to 100gr 2f. :shocked2: ( normal charge is 40gr.) I can't say about the .50, my wife won't let me touch it! If other people don't like your gonne, you can tell them to get their own and stuff it . There is someone on the forum who will build you a lovely one if you ask nicely. Good shooting, George. P.S. A small gonne found by the river Thames was only about .36 cal IIRC.
 
It's just a guess and medieval covers a lot of time but I would think they were rather large bore.

Probably your .54 would be on the lower end of the calibers.

Black powder wasn't very good back in those days and they seemed to make up for its low power by using large projectiles.
 
Thanks guys. I did some research and found this:
http://www.handgonne.com/gonne_2a.html

It's an original 14th century handgun that has a bore diameter of 14mm... .55 caliber. That's close enough, especially when you factor in any bore erosion that has happened in the past 600+ years.

I think I'll have someone make me one in .54 caliber. It should provide plenty of bang, I know my .54 horse pistols sure buck and boom with a stout powder charge and a 230 grain .530" ball! :D

I have a nice new book I just got today in the mail: Medieval Handgonnes by Sean McLachlan:

Well I just bought that book, due to this post, and so far the book fails to impress me due to what I believe are a few glaring errors about black powder firearms.

For example, you may have seen pictures of early hand gonnes or think of those cannon pictures where there is a large ring around the muzzle. This book emphatically states that those reinforcing rings are placed there as "that is where the combustion pressures of black powder are the greatest.

What ... :doh: ? Are you kidding me? Now I can easily comprehend where due to early manufacturing techniques that muzzles failed and perhaps burst or split there. But I contend perhaps that was due to material or barrel 'ending' (for lack of better engineering word ...) and not being supported by material 'on the other side'.

So I guess my John Bosh period correct Fusil de Boucanier, of TRS parts, in 65-cal that has a 1-5/16" thick/wide octagonal breech that tapers, then transitions to round and tapers all the way up to a 'thin' muzzle (think like a modern shotgun barrel) ... has that wickedly thin muzzle just to protect against those dangerously high combustion pressures ... the highest ones you know of the firing process ...

There's a few doozies elsewhere in the book that makes me realize that whilst one can research history ... one may actually not only miss a lot - but be completely wrong - if you aren't a shooter of firearms, but rather approach the subject from an academic point of view.

... good thing the book wasn't expensive ...
 
I finished my copy and liked the book.

I did notice that sentence as well. Sure there are some issues, but there is virtually NOTHING in print that I could find on very early handgonnes specifically.

I am now thinking about having one made based off a 14th century bronze handgonne. The original is 14mm/.55 cal, perfect for the .54 cal I am wanting. Now I just need to find a maker to reproduce it for me...

Try contacting MZL Forums member "Freekforge" as he has made and sold some on here made of steel.

Not that one couldn't make a shootable replica of bronze, but I'd sure to buy good quality bronze from a reliable mill, so one knew what they were getting. There are so many alloys of brass and bronze and some are quite brittle, as they weren't designed for barrels, but other stock/shaped items.
 
Thanks! I have seen some of his work and I believe he has made some from brass. My research shows that the proper bronze alloy should be plenty strong for the job. I will contact him as he seems like the best bet of the very few who make these type guns.
