Any time you can get a large bore shotoing into 4" or less at 100 yards, you have a super winning combination. My groups ran around double that from the smoothbore, which I figured was pretty much the lower limit. Gil Sengle got groups with round balls from his smooth-bore 12 gauge Martini in the 3" range at 50 yards - similar to mine and plenty tight enough for big game shooting. He used undersized balls as I did, with inverted gas-check wads fro ball centering (cut from plastic trap wads).

I suspect fast twists, such as the common 35" or 36" used in modern factory rifled 12's and Hastings barrels might do better with some sort of slug, but still might shoot fine with round balls - one needs only to experiment.


Those who have slower twists may be best to stick with the round balls. I still haven't tried any of the loads I have developed for my 16 bore Husky side by side. The right tube is rifled in the slowest of twists ever cut - straight. It's 13 bore size makes for interesting looking ammo as the chamber is cut for a 16 bore hull - probably brass. Using plastic cases, the .684" ball I'm using must be glued to a wad and protrude from the case mouth. It doesn't go to the bottom of the grooves, but engraves 1/2 wad so might work. - One of these days?

Looks like good bullets and good shooting with the round balls. My 2 bore has a 1:96 twist for the round balls. A very slow twist for the 3500 grain whoppers.

I project a normal charge for that deuce bore would be in the 20 to 25 dram range. That's 546gr. to 683gr. of 1F or 2F. I don't think I'd ever want to see someone attempt that. I don't think the stock would bear it, let alone the shooter, for that matter. It is doubtful if you could hold it in both hands, waist high and fire that much powder.
: Have you shot it, bigdog & if so, what load - 10 drams?

Actually, Steve is finishing a few minor details on it this weekend. It is suppose to ship out to me on Tuesday the 21st. It will take a few days to arrive so maybe by next Saturday I will have it. I will not be shooting 500 or 550 grains of powder in it. With a 21 pound gun the recoil would be devastating. I will probably start with a light load of 175 grains and work my way up to ??? what ever I can handle. I will chronograph the loads so we will have some real 2 bore data. There isn't much out there right now to go off of.

Daryl, I think you dont have introduce you husqvarna to the audience here. believe its one of the rare M 17a with straigth rifling. have a strong interest for the swedish bore guns http://forums.nitroexpress.com/showflat.php?Cat=0&Number=109526&page=0&fpart=1&vc=1
have you make a chamber cast now, never see it from a husq with straigth rifling. would say its for 16 bore brass with roundball

That's the gun. I've not made a chamber cast, but believe it is for a brass case. That is the only way a 13 bore ball would be able to fit in a case loaded in the chamber. Using fibre wads, I hollow out the top of the uppermost one, then hot-glue a .684" ball on top. The ball sticks out the case with over 1/2 of the ball showing, but is firmly held in the plastic. I'll have to search out some brass to try. Note in the picture, the first engraved ball is a 12 bore ball I've hammered into the bore to check land/groove dimensions. The second is a .684" ball that was pushed through the bore showing the rifling engraves 1/2 way on the ball, which will hold the ball from spinning. The third ball is an as-cast .684" ball. As I noted above, I've not fired this gun yet. When I received it, my shoulder allowed no shooting at all. With time, I'll be able to shoot again as things are improving without the DR's. help. It's interesting that every time the Dr's. here are on strike, the death rate seems to fall.

yes, they were made for 50 mm long bras cases with a bore size round ball and black powder load like the upper cartridge in the pic.
when having time please make and post pics of the gun. do it come to canada with the current load of swedish classics? its a shame for swedish goverment.

Good to see you here Lancaster-

Is it possible for you to post a larger image of the page you show above here?



Daryl-

Have you looked at the CBC 'Magtech' brass?
Is it available to you in Canada?

Here's the stamping and rear sight. The front sight is a simple, normal bead. The right barrel on mine, as shown, is the rifled one. It is considerably larger in diameter than the left barrel, which is a true 16 bore and is choked full. This gun came with the 'lot' of side-by-sides that are being sold by Tradeex. I haven't checked on brass cases for it as of yet.

Very cool Daryl.
Oh how I want to put together my ball loads. I hav ethe gun in smooth 16 ga and 12.7X44R.
I want to see if a ball load is usable with the sights for close boar shot.
I will use your round ball advise.

thanks,

Re: My new GP Greener Bore Gun [Re: 88MauSporter]
      #117312 - 21/10/08 03:12 AM

88Mau - Some of the 12.7x44R are listed as rimfires. Some are listed as central-fire cases. Due to the period of make, they should all be centrefires. The picture shown by Lancaster shows a thin rim on the 12.7 cal case, consistant with centrefire cases. I think such a combination gun would be a blast and an impressive gun for shooting most of our big game! How I wish mine were just such a combination, however, with a proper sized ball (.703"), it will make a forminable bear/moose gun as it is. I am really temped to shorten the tubes, though and to install better sights. So far, I'm resisting myself. That stock will look pretty good when refinished - eh?

I have the pic only in this size but you can safe it and make it bigger. the cartridges are the 20/50 bullet cartridge, the 12,7x44R and the 9,3x57R/360BPE. the modell 17a was made in 28/50, 24/50 and 20/50, the modell 17 b was made with 12,7x44R which is allways the center fire version because the rimfire cartridge is a 12,7x42 iirc and the modell 17c was made with a 9,3x57R barrel.
I do not belief that daryls gun is a modell 17 because they allways have a pistol grip but cant say it not which model it realy is. I think that this gun deserve a good rework.

like to see a chamber cast

I see Cabalas has 16 bore Magtech brass cases. At $20.00 each, they're out of my league. I may have to turn some from scrap or make them from the .015" wall brass tubing. Tubing would be the easiest method, I think, with all parts silver soldered (low temp) together.

Twenty bucks is about right for a box of 25 from Cabela's.
There's no way they could be asking $25 a pop for those gum-wrapper cases. No one else is.
No Way.

They were listed as $20.00 and a # 1 in the quantity bracket. No where did it say if that was each or for a box of 25. I'd hope it was for a box of at least 10 but that info is missing.

Daryl-

The quantity per box (as factory packaged) is 25 pieces.
It might do you well to drop a line on Cabela's to see what the straight story is.
In retrospect, the value is good once you've run them in the gun - especially compared to the comparative cost of making your own in the machine shop.

Thanks Tinker - I'll call and see what the 'scoop' is. Even if they were to come to $100.00 for a box of them, it'd be OK.

There are some new rules about buying this sort of thing from the States now. It's something like anything to do with firearms becoming 'ordinance' and being prohibited for export - or import. I don't know if this is a US ruling, or new Canadian. I'll have to look into that as well. An FFL Licenced handgun Gun Smith here ordered something like several thousand $$ of parts from Brownells and was refused due to this new 'ordinance' law. He's been a consistant customer with Brownells for custom parts in the past.

daryl, in the name of science, dont forget to make a chamber cast and post it with land and groove diameter. the straigth rifling husqvarna is a unknown area, especialy the question if it use a 65mm or the swedisch bore gun 50 mm brass case.
