Sure would be nice to see the proof marks

Your bore measurements sound mint DO NOT ALTER THEM IN ANY WAY The invisible rifled guns' bores are tighter than rifled choke guns. I suspect your chambers were enlarged at some point in time.

This is not a problem. This is the description of "Jungle Gun". It was developed as a way to create a ball-and-shot gun while not infringing Fosberry's patent. The patent was for a gun which was rifled only in the choke, and since in Jungle Gun you have rifling which goes all the way in the barrel, there's no infringement of the patent.

Of course, if the contemporary Paradox bullet is greater than the groove (rather than bore) dia. of your gun, it would be not safe to shoot.

A ball-and-shot gun seems to be a good option for hunting big game in the brush, if most shots are under 50 yards, and the longest don't exceed 100.

Pictures had been posted on first message. More to come soon.

Hey nice gun. There is considerable difference in the rifling between the two methods with the Fosbery design having much deeper rifling at the choke and other nuances as the bullet and or shot proceeded up the barrel.

The later nitro paradoxes were capable of accuracy beyond 100yds with the Super Magnum Explora producing muzzle energy in the 375 HH range.

Holland & Holland Paradox ammo is very pricey. I tried Sellior & Bellot slug ammo loaded with a Brenneke slug in 65mm. cases in a friend's Paradox gun. They come in packs of five. And lo and behold they shot and regulated perfectly. Much, much cheaper. Not saying that they will be perfect in your gun but worth experimenting with. Lagopus.....

PM, Lagopus,

thanks, I certainly will not go beyond 100 meters with mine, nor the local conditions for boar and free range deer will allow in southern Chile. S& B are well represented here and will ask wether they have or import the Brenneke slug.

PM, a question for you. Do you think that back, say, in 1900 or 1910 all Paradox, Jungle Gun, Colindians were meant to shoot basically the same ammo - meanind, the same 1 3/4 oz conical made for 12 bore rifles, and differing only in powder loads? So that an owner could use factory ammo, and won't be limited to casting own bullets and rolling their own cartridges? And so the intended bullet's diameter for most guns of this kind should also be the same?

Btw. The records of the first public trials of Paradox quoted in Teasedale-Buckell's Experts on Guns and Shooting mention firing the gun with round ball, and reporting good accuracy. If I lay my hands on a Paradox some time, I guess a ball over 3 dram of BP would be the first load it will see.

Maybe. But because I know there were various loadings 28,30,33,36, 41 and 47 grains of cordite within just the rifled choke offerings all after 1900, I wouldn't presume all bullets for every system were .735. I would err on the side of caution, start with a .729 or .730 bullet and a light load. A good mold throwing a paradox conical and several sizers would be the ticket.

I am sorry, I would never fire modern slug ammo in a period ball and shot gun or a paradox. For the most part these are load your own type guns.
