Yeah, Straight Rifling for sure & I have been told the teem >>Hair Rifling<<, but I do not know it's true meaning nor if the method varied from straight to concentric.

I think the scattergun tubes have been lightly honed.

Indeed, there isn't a traditional mechanism to stabilize a solid projectile but the striations might have been for tossing large shot. Maybe a pattern effort on the Biks might shed some light¿

Such straight rifling is sometimes seen in muzzleloader tubes, yes those grooves can be quite fine, and Germans have the term "Haarzüge"
I have read the idea that those straight grooves might help in reloading a badly fouled barrel. But I think nobody knows for sure what the purpose , or the hoped-for effect really was.
Remember, 1914 was not that for from muzzleloading times and superstitious recipes to improve the "Brand" or the killing properties of a barrel.
in fact such superstition is around even today, you still come across claims that a barrel "will not kill properly".

Yeah, maybe the technology / concept bled over in an attempt to assist a Lad or Lady in their quest for game and aide in the pattern just in case they had the barrel pointed in close proximity?

Maybe the maker didn't expect the custodian to clean it? Because apparently someone didn't do a lot of cleaning......

Ah, „Haarzüge“ or something akin to Micro-Grooving or designed striations......

Dietrich on >>Straight Rifling<<

I guess the best text is:

...>>The theory behind the straight rifling goes like this: When the shot and wad column is accelerated down a smooth bore, it is free to get some uncontrolled spin as for instance by the Coriolis force, the force that makes tornadoes twist. This spin would cause centrifugal dispersion of the shot after leaving the muzzle. By guiding the shot and wad like this spin is avoided, this improving shot patterns.....,,<<

There is a possible reason for the scratches in the shot barrels that has not been extensively discussed (argued about?), and that is a hundred years of use with black powder with subsequent cleaning, using various grades of abrasives that may not have been suitable for cleaning barrels. The breech face shows signs of heavy black powder use over many years. There was an earlier comment suggesting that the nitro proof of the rifle barrel indicates the shot barrel attached to it may have also been nitro proofed. The barrels would have been separately proofed according to the ammo intended and each barrel would carry its own proofmarks. The firing pin bush evident on the breech face is not original to the gun. The original "hound's tooth" firing pin was likely replaced with a "gas proof" Mann Niedner type, and likely during the conversion to 222 Remington. The signs of black powder use illustrate my well known, but admittedly prejudiced aversion to using black powder in my antique guns. My opinion concerning the bushed firing pin is based on a similar conversion of my Sauer BF in 9.3x72R Sauer & Sohn. I believe if the barrels had straight rifling to use .577 Snider (Snyder), or other rifle, ammo, they would have required proofing as a rifle. As always, I may be entirely wrong.
Raimey,
If you want to try .577 and need rifle cases let me know.

Ford:

I think the only thing original to the platform are the Striations...... Now that Snyder would make a Lovely Boom on the 4th, but I have a subpoena this week for Court so I don't think I could get by there by then. But I will certainly take a rain-check...

Better yet Ford, I'll just bring the weapon down to your way on the 4th & we'll set it of there......

You do keep a First - Aide Kit in the Truck, don't you??
