The straight rifling and Karl Pirko's percussion over-under double rifle

[@dangvorbei5304]

Great demonstration of what happens to shot spun out of a spiral-rifled bore. If you ever pattern snakeshot out of a normal pistol, you get a donut-shaped result with a big blank spot in the middle due to centrifugal force making the shot go all wonky. But not with straight rifling.

[@SwampyMusic]

Nor with smooth bore. I have a Remington 511 X (If I remember correctly), a rare smooth bore bolt action single shot .22. What you explained in my experience with rifled 22's-vs-the smooth bore is exactly true. I also get more range with the smooth bore. Of course I am referring to .22 "shot shells", often referred to as "rat/snake rounds".

[@dangvorbei5304]

@@SwampyMusic Henry now makes a "garden gun" just for .22 shot shells. It's a fantastic concept, and winds up being one of the most truly practical guns out there.

I shoot 1/2 oz of #6 shot in a 44mag 94 marlin, and I get about 6" pattern within 10-12'. Within the usable range, it's a uniform pattern. The problem is that the usable range is really short. Compare that to an equivalent 1/2oz 410 load in a cylinder bore.

First, that rifle is superb, double rifles (or as we call them in French "express") are always a treat. Second, the purpose of that straight rifling reminds me of the "paradox rifling", patented by col. Fosberry (yes, the same Fosberry behind the self cocking revolver sold by webley). A showdown between the two would be interesting in the future. Anyhow, great video as always on this channel !

Double-barrelled rifles are mostly used by reindeer-hunters in Norway today. You are to have allowed to have one cartridge in each barrel while using a double-barrelled rifle while hunting reindeer, but in a single-barrel you are only allowed one cartridge (none in the magazine).

[@prjndigo]

ball ammunition in a smoothbore can end up rolling, this is actually rather common in bb guns (even in the rifled ones) and having rifling inside the barrel actually helps in swaging the balls into a not-ball state

You should try it with bird shot. I made an American longrifle with straight rifling and found that bird shot kept a tighter group than just a cylinder smooth bore. Maybe it was luck, but I'd like to see another firearm with straight rifling try it and see if you get the same results.

Morning coffee and capandball ☕❤

[@Cletrac305]

Great video as always! Oddly, I had an idea before I knew that they were made that straight rifling would be better than a smooth bore because of the possibility of a round ball obtaining a forwards or backwards spin or "roll" just like with a baseball a rolling ball flying through the air will always be pushed up if rolling backwards or down if rolling forwards. Straight rifling would prevent this. When you talked about gasses escaping unevenly it seemed to be another mechanism for this to happen. Flame blowby marks on straight walled cases are usually very much longer on the top side when fired because the bottom is lying against the chamber. This could roll a loose ball.

[@DavidHarris-qn7em]

Straight rifling locks a bullet in a stable configuration..allowing more pressure to build up without much loss due to bypass gases

[@bobperrine6193]

Thank you for another great video. I learn something new with everyone .

[@wildcatindustries8030]

If I’m not mistaken the Taurus Circuit Judge 45/.410 rifle/shotgun had a rifles barrel which would negatively effect the .410s shot, however they did make a straight rifling adapter to thread in like a choke to help stop the spin and correct the flight path of the shot from a circular pattern to more of a traditional smooth bore pattern.

I have handled a few flintlock rifles dating from late 1700,s to early 1800,s in South Africa that have straight rifling, this Straight rifling makes a lot of sense because they would have been using these guns to hunt and defend from dangerous animals and it is well know that multiple projectiles were used when being attacked by hostile tribes.

I had a Pirko made Lorenz extra corps carbine. It was capable of hole-in-hole accuracy at 50 yards but boy was that muzzle TIGHT, I have to believe much tighter than ordnance regulation. I had to use a ball starter to load it even sizing the compression bullet down to .540.

[@krockpotbroccoli65]

Interesting firearm. The straight rifling is probably a bit of a non sequitur, IMO. Any advantages you get over a smoothbore are kinda mooted. While you are able to shoot both shot and patched ball with reasonable efficiency, you lose the speed loading of paper cartridges in a smoothbore and you also lose some performance with shot. I dont really see the point of it. Id rather just have rifled on top, smooth on the bottom. Like more contemporary combo guns.

Perhaps if I take the barrels off, there are markings under the wood front gard, which is one and the same with stock. The barrels also have some kind of protective, Damascus like finish.

Many of the original ball firing rifles had nearly straight rifling of 1 turn in 5.5 to 10 feet. This imparts enough spin to assist the spherical projectile, and marginally stabilize others. With a conical modern bullet it's ineffective. Small slugs at best, balls even better. This would be in the pre-cartridge era, muzzle loaders.

I was told two reasons for straight rifling. The first was for German or Swedish hunting laws. You were only allowed one rifle, so having a straight rifled shotgun barrel kept birdshot tight before chokes were commonplace. The second barrel was for slugs or minet balls. The second reason was that the channels were employed as crud collectors, so blackpowder fouling would be kept to a minimum on the bore surface, and more shots could be taken between cleaning breaks. Increases rate of fire, if you will, but minimal effect on accuracy, hence the second rifled barrel.

I must say, I'm very uncomfortable w/ this. These are well known to be extremely dangerous, w/ countless reports of injuries & even fatalities. In every case, it appears to be the same recurring issue, where anything downrange that happened to be inline w/ the barrel would end up being destroyed in the event of operator induced discharge, invariably involving the manual depression of one or both triggers. As a 2A activist & firearms enthusiast, it pains me to admit that this is exactly the type of device that has no business in civilian hands!
