Straight rifling
      #226519 - 07/03/13 02:03 AM

I am in need of advise. I am looking at a 10 bore Jones underlever with damascus barrels, that has straight rifling in both sides, by Smith in England. No rifle sights. Now, is this built for shot, or ball and shot? What is the idea behind the straight rifling? If there were a twist to this, I would jump on it, but am kinda puzzled! I have today and tomorrow to decide, so any responses would be appreciated!
Thanks, Doug

Doug look at the muzzle end of the rifling very carefully. I had a Greener that was straight almost invisible rifling up to the last 8 inches and then it started a twist. I owned it for 6 months before I noticed the twist.

Doug - look closely as Casper indicates, but if they are straight rifled all the way, they'll still shoot better with shot and round ball than a totally smooth bore, however the rifling might pick up some lead now and then. The wads won't spin to open shot loads, and the ball will be prevented from spinning and taking off like a curve ball as well, thus better accuracy potential.

I have a straight rifled SXS Husky that is smooth choked modified left barrel and straight rifled 13 bore on the right. It shoots beautiful cylinder patterns with the right and of course, very tightly with the left.
The right shoots into about 2 1/2" on average at 30yards with black powder and round balls.

These straight rifled (Husky's)were developed by Husqvarna to beat the 'rifles only' law for moose law in Sweden back at the turn of the century. That they would also shootshot well for birds, was the intent. Mine was built in '98 or '99.

Well, the rifling is indeed dead straight. Wall thickness at the muzzles is .045, and there appears to be a slight choke. Starting to look like a ball and shot setup to me. Still considering! All input is sure appreciated!
Thanks!! Doug

Straight won't do anything for ball.

That's what I wanted to know! So- guess maybe it's for fouling control? Thanks, all for the response. I think this is not what I have in mind after all, so will continue looking.
Thanks, Doug

I think that's the one down in Texas??? I had it here last summer.If so there is a deep scratch/scar in the LH chamber. I passed on it. Too bad because it is in lovely shape for such an old piece.

When I had it here Omnivourious Bob stopped by to look it over with me. He said that the straight rifling was to allow the black powder crud to build up the the grooves w/o slowing down the shooting for cleaning.
That's the first one like that I'd ever seen. I still don't know what to call that hindge arraingement? Possible crab claw?

edit: The lack of any English proof marks was another concern. The only markings I remember seeing was "Smith, London"

You're right, AkMile - the grooves also help with a fouling deposit area, however they also allow blowby of powder gasses, which allows gas cutting of wads, balls (unless patched) or shot.

Straight rifling has actually been cut into bores since the 16th century - it is not something new to the late 19th century.

Over the years, straight rifling has been used for different reasons.

The reason I mentioned above is as valid as any other - it allowed a shotgun (preferred by Swede farmers) to legally shoot moose, yet they still only needed one gun which was mostly used with shot. One merely carried a couple round ball loads and if a moose presented itself, bang!

If slightly choked as well, the patterns would be improved over cylinder boring, of course, without further injuring ball shooting. They were close range guns with ball - ie; 75 to 80yards. That can also be handled easily with smooth bores and round balls with good load development, but smooth bores had been declared illegal - hence straight rifling.

If I wanted to shoot and hunt with round ball, I would not purchase a rifle without more normal twisted rifling.

At some point, the round ball, from straight rifling, or smooth bore, takes on a spin and careens off to one side, down, and never in the same direction shot to shot. A normally loaded smoothbore with loose ball, induces spin while inside the bore, which limits it's accuracy range to even less than 50yards. Given a good charge, the straight rifling will deliver the ball as a knuckle ball, non spinning, which will happen, given enough time of flight.

However, if one calls his the moose to his blind, 20 yard shots are the norm. and either will work just fine.

Many years ago, my brother shot a nice big dry cow moose (no calf), making a perfect lung shot at 95 to 100yards distance. Using a Brown Bess Flintlock Musket, the cloth patched 600gr. pure lead ball flew true to the mark dropping the cow in 4 steps. The ball was perfectly expanded to over an inch in diameter against the off-side hide. I still have that ball - somewhere?

They'll work at close range - properly loaded- straight rifled or smooth.
