I have seen a number of european guns with straight rifled barrels. They are typically smaller guage guns. What was the purpose of having straight rifling?
I currently have a 16ga Husky rolling block in my possesion with a 36" barrel with rifle sights and ...you guessed it...straight rifling.
Thanks
Tom

Tom most guns with what appears to be straight rifling isn't. Most have a very slight twist starting in the last 6 - 9 inches or so. This was to start the lead ball out slow and then put the spin on it so as not to have pressure push the ball so fast that it strips the rifling. I had a 12 bore double rifle like this. The last 9 inches had a very slight twist the rest was straight.

Thanks Mike.
I looked at it when it came in and I thought that there was someting odd going on. That twist is slight enough to be non-existant. Still looks interesting though
Have to slug it and see what can be done.
So, how well did your 12 shoot?

Could this be gain twist? Or maybe a 1 in 100" or something? I'm curious. I would like to own and experiment with one of those guns. Too bad I'm broke. Guess I will have to buy a lotto ticket. CCCB

I never fired it. I bought it as a wreck/project. Someone saw it and wanted it a lot more than I wanted to mess with it.

No gain twist here. And if it actually has any twist at all it's when I cock my head a bit to one side.
Either way, just ordered up some brass cases and two molds; one for patched and a full bore ball.
Too cold to shoot but plenty of time to cast.

The straight rifling was an economical way to circumvent the Swedish game laws that put a ban on hunting moose with smoothbores; you had a "rifled" bore for the moose hunt, but you could still load the gun with shot and go birdhunting without destroying the shotpattern, as a true(spiral)rifled bore would have done...
Straight rifled guns were made from both percussion muzzleloaders and breechloaders, although I cannot state exactly when these game laws came into effect....
I personally own a Husqvarna M1860 (popularly named "Wrede's rifle", after the inventor) that was originally approx. .47 cal., then sporterized and reamed out to smoothbore; it is now approx. .52 cal. straight rifled.

Waco, thank you.
Now that makes a great deal of sense. The bore was originally .660 and when it was rifled it was opened to .690 or so. I did fire it with patched ball and have loads with a full size ball but haven't tried them as of yet. Really a tremendous amount of power over 150gr of black with the almost 12 ga ball. If I can get to to group into 2" at 50 yds I'll be happy.
I think that it's feasible.
Now just have to take it out for pheasants in the fall...
