Re: 12 gauge Double Rifle.
What is the difference between a 12 g rifle and shot gun?? Except maybe the rifling in the barrel. It should be able to shoot regular shot gun cartridges I suppose.

Re: 12 gauge Double Rifle.
The double rifle is very heavy built as it has to withstand very heavy recoil as heavy grain ammo is used and some type of special setup is done while setting up the barrels for accuracy(i dont know much about it).aadhaulya wrote:What is the difference between a 12 g rifle and shot gun??

And yes it can shoot regular shotgun cartridges but its of no use as their will be very wide pattern with less range and impact, in smooth bore the wad carries the shots upto the end of the barrel but in rifled barrel wad is punctured very soon. It also destroys the rifling.

Not.The pattern will be wide because the rifling spins the shot, with diminished density in the center of the pattern. Velocity and impact are not affected.
Leads shot CANNOT damage rifling, but will cause leading, thus affecting accuracy.

Yes the rifling spins the shots to a directional tangential to the rotational motion of the shots. I dont know much about velocity and impact i assumed that it will decrease.
Lead cannot damage the rifling as barrels are made of much harder metal than lead, but any type of built up or scratches adversely affect the rifling.

Re: 12 gauge Double Rifle.
As lead does not damage the rifling it cannot probable scratch the rifling. But lead build up can affect accuracy, but only till the build up is cleaned up. And this clean up is required at regular intervals, for normal guns using proper ammo also. That is my understanding and that is what I practice for all my firearms and airguns.Sukhraj Singh Pannu wrote: Lead cannot damage the rifling as barrels are made of much harder metal than lead, but any type of built up or scratches adversely affect the rifling.

Right sir but I witnessed these kind of scratches after i fired a shotshell through this rifle but that can be due to age of the weapon.aadhaulya wrote:As lead does not damage the rifling it cannot probable scratch the rifling.

12 g ammo including slug shots are made of lead, at least in India. The rifling is more likely to scratch with a proper cartridge specified for the bore of the weapon. As the rifle bullets are metal jacketed (I think most of them)

Yes that lead shots used in IOF ammo did that!aadhaulya wrote:Sukhraj Singh Pannu wrote: Right sir but I witnessed these kind of scratches after i fired a shotshell through this rifle but that can be due to age of the weapon.

I don't think a lead bullet can cause a permanent damage to the rifling, more than a metal jacketed bullet.Sukhraj Singh Pannu wrote: Yes that lead shots used in IOF ammo did that!
But the senior experts would be able to clarify the point better, as I may be wrong.

Though I know sabot slugs are made for rifled barrels but they are hard to get here in punjab, what can be the alternative?

Re: 12 gauge Double Rifle.
I use 'Shaktiman rifle slugs and these are rifled slugs, meant to be used in smooth bore shot gun. The purpose of the rifled slug is to give it some spin for accuracy from a smooth bore.Sukhraj Singh Pannu wrote:Atul ji somebody told me that damage is due to usage of rifled slugs, what do you think about it?

If a lead slug can cause damage to the rifling in the barrel, just imagine what a disaster would the recommended ammo (which would be metal jacketed), cause to the rifling and barrel.

Re: 12 gauge Double Rifle.
I dont think the 'rifling' in a rifled slug imparts any noticeable spin at all. That rifling is there to help the slug squeeze through the chokes, unlike the lead balls of yore

Re: 12 gauge Double Rifle.
I am sure that the rifled slug will not provide adequate spin in a smooth bore barrel. But in my DBBL the slug doesn't have to squeeze out, as it easily slips through the choke barrel. May be some chokes are tighter then the regular choke barrel of an Indian DBBL gun.Safarigent wrote:I dont think the 'rifling' in a rifled slug imparts any noticeable spin at all.

I suppose some experts will be able to throw some light on it.
Although, I respect your opinion, being a hunter, a status of being something, a lot of us would like to achieve.
