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.

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??

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.
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.

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.
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)

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!
just clea your rifle with brass brush.it will be okey.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.aadhaulya wrote:As lead does not damage the rifling it cannot probable scratch the rifling.

Atul ji somebody told me that damage is due to usage of rifled slugs, what do you think about it?aadhaulya wrote: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.

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?
Though I know sabot slugs are made for rifled barrels but they are hard to get here in punjab, what can be the alternative?
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. That rifling is there to help the slug squeeze through the chokes, unlike the lead balls of yore
