[Choosing the ammo..]

Does it make any damage to my barrel or not?

[Choosing the ammo..]

And if it is possible, please suggest me the alternative names of these ammos.

[Choosing the ammo..]

I would like to ask that, can i use standart ammo (exept sabots) in a fully rifled barrel?

Like rifled slugs..

Is it possible to use them?

Does it make any problems?

I have a Nova rifled slug.

Thanks.
