I knew a loose-fitting ball from an unrifled barrel wasn't going to go anywhere near where I was aiming at that range, but I had my reputation to uphold.

The proper word for a Weatherby Magnum chamber is "freebore," a short, unrifled section ahead of the chamber that allows velocity to build before the pressure spike that occurs when the bullet is jammed into the lands and grooves.

The operator places an unrifled barrel onto the fixture and the safety door is closed.

Factory rifle barrels are bored with an unrifled area ahead of the chamber, to accommodate a wide variety of bullet weight/length configurations.

The rifle's throat (unrifled bore ahead of the chamber) can be parallel or tapered.

The bore is button rifled, which means that a "button" in the form of a very hard steel plug is forced down the unrifled bore.

For one, they require the bullet to travel through an unrifled chamber-sleeve tube before it engages the rifling, meaning it's unlikely that it will be truly concentric with the bore when it gets there.
