How would the freebore in my Weatherby Accumark 300 Win. Mag. compare to any other factory 300 Win. Mag.? Is the excess freebore found in all the Weatherby rifles or just those chambered in Weatherby Magnum cartridges?

From weatherby, their reamer dimensions include the long freebore for their own cartridges. They do not do this for other commerical rounds, with the possible exception of the 338-06 Asquare, as that has a long throat

Any round described as "long throat" has and/or a long throat or lead, and, it's a pretty cool thing when/if you are shooting barnes bullets

This type of freebore is realy the most genius thing evér created by Roy.

Corectly performed it makes any barrel(specialy with short twistrate) shoot mutch better with a mutch wider range of bullets and bullets wheight and shapes.
Feks a 223 in 8" twist performing sub inch groups with bullets from 40 to at least 75 grains.
The same is productionwise also possible in 22-250 in 10"twist

We should probably change the term from freebore to throat since it is fixed. Freebore can be anything based on seating depth.

What Roy realy did was making a long cylindric frebore followed by a long forcingcone.

What hapens is that especialy bullets with short guiding diameter leaves the not perfectly centered case, enters the freebore of close to bulletdia, thereby beeing better alighned by the bore, before entering the rifeling, This reduces tendency to "wobeling" og the bullet.
