Freebore excess in Weatherby rifles chambered in non-Weatherby rounds?

[Yorkplates]

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?

[Hired Gun]

Only the real Weatherby calibers have the extra freebore as part of their spec. All chambers in Weatherby rifles are cut to industry standards.

Hired gun is right , I've seen a couple Weatherby's that were chambered for standard rounds and their throats were cut normal length.
Part of weatherby mags get their extra velocity is from the freebore , the bullet is almost free from the case before it hits any resistance.

Those deep freebore WBY Calibered rifles can't shoot those boat tail bullets by Serria either. They make a group 12" at 200 yds. They have to shoot the flat base bullets. Serria told me that.

Interesting. Thanks! My choice in 300 Win Mag pleases me more knowing that.

Freebored Wbys will shoot match boattailed bullets into 8 inch five shot groups at 1,200 yds, all day long.

My 300 Wby Accumark has approximately .425 inch freebore and shoots sub-MOA out to 400 yards. It likes 200 grain SMK which are boattail. Beyond that I need more practice before I can say for sure.
