Re: Considering .300 Wby without freebore
I have had and still do have several 300 Weatherby rifles mostly for 1000 yard match shooting.
Most free bore rifles such as the factory Weatherby 300s are not very accurate at all.
You change the velocity that's lost from eliminating free bore, by going to a few more inches of barrel length. That is the equalizer plus you will have much better accuracy then the factory chambering that has free bore. With freebore your "jumping" the bullet into the lands and that is where you lose accuracy. Most rifles fire much better when the bullets are NO MORE then .055" off the lands. A soft touch into the lands seems to work very nicly.
With the standard factory Weatherby, it sometimes seems like you can't get the bullet closer then 2 feet from the rifling. Just some humor here on that last statement.
Freebore and excessive velocity== poor accuracy.
