[QUOTE="Varminator 911, post: 206873, member: 9705"] [b]Throat for long bullets[/b] The new Al tipped and some other bullets are pretty long. Even longer than the 300SMK. Of course it's not just the bullet lenght/COL but the bearing surface that is outside the case that is of concern. So I'm thinking that the throat might have to have a little freebore if one is both going to get the right distance from the lands for accuracy while still keeping as much of the bullet out of the case as is appropriate. In this regard, the Weatherbys are famous for their freebore. Does anyone know how much the freebore is? If one bought a 338/378 Weatherby would that amount of freebore be about right for a really long bullet to be near the lands? The bearing surface on the 280gn Al is about 0.7 inches long as well as I can measure. So if 0.3 were in the neck, that would leave about 0.4 inches outside. Is that more than a typical 300SMK setup? Thank you! [/QUOTE]
