To those who have used the 264 what bullets and loads have you used or favored?
Zorro: I would not be getting a Weatherby rifle, I don't think much of Weatherby's rifles though I like some of his cartridges. Common ammo is not a major concern. With gun/cartridges that one intends to shoot at long range common ammo wouldn't be used in the first place. Since you will need to find a handload that performs well or use premium quality ammo in the first place. If your using a 30-30, or such, then I can understand the common ammo arguement, since even if the ammo shoots 4 MOA that is still good enough within the 30-30 effective range [ie ~200yards].
And though I am not rich I only have two hobbies that cost much, reading and shooting, and I still have more money in my books than my guns though I own a Steyr Scout rifle. So I figure I can indulge in four or so rifles [a light rifle (ie the scout), a long range rifle (257/264/270), a medium (338), and a "heavy" (a 416)] that cost a bit more than average. The way I figure it even if I spend 3k on each of those rifles that is still less than what most people would spend on cars in a 10 year period and the rifles will last at least a couple of generations, though the small bores may need to be rebarreled a time or two.
Dave: I am not sure I understand what you mean by "scarce and expensive components"? Winchester and Remington both still offer loaded ammo so once you fired them you would have cases no problem. Not to mention you can form them from 7 Rem mag. Bullets are easy to get I would probably stick with nosler 140 partitions in the 264 except for varments.
The 270 Win, 280, or 7 Rem Mag would be better general purpose calibers, but they are not really in the same class as the 264 or 270 WBY. The 270 WBY can push a 150 grain bullet to the same speed as the 270 Win pushes a 130 grain bullet, in the 3100+ fps range with 26" barrels. While the 264 will push a 140 grain bullet to 3100+ fps [with a better SD and BC than 150 grain .270" bullets]. It is kinda like comparing the 300 Win and 7mm Rem to the 30-06...all three rounds have about the same terminal effect. But they exterior ballistics of the mags are better than the standard round.
