The great Swift fell like the 264 wm. Bad advertising and talk by supposedly knowledgeable writers and manufacturers ammo and twist rates to make a supposed barrel burner. But very few people have ever changed a barrel.
I still hear people today who are just hunters say oh that barrel wont last long. I say it will last longer than you will as you shoot 10rds a year. lol
Great rounds still today.
You're correct'..., as well as Remington who made a special bullet they wouldn't sell to hand loaders to get the muzzle velocity's they claimed at the time, today we know, this type of bullet as a swap shape or double running band, as a bearing surface with the bullet, actually quite smart at the time. But yes the gun writers beat the old .264 Win Mag up pretty hard, as did they'.., the 6.5 Rem Magnum one heck of a 6.5mm, but in their defense bullets weren't where they are today. As a big game hunting rifle/caliber used then put back in the safe after the season, the .264 Win Mag will last a lifetime perhaps two lifetimes.
