I saw .257 WTHBY post on this site the other day and it rekindled my .257 Roy interests. The cartridge itself is a handsome one, looks like an ICBM. I have always wanted one but end up talking my self out of it. The arguments always end with, I already have a .270 Win., why do I need a .257 WYHBY. Below is from the Nosler #7 manual.
.270 Win 100 gr .257 WTHBY 100 gr
3550 fps 3576 fps
110 gr / 120 gr
3503 fps 3402 fps
Heavy guns, expensive brass, more powder burned, long barrel, hard to find ammo. Heck... I still want one.
