I have 145 gr Winchester Silvertips, which is the only Silvertip option available on the cheaperthandirt web site. Does Winchester not make a 125 gr Silvertip (which I'd very much like to have for my SP101)?
Tyro, they do make a 125 silvertip @945FPS for ~248FPE. They also offer it in 110Gr. Recently, I stumbled on a bunch of discontinued Silvertip 90Gr. (.38 specials).
I'll assume the caliber in question is .357 Magnum. AFAIK, Winchester doesn't offer a 125gr. Silvertip in that caliber. They do have a .38 Spl. +P 125gr. Silvertip.
