Last week we tested Sig-Sauer .357mag 125gr V-Crown from a revolver. Perhaps unsurprisingly, it did not do well. V-Crown has a history of failing to expand when fired through heavy clothing and even at .357 mag velocity it still failed. But one of the really cool things about .357 mag carbines is that they squeeze a lot of additional velocity out of the cartridge and can make something really special out of an otherwise mediocre load.
To be clear, this isn’t always the case. A light charge of fast burning powder won’t net much velocity gain from the longer barrel. A bullet that is too fragile will fragment at higher speeds and fail to penetrate adequately. But with many loads, that extra barrel length can make itThis post was originally published on this site
