Not to start an argument here but meerly want to add some input on this. We all here this all the time, that the WSM's do not have enough powder capasity for the heavier bullets like the 300 Win mag does. While this may be true, if a person needs more bullet weight than a premium 180 grain bullet to cleanly kill any animal that one would be hunting with any 300 mag that person needs to step up to a 338, 35, or 375. A 180 grain nosler partition, Barnes, TBBC, or any of the other premium bullets will kill any animal this continent offers us to hunt and do it with authority.
