Can anyone with one of the WSM detachable mag rifles tell me what the max OAL that they will support is? I know the SA blind mags will let you get pretty close to 3", are the detachable mags the same? I'm looking to build a 7WSM for long range hunting using the Berger 180VLDs but if I can't load them fairly long it kinda defeats the purpose.

Also is the new Trophy Hunter WSM built on a large or small shank action?
