are the guns simply noted as "allocated" on the davidson's website??
if so that usually means that they've bought a small number and are or have already doled them out to their "preferred dealer"(or whatever they call them) shops. last time i went looking over at the davidson's site, many of the "interesting" or odball configs. or chamberings in various guns were noted as "allocated"
so if you WANT a .350 Rem Mag M-77 you might want to talk to your dealer and see what they have to say. they just MIGHT be one of the lucky shps that get one (or know who did).
NOW if instead it says they've been allocated for a specific dealer or similar. then, of course, that's different.
