Hello. I'm wanting to buy an HS precision stock for my Remington 700 .338 RUM with the facory 26 inch barrel. I called HS precision and they told me I need the "varmint" contour because the factory .338 barrel is too big to fit in their standard Remington 700 Sporter stock. I'm also thinking a standard Remington Sendero stock might work fine (made by HS precision). Has anyone done this to their "factory" .338RUM? I don't want to end up with something with a huge gap on each side of my barrel. I really don't like the standard black plastic tupperware stock so I'm hoping for some help!
