I am looking at either the CZ 452 or 453 Varmint in .17hmr. At my local Walmart, they did not have either one of the varmints in the special order catalog. Online, Walmart has the 452 Varmint listed, but it is not in .17hmr. Is there any way that Walmart can still order the model that I want although it is not shown online or in their store catalog?
