I just called Del-Ton, since it's been months.
They're still working on orders from NOVEMBER. The gentleman on the phone said they're just now hitting the end of November's orders, and will be getting into December's in a bit.
My ETA? "About 8 weeks, maybe more."
Looks like the majority of my rifle shooting this season will be with the Mauser, after all.
As a sidenote - I took another newbie friend to the range recently. Look for a full write-up soon.
