Its a good point, maybe I can find one with a shot out barrel, though it seems guys don't shoot the big bores much, mostly safe queens. (not mine, I shoot em all!) I can order a CZ in 404, A guy close to me (Dealer) has one in stock, looks like nice wood to:

CZ 550 "Safari Classic" Gloss.404 Jeffery In stock$2899

What would be the cost for the average custom build?

I've never had a custom before, so feel free to chime in, he's my guesstimate:

Brno ZKK 602 - $795
Custom Stock - $2000 (Something like Luxus Walnut)

Custom Barrel - ???
Reblue - ???
Bolt Face open up and action job: ???
Whatever else needs done: ???

Plus put it all together, final fit and finish, I'm guessing I'd be well over what the CZ is. No peep sight though
