Looking to start a project to build a 404 jeffery.

Don't really have any plans on going to Africa anytime soon but shouldn't everyone have a big boomer in the safe?

I already have a lead on a model 70 in 300 rum for the action.

Im looking for suggestions on barrel length and maker...ss or cm?
Type of wood for stock? Recoil pad?
Type/manufacturer of iron sights?
bottom metal?
Gunsmith?

any and all suggestions greatly appreciated.

Thanks in advance.
