OP, if you have unlimited funds, there will be no waiting. Heck, with unlimited funds you could have FN shut down a division and build your rifle. Well, maybe a week.
Thread should have been:
Unlimited funds, what production rifle would you buy?
Me? Not a clue, but my custom would be in a .338-303Br. Short gun for brush busting, some longer range shooting, and able to match a commercial .338-06 load (by my calculations anyway). Maybe on a Sako A7. Top it with a piece of Zeiss Glass, with Warne QD rings.
