Looking at buying or building a 416 Rigby bolt rifle. Does it make more sense to buy a CZ550 rifle and send to AHR to have option #3 completed - or just buy a like new/used Dakota African for approximately the same price (around $4500)? Was initially looking at picking up a Ruger RSM, but these rifles truly have more appeal to me. Any other options I should look at in the same price range?

I thought once I decided on caliber (for hippo and buffalo) that the rest would be easy, but I was wrong.

Thank you for your insights.
