I have experienced a little good fortune and the money is burning a hole in my pocket!

I’m looking for a big bore DGR. I have found a guy with some good price on a CZ 550 Safaris. (I’m thinking of either 375 or 416 Rigby.) I have also found a very nice Ruger #1 in 416 Rigby with dies and brass for about the same price, which tugs at special place in my hart. Any thoughts from the group about which is the best choice ?
