Steelhead's got a point. The 1917's aren't cost effective anymore given that you can buy off the shelf CZ550 actions for the 416 Rigby for about what you'd pay a gunsmith to do the conversion work on a 1917.
That said, I wouldn't mind have a 9.3x62 on a Remington Model 30. I've got one in 30 Remington that is too nice to cut up but I'm keeping my eyes peeled for a clean donor.
The 1917 has one of the best bolt action safeties ever made, in my opinion.
