does anyone know of a gunsmith in canada who chambers the 470 capstick?If not what would a reamer cost for that chambering.Does anyone have any experience with the 470,is there any perforance gain over the 458 lott?

All things being equal the performance of the 470 Capstick and the 458 Lott will be similar. The Capstick might have a slight advantage but if I had a 458 Lott I would not lose any sleep over it. Sorry I can't help you with the name of a gunsmith.

good luck on the gunsmithing, my 742 remington broke 3 time,s, and fixed 3 times, by a smitty in peterborough, ont. his reply was , oh it,s a remington, my answer was NO it,s the smitty, did'nt know what he was do'n. good one's are hard to come by, and if you find one let me know. Rick, ont. canada.
