300 WM Dangerous game calibre rebarrel (Advice Welcome!)

[375Ruger416]

Given the action length and the fact that you reload, I would go with a 458 win mag or 416 Taylor.

Should just need a new barrel and should feed well. Highest chance of success with the lowest cost and inconvenience. Two great cartridges IMO.

416 Ruger, or go really cool and do a 500 A Square, or even better, 550 Express
