Got a very shot out bubba Lee Enfield, a 1916 No1Mk3, that is in desperate need of a barrel. I've also got a spare .358" blank. Any recommendations for a chambering that would fit the magazine, feed well, and be roughly within what the action can handle? Current leaders are 35 Whelen x57R, 350 Rem Mag, and 35-303, but I'm open to suggestions for something ideally more readily available
