There is a very easy answer to this question. First, skip the .35 Whelen. I have never understood that one when you could have a .338 or 9.3 with a better selection of bullets. Secondly, turn your Enfield into a .338-06 because it is a great cartridge. Third, start searching for a 9.3x62 because everyone that has one will tell you how good it is and how you should have made your Enfield into a 9.3. Fourth, find a .375 because like a .30-06, every serious student of hunting rifles should always have one.
Alternatively, you could just turn your Enfield into a 9.3 or .375 and be done with it.
