I currently have a bubba 1917 Enfield that I am looking to make into something new. I have contemplated the gamut of cartridges available for this beefy action and lean toward the big bores like .495 A-Square, 500 Jeffery and .577 T-Rex. I work in close proximity with coastal brown bears so these cartridges would not be totally wasted and relegated to the shooting range. But, since I am working on a .458 Lott already I am thinking of going with something a little more middle of the road. Strong contenders are 35 Whelen, 416 Taylor and 9.3x62mm Mauser.
What are others thoughts on this project? They all seem to have pros and cons and would be interested in others opinions.
