The 257Wby is one of the most versatile cartridges if Big Heavy Dangerous game are left out of the mix. Even though the 257Wby has killed everything from Cape buffalo to Grizzly bear which is not the best choice of cartridge on these animals. Now the 100gr TSX and the TTSX along with other premium bullets have made the 257Wby very versatile if you are considering every thing but heavy dangerous game. But make no mistake, with these monolithic bullets the 257Wby can and has dropped dangerous game in their tracks.
One thing for sure there is no factory production cartridge that shoots flatter than the 257Wby mag. So if I am talking about most hunting except for Big Dangerous game I say the 257Wby is one of the most versatile. Having hunted Big Dangerous game I would say the 257wby using premium bullets like the TSX, I would not be afraid of dangerous game being in the area where I was hunting lesser game.
When you consider that my 100gr TTSX load is well over 3000fps at 200yds which is the limit for over 90% of hunters and the distance they take most game they shoot, then the results when using a 257Wby are simply phenomenal when game is dispatched. The monolithic bullet has elevated the 257Wby to even higher highs than it already occupies. It allows for close shots at these velocities without fear of the bullet coming apart and has enough velocity for these to open up at long range.
When I am moving the TSX or TTSX at 3624fps out of my Mark V 257Wby, it becomes even more versatile and at a greater level than Roy imagined. I don't think any one of my friends who use the 257Wby for years could have visualized the 257Wby being raised to a higher level than it had already obtained, but the TSX and TTSX have added to it's already fantastic potential. There was a reason Roy liked it the best of all his cartridges even over the 270Wby which was his first and the 300wby that is so popular.
I have dropped Elk, Black Bear, Mule Deer, Whitetail deer, Russian Boar, and Coyote with the 257Wby and fixing to own my third 257Wby, the previous two, a Vanguard and a Mark V Synthetic. It truly stands alone in the quarter bore and makes it's self a contender even among the bigger bores.
