I shot my last elk with my 300wsm, 165gr TTSX, I got him but he didnt go down like my elk last year with 180gr TSX, now Ive got a 180gr TTSX load for my 300wsm's and my blaser 300 Win Mag, I really think there isnt a better round for the 30 caliber say 0-600 yards, past that the bergers give you better flight but for me I like shooting no further than 400 yards but can out to 600 with confidence. My buddy shot his elk with federal Premium 180gr TSX with his winchester 3006, dead elk, one shot 334 yards, complete pass thru.
