I'll be packing my 270WSM and build a great110gr TTSX load that's shooting cloverleaf groups at 3530fps. This would give me a steady hold out to 400 yard and a 10" drop at 450, still traveling at 2650fps. I know I'll get the " you need a heavier round" comment but I'll have sidearm as well. This 110 TTSX load is right in line with a 25-06 and 257, both very popular sheep rounds. I've considered wind but I rarely shoot beyond 300 yards. I have spoken with people who have taken elk, hogs, and deer at 500+ with this round and I feel very confident in it's abilities. Any thoughts or advice?
