I load for two brothers and one likes the 130TTSX and the other likes the 140TSX. They both have killed elk with their respected 270 load. Splitting hairs really. I think which ever you can have the best group with is the one I would lean towards.
Like everyone else said whichever shoots best as long as it is a well constructed bullet. My brother personall shoots 130's out of his and has put a lot of elk to sleep with it. O'Connor who is well known for his love for the .270 used the old 130gr. winchester silvertip (not balistic tip) ammo on many an elk hunt. The 130's shoot as flat as a frozen rope if you are a MPBR guy rather than a balistic plex or turret spinner.
whether 150 or 130 get a good bullet, tsx (any variety), accubond, partition, a-frame, etc
Have you thought about a trip out west for big game? Have you dreamed about what it might be like to ride horseback through the beautiful Rocky Mountains, while looking for deer or elk? Have you dreamed maybe of traveling to Canada for a moose, elk, bear or deer hunt? Have you wondered what it might be like to see the wild Alaskan bush?
Well, I have a little advice for those who have wondered those, or similar thoughts. JUST DO IT!! If you think you might enjoy it, my bet is that you...
