A Barnes TTSX in 120grs will out penetrate most 140-150gr bullets, you can start it faster, and it will recoil less. I have been loading 120gr X, TSX and now TTSX bullets in and for my dads 7 Mag, my sons 7 Mag, my BIL's 7mag and my associate pastors 7Mag. This bullet has accounted ittself very well on game up to medium sized African animals, Elk and Black bear. Powder was a hefty dose of Reloader 22.
That bullet for those rifles has been working wonderfully for about 20 years or a bit more. You can get them to launch at around 3400-3500fps, and this makes them VERY deadly as well as easy to hit with out to 500 yards or so IME. IS my/our one load for many 7mm Remington Magnums.
I am going to play with this bullet some more in my 7mm Mashburn Super, (at 3700-3800fps)but because I have the powder capacity to drive them fast enough to suit me (over 3400fps for sure) I will also be testing the 139GMX, 140TTSX, and 140 Accubond in this rifle.
