[QUOTE="crazymonkey, post: 2880747, member: 125421"] After running ttsx bullets for awhile in my 7_08 the standard statement I've gotten is you need to come down on bullet weight with copper. The copper will retain more weight than a conventional bullet but needs more speed at impact for expansion. With the 168s you need to know what your minimum velocity is for proper expansion. My 7-08 with a 140 ttsx and a 26inch brux gets me 3060 fps and the bullet needs around 1800fps to expand. It sets my limit at around 600 yds with this setup. I didn't get much testing with the 120s just 10 rounds but they showed promising results. I was mid 3200 and just slightly bigger group I didn't finish testing as another member was looking for some 120s for his son for elk so I sent him what I had. There are some videos of the lighter bullets and what they can do to ballistics gel. [/QUOTE]
