I shoot the 140 BT's in my 7mm. Took2 deer this year with them, one at 200 yards the other at 325 yards. The impact velocities were approx. 2950 and 2700 respectively. Both shots hit bone including part of the spine, both shots exited with a .75" to 1" hole. No need to track, both were DRT. I have no complaints about their performance.

My brother also uses the BT's in his 270 (150gr version). He shot a buck at 200 yardsat the same time I shot mine at 200 (both were standing together), his bullet did not exit and was just under the hide of the off shoulder and somewhat fragmented. The deer dropped immediately. His MV is only about 2700 to 2800 fps. He likes the BT's and has taken dozens of deer with the over them years.

A friend uses basically the same load I use in his 7mm and a few years ago he harvested a cow elk at 200 yards with it. It was a complete passthru just behind the shoulder, it dropped and only kicked once, again, no complaints.

With all that said, I'm in the process of working up a load using the 160 accubonds. I think the 160 is just about the perfect weight bullet for the 7mm and will work well for most anything I will ever hunt with it. Having one all around load will make reloading much simpler and efficient.
