Brother shot a 250 lb buck in Missouri this year. 165g ttsx. You never know what a bullet of any make will do.

300 WSM, 165@ 3150.

Bullet hit the shoulder, angled up the spine, and was under the hide just behind the skull. Buck was laying in it's tracks of course which is all that counts for us.

We found the 6.5 ttsx one of the very easiest of all tripple shocks to tune in three different calibers. 6.5x47L, 6.5 Creed, 6.5 Sweed with R#26 and fed 215 is unreal accurate and fast. I formed brass out of Rem 22/250 for the 6.5x47L so we could use the 215 which the #26 likes.
