Tail Hunter,
Thanks for the advice. I will try speeding up the lighter bullet and switch to the TTSX. Like I said in my original post I was very satisfied with the performance of the 225 TTSX I used in my .338WM. It was the 140 TSX in my Son's 7-08 that did not expand.
I normally shoot the TSX/TTSX's in larger calibers (above .338) This was our first go at using the TSX's in the smaller caliber.
HMMMM! Maybe if I am stuck on using the 140 grain bullet I will just have to go out and buy a 7mm mag or a 7mmSTW. LOL!
