Supposedly Big Game will be appearing again soon.
I tried CFE223 with 120 TSX's in my present 7-08 and couldn't get anywhere near the max load listed by Hodgdon. The Hodgdon data did use 120 Ballistic Tips, not TSX's, but in general short TSX's produce less pressure than most other bullets. In fact had to use two grains less than the max Hodgdon load. Velocity and accuracy were just OK. This fits right in with mathman's suggestion of possibly sporty results with CFE223.
Luckily I still have most of a jug of Big Game it worked great, per usual.
