Redhawk,
My 7 mag loves them (.25" groups at 100 yards). BUT, They do not perform consistently at high velocities close in. Two examples.....
1. 160 lb. 8 pt.- shot in the shoulder at 35 yards. Never took another step, but bullet penetration was less than 4" and turned to scrapnel. Velocity was 3,150 fps.
2. 165 lb. 8 point- shot through both lungs at 25 yards. Only went 25 yards, but small entrance and exit holes, not much blood.
So they did indeed kill, but bullet performance was not quite what I expected. So now I use the 140 grain BT in my 7 mag which is set up as a "bean field rifle" for use out of shooting houses. Generally, I won't see a shot of less than 100 yards in this situation and the BT performs great.
In my 7-08, which I use for woods hunting, I prefer the sierra pro hunter. I am also working with some other rounds as well, but no BT.
Good Shooting,
Smoky
