RE: Shockwaves in a encore
I used them last year - took a real nice 6X6 bull elk opening morning. The bullet, at about 70 yards, entered the ribs on the right side and wound up in the shoulder on the left side. I found the jacket and core in the same spot, even though they had separated. Even found the little yellow plastic tip.
The 250's shoot a little better in my guns and, based on one animal harvested so far, seem to have adequate penetration. For deer, though, I would used the 250's or even the 200's - depending on what my gun liked the best.
