GameKings aren't my first choice by any means. (I don't even like them over Hornadys in my hunting rifles as simple accuracy goes overall.) I haven't hed any complaints with them however on several moose I've killed with them. In fact, a 250 .338 was one among the few (three) instant tip-overs I've had when killing moose. And none of them was a CNS shot. (I've also driven that same bullet through the meaty shoulder area of a longer distance moose.)
But I suspect Sierra won't worry about how good or bad their bullets compare to others as long as people keep shooting 50 of theirs for every 5 of the bonded, mono, or other premium construction bullets that get shot. It's a simple fact, if everyone made only Partitions (or TSXs), not everyone would stay in business. I'm sure Sierra adequately maintains their market share doing what they do.
