Well, my sendero is neither stainless, nor a 300 SAUM. But the last time at the range, it put three 140 gr BTs into less than an inch at 200 yards. (It must be luck, because I seldom ever shoot that well)
I find that with its weight and the HS stock, it is very comfortable to shoot, for a 7mm magnum. I need to replace/rework my trigger though. It has a heavy pull, but no creep, luckily.
