I have two 7mmstw's and a 7mmultramag and have owned a few 7mmremmags.I find the recoil similar to a 300winmag.In other words a little sronger than the 7mmremmag but not by a great deal.The stw and ultramag are very similar performance wise but factory loads for both are pathetically mild.In fact they are so pathetic ,that I wouldn't bother to own either if I didn't handload.Of the two cartridges ,I prefer the 7mmstw as I feel that the ultramag case is simply too large to be much benefit with 7mm bullets.It only adds 50fps to 75fps over the stw.I have taken several elk and a couple of dozen canadian whitetails plus bighorn and pronghorn with great results.I also own two 300ultramags which I use for my moose and elk hunting but if I had to hunt all game with the 7mmultramag,I would try the 140gr tsx.
