I have a .358STA and a .338 Baer/.375-.358STA on either side of it. The .338's kick more for the same weight bullets but have higher BC bullets to choose from. I've kill numerous elk with both the 358STA and the 375-358STA and prefer the .375-.358STA although the bullet selection when I built mine was poor at best for the 35's. When I put it up 225gr ballistic tips had just came out. My .375-358STA will shoot 250gr Sierra's 3080fps (killed a elk at 650yds with it) and 260/270gr bullets from 3000 to 3050fps. Just like motors.....there is no replacement for displacement. The same holds true with punching holes in critters. I've shot quite a few elk with my .416 Rem. as well. It's hard on them. Of the dozen or so elk shot with my .375 and .416 only one went more than about 10 feet and it was because of poor shot placement. I had a cow elk go 80 yds or so that was shot through the lungs with my .358STA.
