While I haven't used them in a 358 Win I have used them successfully in a .350 Rem mag. A number of Deer and one black bear fell to this bullet and I see no reason to change. I also use there 250 grain in my .35 Whelen. They hit with authority and just plain work. I've never had an issue with their accuracy either. My 350 mag is a Remington 673 and my Whelen is a '95 Winchester. I also, have a 35 Remington in a 336SC, I've never tried the 220's in it, preferring to stick with 200gr as I really don't think I case capacity would give me the velocities to make the bullet work as well as a 200 ,and ,I don't really think I will, considering I have other 35's to take care of what ever might be on the menu. Go ahead and give 'em a try, I'm sure you won't be disappointed.
