Hornady actually specifies a max of 3600 fps for the 50 grain SPSX, it used to be right on the box. I haven't looked at any of the new boxes I bought a couple of years ago. I had a 1:8 twist 223, it would vaporize the 50 grain SPSX at 3,600 fps. The 55 I have pushed over 4000 in a 22-250 with a 1:12 with no problems.
Both are excellent fur friendly bullets.
