It's a classic compromise bullet, between the 124gn and the 147gn. I personally don't like them (the 135's) for a number of reasons.
Firstly, I called Federal to get some information from them, and they pretty much had nothing to say about the 135gn loading, but were all too willing to chat about the other two loads in 9mm.
Second, when I examined the two boxes that I had bought, I found that about half of the rounds had less than standard center posts, and a few had them missing all toghther!
Lastly, FTI tested them and showed how terrible they are in several standardized tests. The same tests, incidently, where the 124 and 147gn HydraShoks shined.
So, given that, I decided to just dump them downrange. WOW. S&W Sigma 9mm, in great, although 6000 rounds, condition. Placement at 25yd was about the same as any high performance loading, but the recoil was terrible! Much harsher than the other offerings. And EVERY ONE of the spent cases showed major bulging. I've never seen anything like it from any of my guns. I took the remaining box of bullets back to the load bench, took 'em apart (to use the brass), and put them up on the shelf as and example of "What Not To Buy", 'specially without knowledge of performance.
Stick with the proven 124 or 147gn loadings, your life is worth it.
