I have used this before in 135Gr and have some in ammo safe(never had any porblems in XD, XDM or 24/7). Hydro Shoks are a older design from federal. According to what i've learned( internet and forums), they can fail to open(mushroom) at times due to heavy clothing. Federal HST is the new thing from Federal for SD.
That being said i have some loaded in my XD right at this moment, i prefer the 135gr to the lighter bullet weights.
