I just received my shipment of this ammo and all I can say is, Wow! This is gorgeous ammo. When I look at the business end of this bullet, the first image that comes to mind is 'largemouth bass'. The opening for the hollow point is much larger than Ranger-T for example. The inside of the hollow point is smoothly filled with a silverish concave metal, presumably lead. This appears to be very high quality JHP. What's the difference with commercial HST? Three things: the box is plain, although clearly identified as Federal HST; the spec for fps is much tighter than civvy ammo (more consistent); and the brass case is not nickel coated. Nothing but the best for our Feds, and now me. Get it while you can.
