[QUOTE="Trickymissfit, post: 766610, member: 25383"] I bought a couple boxes of 130 grain SST's several years back, and promptly loaded them up fairly hot, but not close to max velocity. Think I was seeing something like 3350 fps, and it looked like there might be another 75fps to maybe even 100fps more velocity left in it. At the range things started to act kinda funny with big holes in the cardboard backup on the targets (fist sized holes). But then I noticed that about one in four or five bullets completely missed the target. I had a buddy stand behind me to watch and see where they were hitting. There was no hit anywhere down there. I called Hornaday the next day, and they told me the bullets were probably blowing up in flight(never had that before in anything). After telling them what I was seeing out of the chronograph, and the loads I was using the let out a sigh! Said the rounds were designed for a max of a little over 3000 fps. But he also said that at 400 yards I'd be fine. He recommended two or three other bullets or better yet move up to 150 grain bullets. So I tried some Speer 150 grain BTSP bullets I had left over from a 270 Winchester project. Ran them right at 3200fps, and started shooting 3/4" five shot groups right away. I got 2.5" groups at 250 yards out of them, and really never bothered to seriously change the loads (ran out of 3100 powder) This year I'm going to try Magpol as the Accurate folks sent me some loading data using that powder (If I can ever find it again).
