[QUOTE="esshup, post: 2277475, member: 11101"] I've "poofed" 175g 7mm SMK's. My only thought was the throat got a wee bit rough and weakened the jacket enough so that they exploded around the 50 yd mark. 1:9 twist 3490 fps. The first 200 shots were fine, then things started to go haywire. Nothing made it to the 100 yd target and when I lifted my head from the scope to try and see the bullet impact that's when I saw the grey cloud. I also shot that gun at night, no external light with a GoPro and another video camera. Wanted to see the size of the blast flash from the muzzle brake. In ONE frame in ONE of the videos there is an orange streak in front of the muzzle blast that looks exactly like a bullet. I can't explain why it showed up on that one frame in the video, nor why it was that color. There was no external light source except a full moon which was behind me as I shot. [/QUOTE]
