    has anyone done this or heard of anybody doing this? today i took an old factory bbl and cut the old chamber off and rechambered it using a 7mm wsm reamer and 243 wssm headspace gauges, headspacing like you would an ackley. i only loaded up 1 test round using necked up and trimed 243 wssm case and shot it. it gave it a little more bit of a sharper sholder and pushed forward a little bit giving it a lttle more case capasity. im going to call it the .284 thunder chicken. i will keep everyone posted in the next few days of speeds this little thing can do. should be a good lttle plinker round and even hunting i guess. huntinfool18
