I have some TMK, 69 and 77gr 223, have not yet got them to do better than the SMK factory stuff from ADI and PMC. I am 150fps short on velocity mind. Just got some BM2 as I hate compressing powder (2208) and its going to be max loads by the look of it to get there.
What gun btw? ie a bolt action, AR15 or what? Its also a hell of a MV for a 223 69gr...
anyone else find you need to be hot with a 223 and the SMK/TMK btw?
