A few of you mentioned CFE 223 and Win 748, those would be good option because I also reload 223 and would be nice to have one powder for both.
Having trouble finding either though.
You might try and locate some BL-C by hogdons powder....
No idea how it will work in 6.5 CM, but .223 and .308 it does impressive things.
bearhunter, your thoughts ?
