Hodgdon Lever has a burn rate between WW748 and WW760, and performs better for me than 748 in a 24" bbl 1:12 twist Remington M700 in 223. With Winchester 5.56mm military cases, Winchester Small Rifle Primers, and Winchester's 64 grain Power Point deer bullet, I get 3110 fps chronographed and good accuracy (with 26.7 grs charge) vs 3040 fps with 26.2 grs 748. Burn is not quite as cool as 748 but every bit as clean, perhaps more so. .
