I havent had any surprises substituting Lever for CFE 223 data in the Grendel. Its going to be hard to beat Lever for velocity with the 120-123 class bullets. And I always get way better ES/SD spreads with Lever vs CFE 223!
Having said that, I always work up from 5-7.5% below max charge when substituting! Starting too low can be just as big a problem, too little and the powder doesnt burn, it detonates!
