If the data sheet you are referring to is the sheet included in Lee Dies, toss it out. Now. Its garbage. I've encountered truly shitty data on Lee data sheets before. Its not to be trusted. (And if you are using those damned little dipper thingies, toss em and get some sort of s decent scale too.)
Some loads will compress the powder. Get a decent loading manual. Many will state a load is 95% capacity, 98%, 100% and occasionally as much as 106% of capacity. Anything over 100% is a compressed load. No problems. Alliant's manual (available online, as is Hodgdon) will show loads like the following max load: 308 Win, 150 Speer SP, RL15, CCI200 primer, 2.700" COL, IMI case, 49.0C charge weight, and velocity 2919. The 49.0C means 49.0 grains is a compressed charge. You'll feel powder crunch and crush as you seat. its fine.
For what its worth Alliant's publish reload manual shows 14 different loads for 308 Win. 8 of the 14 max loads are compressed charges. Its fairly common.
