I have not tried TAC in 308WW. I have had good luck with it in 223 case and wildcats from that parent case.
I see guys mentioning compressed loads like it's a bad thing. I myself prefer a casefull of powder to half empty or half full. If it is a $ thing, I won't go there. I tossed the idea of saving $ aside a long time ago, shortly after I started hand loading.
More times than not all my chrono numbers come together very nice with a full case.
I had been playing with a cartridge for almost too long. Results were scattered. Ended up with a case full of powder, everything is great now. Spreads are single digit, which can be tough to come by with some cartridges.
