Am going to work up some loads for TAC, but looking at my Hornady book and the mfg website the data seems quite a bit different... both for Hornady bullets (55gr FMJ/BT w/c, 2267 is what I'm using) I don't have it in front of me but it seemed like the low from the powder mfg was near the top end of the Hornady loads. Thoughts? Anyone else using TAC?
