Having just spent a few hours looking for an accurate load for 115 DTAC's, the best (of those powders tried) was N560, where 54g in a 32" barrel was clover leafing at 100 yds and measuring 3,250 fps.
Data not offered as other than my own observations, which others might chew on - I started off at 51.5g.
