Just opened my new box of 115 DTAC's. Noticed that without adjusting my seating die from when I ran out of the "old" bullets, the new ones have an OAL that is 0.007" longer. Base to ogive measurement is still the same.

Has anyone that shoots the 115 DTAC (regardless of cartridge) had to change any of their load data when switching from the "old" to the "new" to maintain the accuracy of the former bullet?

I know I'm gonna have to reconfirm drop data, and am not worried about pressure with the powder workup I've been using with the "old" bullet. Mainly concerned about accuracy before I load a bunch of them with the powder charge that has been working so well.

No, you don't have to change load data. The only reason the OAL is longer is that the new bullets are pointed. As far as drop data, use eskimo ballistics, they have a "pointed" option for their program that is dead nuts.
