[QUOTE="Greyfox, post: 1459234, member: 10291"] Hear is an excerpt from an RBros review article that quotes David Tubb on the “rebated” 6mm DTAC... “David Tubb: Here are couple of reasons that the RBT design was selected. These are not based on the RBT being a ballisticaly superior to a conventional boattail design. If the new DTAC 115 RBT was produced in a conventional boattail shape the G1 (1000yd) BC numbers would be very close. The Rebated Boattail design was selected because; 1. Easier to precisely hold tolerances when manufacturing the 7 degree boattail angle– most conventional boattails have 9 degree angles (or greater). 2. RBT more efficiently opturates to the bore of the rifle barrel when fired. (Mimics a flat base bullet design). This will allow the RBT design to extend your accurate barrel life by reducing gas leakage around the bullet when fired in a worn 6mm throat.” Full article: [URL]http://rbrosrifles.com/new-6mm-115gr-dtac-from-david-tubb/[/URL] [/QUOTE]
