#194: A Conversation with the Co-Creator of the 6.5 Creedmoor, Dennis DeMille
Posted on: May 22,2025Hey, Scuttlebutt listeners. Thank you for joining us and your continued support. This week, we welcome the ballistician and co-creator of the 6.5 Creedmore, Dennis DeMille, to the show. Dennis is a veteran Marine mortarman who served as a drill instructor, was on the Marine Corps Shooting Team, and retired as a chief warrant officer before becoming the vice president of product development at Creedmore Sports (thus the name of the round) and is now the general manager of Tactical Walls. For those who don’t know, the 6.5 Creedmore is the current long-range precision rifle round for US Special Operations Command and the British Royal Marines. Basically, it’s the round bad asses use to do bad ass things. Dennis talks about his life before the Corps, his path from the shooting team to being the officer in charge of all the ranges at Camp Pendleton, and how the 6.5 Creedmore came to be. He has a really cool story about how it came to be named the 6.5 Creedmore and not the 6.5…DeMille.
Enjoy!
