Ballistics
Velocity only, no drag model: no published ballistic coefficient is on file for .30 Remington AR, so this is the shape gravity alone gives the advertised velocity. Drag would steepen it. The tool below solves real loads through their published G1 or G7 model.

History
Remington launched the .30 Remington AR in 2008 for its R-15 hunting rifle, pitching it as a way to get true .30-caliber deer performance out of an AR-15-size gun without stepping up to the bigger, heavier AR-10. To fit the fat, rebated-rim case into that platform, Remington built a unique bolt that melds small- and large-frame AR parts. It earned SAAMI standardization but never caught on: factory ammo was always thin, and Remington's 2020 bankruptcy finished it off. Today it's a used-market curiosity, capable on paper but a headache to feed.
