308 VS 6GT

YouTuber Averageshot documented his thoughts and testing of the 6GT round vs .308 in his video titled ‘308 vs 6GT Groups at 1000 yards'. Before we dive into the video, let's take a quick look at the 6GT round.

The 6mm GT round was created by GA Precision with the goal of improving upon the 6BR rifle cartridge. A main benefit of the 6GT is that it feeds more reliably than the 6BR in magazine-fed rifles due to its 35-degree shoulder angle. The measurements of the 6GT are mostly between 6BR and 6mm Creedmoor cartridges, and the brass is capable of being reused more than other similar rifle calibers. 6GT is also easier on barrels than 6mm Creedmoor while having an average muzzle velocity of 2850-2975 FPS.

Averageshot shoots eight rounds of .308 through his rifle at a steel plate from 1,000 Yards at the beginning of the video. This rifle is equipped with a bipod, scope, camera, and MDT ACC Elite Chassis. He achieves a total spread of 15.9 inches in harsh wind conditions and misses the steel plate twice. The host then turns the range over to his friend, who shoots his 6GT rifle at the same target.

The 6GT rifle build then shoots a 13.08-inch spread across eight rounds fired at the same target from 1,000 Yards, with a 6-inch spread not accounting for one errant shot. The 6GT remains supersonic at this distance, unlike the .308 rounds fired by the host's build, despite its long barrel.

Averageshot is surprised that despite its subsonic flight at 1,000 yards, the .308 rifle made consistent impacts and performed almost as well as the 6GT chambered rifle. With limited content and resources pertaining to the 6GT on the internet, this video comparing its performance versus the common .308 provides data that might be worth considering by those looking into the 6GT round.
