What is the optimal barrel lenght and twist rate for the 350 legend?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on May 16, 2023

Optimal barrel length for a 350 Legend barrel is between 16" - 24" in length with a 1/16 twist. A 24-inch barrel averages 100 fps faster and 10 percent more bullet energy than a 16-inch barrel. A barrel shorter than 16-inches will begin to reduce the effective range below the established 250-yards.

For the 350 legend, does that require a caliber specific BCG or will a .223 work?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on November 28, 2022

350 Legend uses the same case head dimensions as 5.56, so you can use any standard 5.56/.223 BCG in your AR build.
