The six-point-five Grenny is one of the more exciting pieces of ballistic hardware to hit the scene in this century. Finding the ammo can still be a hassle, but you came to Cheaper Than Dirt specifically because you enjoy avoiding hassles. You just want to order the whole case of Sellier & Bellot goodness and be done with it.

This round’s bullet is a plain and humble full metal jacket. Lead core. “CuZn 10” jacket, meaning it’s 90% copper, 10% zinc. OAL of 2.224”, with a power factor of 319.3. All of that is to say that this round’s specs are unextraordinary. It’s well made, but it’s not redefining the meaning of “six-point-five Grenny.”

Its Czech manufacturer recorded this round’s muzzle velocity with a 23.5” barrel; .400 G1/.202 G7 ballistic coefficient. Upon plugging the right figures into our ballistic calculator, we came up with these elevation data:
➤ 0 yds: -1.50”
➤ 100 yds: 2.4”
➤ 200 yds: 0.0”
➤ 300 yds: -9.9”
➤ 400 yds: -28.7”
➤ 500 yds: -58.6”

Sellier & Bellot doesn’t throw shooters curveballs in the form of cheap or unusual components. Steel-jacketed bullets? Corrosive primers? Remanufactured brass? You won’t find any of them in this case of ammo’s 30 individual boxes.
