On the other hand, the lighter bullet will maintain the projectile, but they may not have as much penetration. But for short-range shots, the heavier bullet will maintain momentum and cause more damage.

The 100 gr bullet has 2450 fps muzzle velocity while the 36 gr bullet has a 3750 fps muzzle velocity. But this often happens if you don’t change the muzzle velocity.īut based on the rounds we showed above, they all come at different muzzle velocities. This is because higher recoil causes the muzzle to flip, landing the bullet further away from the target. Generally, a higher bullet grain leads to higher recoil and a lower point of impact. It’s often challenging to predict the effects of changing bullet weight, but you can rely on chronograph tests from sites like or even tests from the FBI and other law enforcement agencies. The Effects Of A Higher Grain Weight With. But it’s only comparatively effective at short range. Therefore, this bullet has excellent penetration, and it fragments, causing more damage to the internal organs. 223 bullets and was designed for covert special operations.īut it still loads into standard AR rifles.īallistics tests showed an average of 2450 fps muzzle velocity before the bullet hits the target. 223 standard bullets, it still maintains a high muzzle velocity.

The 36, 38, and 50s grains appear to be the most common rounds since most rifles have a twist rate that can stabilize such weights. 223 ammo is the Varmint Grade 36 gr, which has a 3750 fps muzzle velocity.
