Black Butterfly Ammo CTX Migration

Condition:   New
Velocity No1:   1675 AMV FPS
Velocity No2:   1850 AMV FPS


This round was created for target and or close quarters training applications. Due to the fact the projectile is lead free, it can also be used in lead free ranges and in states like California that are gradually phasing out lead projectiles.

This monsterous projectile was designed to give the shooter the maximum OAL possible which we feel dramatically increases its accuracy. The shape of this projectile also insures it will feed properly from any standard GI mag on the market.

Like the TSX High and Low Velocity, we offer this projectile in two completely different loads. The first (No1.) is a lower velocity load intended for frangible round and or training applications. The second load (No2.) runs approximately 200 FPS faster and is intended for target and plinking applications.

This is an exclusive product manufactured by CTX to Black Butterfly Ammunition’s specifications.

This projectile is also offered to the public in 250, 500 and 1,000 count bags for reloading.
