PowerBelt Aerolite Bullets are revolutionary in their performance and design. The Aerolite is specifically designed for 100 grain propellant charges, and unlike the sabots, these bullets are full caliber in size. They are extremely easy to load due to their .001” under bore diameter. PowerBelt's patented snap-on on base gas seal eliminates gas blow by, and gives you the optimal flight performance and down range accuracy you desire.
