Hornady 50 Cal Sabot Low Drag with 45 Cal SST Bullet - Other "easy load" bullets often fail to properly engage the rifling which does not effectively stabilize the bullet and as a result, accuracy suffers. Hornady sabots fully engage the rifling to keep the SST-ML centered and sealed during firing, allowing for maximum velocity and unparalleled long range performance. Upon impact, the Flex Tip is compressed into the front of the bullet, causing the bullet to expand.
