Characteristics
This Stage 3 Afterburner is optimized for .308” caliber rifles sporting a 1:10” twist with magnum level powder capacities but is plenty capable in a 30-06 as well. Loaded in a 300 Win Mag, one could hunt the world with few limitations. The nose length is short enough to allow flexibility in seating depth adjustments for all magazine scenarios.
Like other Stage 3 releases, the loading behavior of this bullet is incredibly forgiving, thus reducing variation and inconsistencies around component selection and seating depth adjustments. This allows the ability to find accuracy nodes with ease and with a variety of combinations.
The terminal performance of this bullet results in a substantial trauma path for a .308” caliber bullet making it capable of hunting all game in North America and most of Africa. For brown bear, our preference is a bit more bullet weight, but the 180gr will perform well under those circumstances, nonetheless, and the impact reaction will be noticeable on the intended target. The shrapnel damage is high and the penetration deep for hard angled shots, even on heavy bone, while at the same time capable of full deployment on a broadside hit of a smaller animal at 1650 fps impact velocity making the flexibility of this bullet virtually unrivaled.
There’s something very American about a .308” caliber with a 1:10” twist, and we’re excited to release this Stage 3 bullet maximizing the potential of that combination. We know this one will be a welcome addition for our customers with high expectations!
