Frequently Asked Questions

How does the .45-70 Government compare to a 12 Gauge slug for bear defense?

.45-70 Government rounds like the Underwood 430gr Hard Cast offer superior penetration through hard barriers such as steel, while 12 Gauge slugs like the Brenneke Bear Protection Magnum cause more structural damage and mushrooming, though with less steel penetration. Both show significant effectiveness in ballistic gel.

What are the key ballistic differences between .45-70 and 12 Gauge slugs?

.45-70 Government generally retains velocity and energy better over distance, demonstrated by higher tested velocities. 12 Gauge slugs often have higher muzzle momentum and cause more immediate structural damage upon impact, but lose energy faster and may not penetrate as deeply through hard materials.

Which ammunition performed better against mild steel?

The .45-70 Government round punched a clean hole through 3/16-inch mild steel. In contrast, the 12 Gauge slug created a large dent and bulge but failed to penetrate the same steel plate, indicating the .45-70's superior performance against this specific barrier.

What testing methods were used to compare the .45-70 and 12 Gauge slugs?

The comparison involved testing penetration through pressure-treated pine, sand, concrete blocks, and 3/16-inch mild steel. Additionally, impacts on AR550 steel targets and extensive testing in ballistic gel were conducted to assess wound channels and penetration depth.
