For those wanting a deep penetrating all copper expanding 38SPL load this is it.Depending on impact velocity you can expect between 11 to 13 inches of penetration in flesh and bone.Buffalo Bore was able to engineer a flash suppressed powder for this load and therefore the shooter will not be blinded by his own gunfire in low light.This creates a huge tactical advantage as most civilian shootings in the US occur in low light when the criminal element is out and about.
