Owner of Buffalo Bore Tim Sundles on Buffalo Bore Heavy 38 Special Ammunition:
For those wanting a deep penetrating all copper expanding 38SPL load, this is it. Depending on impact velocity, (barrel lengths and target distance vary) you can expect between 11 to 13 inches of penetration. Buffalo Bore was able to engineer a flash suppressed powder for this load and therefore the shooter will not be blinded by his own gun fire 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.
See the below real world velocities fired from real world revolvers, not extra long laboratory test barrels that give false high velocities, that cannot be duplicated in real life. With Buffalo Bore Ammunition, you'll always get real world, useable velocities.
This load is safe to fire in all 38SPL and all 357 firearms that are in normal operating condition. This cartridge is designed so the bullet will not jump crimp when subjected to recoil from firing in super light 12 OZ revolvers, provided you do not subject any cartridge to the recoil of more than ten to twelve firings.
