Underwood Ammo 648 Xtreme Penetrator 10mmAuto 140gr Solid Monolithic 20 Per Box/10 Case

Description

Underwood Ammo 10mm ammunition, 140 grain monolithic copper, 20 rounds per box.

Monolithic copper – the bullet is one piece of copper alloy rather than a lead core in a jacket, so it does not separate. It is also the construction used where lead-free ammunition is required.

Bullet weight is given in grains; there are 7,000 to the pound, so this one weighs 140 grains. Within a calibre a heavier bullet generally leaves the muzzle slower and carries its velocity further, while a lighter one starts faster and sheds speed sooner.

Cost per round: $2.00.

Ammunition is not a firearm and ships directly to you, though some states and cities restrict ammunition shipments or require a licence or permit. Check your local rules before ordering – if you are unsure, ask us first.
