.50 AMMUNITION EFFECTS
The .50 caliber round is optimized for penetration at long ranges (about875 yards, or 800 meters). For hard targets, .50 caliber penetration is affected by obliquity and range.
The .50 caliber round can penetrate all of the commonly found urban barriers except a sand-filled 55-gallon drum.
Continued and concentrated machine gun fire can breach most typical urban walls. Such fire cannot breach thick reinforced concrete structures or dense natural stone walls. Internal walls,partitions, plaster, floors, ceilings, common office furniture,home appliances, and bedding can be easily penetrated by .50 caliber rounds.
