The 9mm EMB (Expanding Mono Block) is a homogenous copper alloy (lead free) bullet loaded using a lead free primer. The bullet and expansion cavity are swaged and shaped to expand on contact with tissue (like a hollow point) but the characteristics of the bullet (low weight, high velocity, malleability, and shape) are that it opens and expands quickly on contact, often leading to less penetration than standard lead core/copper jacketed JHPs. The three petals of the bullet peel back on contact and most often stay attached to the rest of the bullet while penetrating and expanding. The center post surrounded by the three petals continues the penetration as the bullet expands. A great round for self defense or law enforcement/protection in densely populated areas or buildings where over penetration is of concern. Operates at standard SAAMI pressure, not +P. Added velocity is due to lighter weight compared to standard weight 9mm JHPs. This is loaded ammunition.
