Dependability and durability are a must for all high volume shooters and this Wolf Polyformance ammunition will not disappoint! Wolf coats all of their ammunition with a polymer coating to ensure smooth feeding and extraction putting the shooters mind at ease with less jamming. The coating on the ammunition allows for the ammunition to have a lengthier long term shortage time in comparison to different manufacturers. Like the Military Classic line, the Wolf Polyformance line is an excellent choice for recreational shooting or high volume competition when consistency and reliability are key. Wolf ammunition is known for their 100% performance guarantee. This means that Wolf is one of the only ammunition companies on the market right now that will refund you the money for the unused portion if a shooter is not satisfied with the quality of the ammo. The Bi-Metal bullet of the Wolf Polyformance 300 Blackout rounds consists of a lead core and a copper plated steel jacket. Though the Wolf ammunition factory is based out of Russia, these 300 Blackout ammo rounds are delivered straight from sunny California. Wolf Polyformance is non-corrosive, new production ammunition in Berdan primer and non-reloadable steel cases.
