300 WIN MAG 178 GR. (11,5 g)  
TAP PRECISION®
NO. 82045
Application:  Precision
Hornady® 300 Win Mag 178 gr. (11,5 g) TAP Precision® 
ammunition was designed as an improvement on the 
178 gr. (11,5 g) TAP Precision® load by incorporating the 
Match bullet. Offering higher velocity and energy that 
law enforcement professionals may require over the 
standard 308 Win, makes this a great alternative to utilize 
in a variety of situations. The tip initiates expansion of the 
Match bullet, ensuring uniform expansion and penetration 
through a variety of barriers, while mitigating liability due 
to over-penetration.

300 PRC 225 GR. (14,6 g) TAP PRECISION®
NO. 81215
Application:  Precision
Designed and adopted to fulfill a specific need within the 
Department of Defense, this cartridge is an efficient, non-
belted magnum featuring a 225 gr. (14,6 g) ELD® Match 
bullet with a Heat Shield Tip. While utilizing the same bolt 
face as a 300 Win Mag, the 300 PRC headspaces off the 
shoulder rather than a belt, providing superior accuracy. 
Following similar design characteristics present in the  
6.5 Creedmoor, the 300 PRC provides higher velocities 
and the ability to run longer/heavier bullets than the  
300 Win Mag, making it a much more versatile cartridge.
