The North Fork CPS performs like no other bullet you have ever experienced. The cup point expands up to 2/3 of caliber size, creates a wound-channel 3 to 5 times wider than caliber and penetrates like a typical solid. Several of North Fork customers have taken buffalo with the .375 350 grain CPS and reported that the bullet penetrated through the entire length of its body. That is what you should expect from a premium bullet.All North Fork solids are safe for modern double rifles as only the Smart Bands of the bullet are touching the rifling. This minimizes the stress on the barrel imparted by typical solids. North Fork Softs and Solids are also designed to hit the same point of impact. This is not loaded ammunition.
