Africa, Argentina, Canada - I have been very effective with my 45/70 rifle using 540gr. Garrett Hammerhead Ammunition. However, I run out of range at 150 yards. When Hornady began to offer "Superformance" .375 Ruger ammunition - I saw that the ballistics were exactly what I always wanted.

Knockdown power for big game - Wow! What a fantastic load! Thank you Hornady; 375 Ruger outperforms the old ,375H&H, and my new rifle has a 25" barrel, so real knock-down power is available out to 400+ yards and beyond...
