The DRSS is a group of guys that got together thru
www.accuratereloading.com they usually try to put a hunt together in the spring.
I have not taken a elephant with a 450/400 but I have 2 friends that have and found it perfect. I even had one of my friends that has taken a couple of eles with a 9.3x74R in Zim.
The 450/400 is a sweet little double, and if your not a handloader then 75 dollar a box hornady sounds alot better than 250 dollar 470 ammo.
