416 Rigby is one of the calibers that I love the most, this is the caliber of work in Mozambique and South Africa, but it was hunting water buffalo in Brazil that I definitely fell in love with the caliber. Among those I hunted alone and those I hunted with clients, I have 154 hunts, most of them photographed and documented, so I have vast material related to ballistics of this caliber to share here with you. All the ammunition I use is made by me, with time patience for premium bullets. I use 400 Grain A-Frame tips, TSX barnes and monolitic solid nosler, I also used a lot of 410 Grain Woodleigh Weldcore. the 416 is an old caliber (1911) that has great volumetric capacity (made to accommodate cordite) and due to its large capacity it allows a safe pressure even in hotter loads, work with the tips of 400 grains at 2,500 feet, this causes effects spectacular in the buffalo. I already shot so much with my Ruger magnum that I no longer feel uncomfortable with the setback .. I am new here in the group, but slowly I will post my experiences. Tomorrow I travel again, I am going to hunt buffalo in the "Mato Grosso" swamps. Let's see if the rain gives them a break! sorry for the bad english!
