I built a custom rifle on a Winchester action and chambered in the .375 Remington Ultra Mag. Something I plan to take to Africa sometime down the road. I started loading with 94.0 grains of IMR4350, and a Remington 9 1/2M primer and a 260 grain AccuBond. My rifle allowed me to load up to 96.0 grains with excellent accuracy and no visable signs of excess pressure. My velocity is a little different than that posted in Nosler's releading manual. My muzzle velocity is 3,140 fps with the Chrony setup 10 ft from the barrel.
Being anxious to fire my new creation at something more than paper and water filled milk jugs, I took it on a Wyoming migration elk hunt this past week. Sometime around an hour after day break I found myself watching a heard of approximately 200 elk file up the canyon and headed in my direction. There were a total of three bulls in the group, all branch antlered and all in the rear of the long line of migrating elk. Every one of those elk filed past me at about 150 yards. When the largest of the three bulls was nearly straight across from me I give a couple soft cow calls to stop him. Once stopped I put a 260 grain freight train through the lower part of his right shoulder. He stumbled twice and piled up.
The bullet completely vaporized his shoulder bone about 8 inches above his knee, put a nice hole completely through his heart and exited the other side. The exit wound being no larger than a silver dollar.
It's quite a bullet to withstand that much velocity and bone and stay together enough to exit the other side of an animal with only a silver dollar size hole. I know, it's a little much for elk, but it worked.
I have photos of the bull, but have know idea how to post them. I'd be happy to email someone with the photos if they would like to post them as part of this thread. The 6x5 bull scored out at 320 before any deductions.
