Browning Speed 7mm Rem Mag with Hand Loaded 160g Nosler Partition on Black Bear

The Nosler Partition bullet is renowned around the world for penetration. I used it exclusively on an African Plains game hunt thus my selection for bear hunting. My Browning Speed in 7mm Remington Magnum was my choice. 

 

On my Maine Foggy Mountain black bear hunt, I tried to get 175g Partition bullets for my bear adventure. Unfortunately, they were not available, luckily, the 160g Partition bullets were.

I have chronograped my new hand loaded 160g Nosler Partition at around 3050 fps using IMR 4831 powder. That is cookin’

As you can see below, I shot my bear in the slightly quartering toward front left shoulder.

The bullet exited the off side ribs wrecking the lungs. No death moan aka no lungs. I estimate the terminal energy at around 3400 ft-lbs. Wow! The boar went 25 yards and piled up. Funny, I never felt the recoil estimated to be near 28 ft-lbs.

On inspection during meat processing, the wound site had a 2 inch by 3 inch wide football-like cavity beginning at around an inch in after entering. I did not hit shoulder bone. 

The bullet continued through lungs, ribs and exited. Was that overkill? Many bear hunters use the 300 Win Mag with 180g bullets. delivering 3700 ft-lbs at 25 yards and hitting you with 35 pounds of felt recoil.

If I go on a trophy black bear hunt, where bears often exceed 300 to 400 pounds, I may opt for a 300 Win.

Big Canadian bears can be aggressive, like climbing into your treestand and popping their teeth. 

If you can handle heavy felt recoil… not a problem.

Good Hunting!
