I have built 2 – 375 HH rifles designed around this bullet. Each of these consistently product sub .25 groups at 100 yds. I have tested them to 900 yds where they produce sub 5″ groups which is amazing for
this caliber. Recently one of my clients took his 375 HH to West Texas where he and a his friend took Nilgai – one at 385 yds the other at 425 yds. Both animals expired within 5′ of the bullet impact!
In two weeks my wife will hopefully be trying this bullet on big Brown bear on the Peninsula in Alaska.

Mike sent me his wife’s success photos and story:
Steve: Please add to my review.. As promised.. this is my follow up review on the 276 Hammers..
Alice ( my wife of 46 years) took a dream size 10’2” Brown Bear on the Alaskan Peninsula !
The 276’s running at 2745 fps.. hit the big boar in the center of this shoulder as he walked
broadside to us at 222 yds.. on the bullets impact (the whop) .. was super loud ! The boar’s chin
literally bounced 6” off the ground! To say I am impressed with the stopping power of these bullets
is an understatement! Thanks so!
