375 H&H MAGNUM
The following data was developed in a Remington 700 Safari rifle. We removed the wooden stock and replaced it with a synthetic stock from McMillan, and added a Vais muzzle brake. We installed a Leupold 3-9x compact scope in Leupold mounts on the rifle. The rifle has a 24 inch factory barrel.
We used RWS cases and the Winchester large rifle magnum primer throughout all our testing. All groups are 3 shots at 100 yards.
