I selected two Berger VLD bullets, the 1st of which was the business's 190-grain Searching version.
The recovered diameter (RD) was calculated in inches through the deal with with the bullet in two places and represents accurate 1680 powder the average of those two measurements. The recovered body weight (RW) is the load in grains of the largest portion of the bullet. Tests was done at an elevation of 2,200 toes earlier mentioned sea degree.
