The smallest group with the 168 grain BTHP was 0.62 inches with 47.0 grains of BL-C(2). All loads with the Lapua Scenar bullets grouped less than 1 minute of angle.
All the above loads were assembled using Lapua 168 grain BTHP Scenar bullets. The rounds were loaded to an overall length of 2.800 inches. The loads were shot in a Steyr SSG in .308 Winchester calibre with a 26 inch barrel. The velocities were recorded in feet per second ( FPS ) using a CED M2 chronograph. The velocity was an average of three rounds. The extreme spread is the difference between the highest and lowest velocity in feet per second ( FPS ). The rifle was supported at the front by a Harris bipod and at the rear by a polymer bead filled butt bag. All loads produced groups below one minute of angle at 100 yards range. If all your shooting is done out to 200 meters then the lower powder charges will work OK. If you are shooting out to 600 yards the higher powder charge will give you a flatter trajectory and better bullet stability at the longer ranges.
146 grain FMJ bullets
In addition to using the 168 grain BTHP bullet, loads were assembled using 146 grain FMJ bullets, as this is also a popular bullet type and weight in this calibre. These loads were again assembled using both BL-C(2) and H4895 powders. The rounds were loaded to an overall length of 2.800 inches. The loads were shot in the same Steyr SSG in .308 Winchester calibre with a 26 inch barrel. The velocities were recorded in feet per second ( FPS ) using a CED M2 chronograph. The velocity was an average of three rounds. The extreme spread is the difference between the highest and lowest velocity in feet per second ( FPS ). The rifle was supported front and rear as before. All loads using 146 grain FMJ bullets produced groups of between 0.72 and 1.13 minute of angle at 100 yards range. If all your shooting is done out to 300 meters then these loads will fulfil your needs.
