Berger Hybrid bullets are designed to achieve extreme accuracy for competitive and recreational target shooters. Berger Hybrid bullets combine a tangent ogive with a secant ogive to produce the highest possible with the least sensitivity to seating depth. This allows the reloader to take full advantage of the best features of both designs.When Berger built the 30 cal 200.20x bullet (#30417), it was in cooperation with the US Rifle Team (F-TR). This is an identical cooperation with the US Rifle Team (F-Open). They helped design, prototype, test and develop this bullet and each sale, Berger will donate proceeds back to the team to help support their efforts at the World Championships. This is "the Official Bullet of the US Rifle Team". It has been optimized for performance in a weight class and caliber that F-TR competitors and other long range shooters are gravitating toward. Its sleek design, incredible ballistic properties, and most importantly, downrange results have solidified this as the Official Bullet for the US Rifle Team (F-TR) to compete in the World Championships.
