The Sako TRG Precision 157A uses an 11.3-gram or 175-grain Lapua Scenar-L OTM precision bullet. With a muzzle velocity of 800 m/s and a ballistic coefficient of 0.472, this cartridge is suitable for competition and long-range precision shooting. Suitable for use in Long-range precision shooting Competition shooting PRS training Practicing ballistic corrections .308 Win precision rifles Shooters who prefer the Scenar-L bullet Why choose TRG Precision 157A? 11.3 g or 175 gr bullet Lapua Scenar-L OTM bullet HPBT construction Muzzle velocity 800 m/s Ballistic coefficient 0.472 Consistent velocity and dimensions Good wind resistance 20 cartridges per package Technical specifications Manufacturer: Sako Series: TRG Precision Caliber: .308 Winchester Bullet code: 157A Bullet weight: 11.3 g / 175 gr Bullet: Lapua Scenar-L Bullet type: OTM / HPBT Muzzle velocity: 800 m/s Ballistic coefficient: 0.472 Package: 20 cartridges Country of manufacture: Finland Set includes 20 × Sako TRG Precision 157A .308 Win cartridges Frequently Asked Questions What is Scenar-L? Scenar-L is Lapua's boat-tail Open Tip Match precision bullet, manufactured with minimal dimensional and weight variations. Is 157A suitable for hunting? This cartridge is developed for competition and precision shooting, not for hunting applications requiring controlled expansion. Is 157A better than 140A? Not necessarily. The 157A has a slightly higher ballistic coefficient, but practical accuracy depends on the specific rifle and production lot. When is 157A the right choice? The 157A is suitable for demanding precision shooters whose rifle performs well with a 175 gr Scenar-L bullet. For shorter distances or if you prefer less recoil, consider comparing the 168 gr 141A variant. Recommendations Test the 157A cartridge in your rifle at least at 100 and 300 meters. A small group at short range does not fully describe the bullet's behavior in crosswinds or velocity consistency. If possible, measure the muzzle velocity of ten shots and enter the average result into a ballistics program. Do not mix 157A data with other 175 gr TRG Precision data. Bullet geometry and ballistic coefficient may differ even at the same weight. Scenar-L precision ammunition for .308 Win rifles Sako TRG Precision 157A combines a 175 gr Scenar-L bullet, 800 m/s muzzle velocity, and a ballistic coefficient of 0.472.
