This auction is for one box of 100 Hornady 150gr .312" diameter SST projectiles. I have three full boxes for sale. Perfect for 303 Lee Enfield or other 7.7mm caliber rifles. These are an excellent light to medium game animal projectile. Unfortunately Hornady appears to have currently stopped production of these projectiles.

Nathan Foster from Terminal Ballistic Studies has this to say about the SST; "This is an excellent bullet, a stout flat based design, the flat base working well in the typical 1:10 twist rate of the Lee Enfield while also helping the bullet to maintain integrity after impact. This bullet has the typical tough jacket of the SST while having the deep skives within its ogive to promote rapid expansion and energy transfer. The Hornady SST is one of the best things to happen to the .303 British in many years. Like the traditional 150 grain Interlock, the SST does its best work on game weighing under 90kg (200lb) but due to its design can handle heavier game weights if need be. Wounding is violent and penetration is fair, the SST often producing reasonably wide and free bleeding exit wounds on medium game. This bullet also produces exceptional performance at lower impact velocities, shedding weight and ensuring disproportionate to caliber wounding in the absence of high velocity. As with many of its SST kin, the .312" SST bullet produces excellent performance down to 2000fps, maintaining the ability to produce fast bleeding wounds down to velocities as low as1600fps depending on game body weight resistance."
