The SST is one effective bullet!
The SST Projectile
Today we are testing the Hornady 7.62x39mm 123gr SST. The SST features a polymer ballistic tip projectile. This polymer tip increases the round's aerodynamic capabilities. The ballistic tip also helps the round consistently expand inside of soft targets by putting reward pressure on the bullet's core. The bullet has a marketed ballistic coefficient of 0.295. This is quite low compared to most long range ammunition, but the round performs well inside of 500m.
The bullet design uses "Interlock" technology to provide consistent expansion without fragmentation. Unlike most bonded bullets, the base of the SST is the only portion of the projectile that is actually bonded to the core. Inside of the round, a small crimp that can be seen here keeps the jacket from separating from the lead core. Because the crimp is placed so low on the round, the bullet easily expands while retaining its mass.
Test Results
In order to test the reliability and precision at longer ranges, we fired the SSTs out to 338m and (not shown in video) 550m. We found that by using a MilSurp Yugo SKS we could easily hit our intended targets while using iron sights from the seated position. The SST dropped at a rate similar to the rates advertised on the box. Although the SST did not give us a spectacular performance at 550m, it would easily get the job done at closer ranges. I would recommend that this ammunition should be used within 300m.
- Average Velocity: 2266 F/S
- Max Penetration: 16in+
- Max Permanent Cavity Diameter: 1.12in
- Max Temporary Cavity Diameter: 14in
Good For Hunting?
We initially filmed this video for /u/FrankStallone69 . Frank wanted to know if the SST in 7.62x39mm would be adequate for hunting medium game. I was a bit worried by the low BC of the SST and the choice of caliber, but after testing this ammo I have no doubt it would work well. As long as the shooter places his shot well, the SST will be able to put small targets down.
