Product Information

The Hornady® SST® (Super Shock Tip) is designed to deliver tremendous shock on impact while expanding quickly and reliably, particularly at higher velocities.

Flat shooting and deadly accurate, it's an ideal bullet for whitetails, as well as most North American game animals from antelope to moose and similar-sized African plains game. The SST® creates a devastatingly large wound channel.

  • POLYMER TIP:  Upon impact, the hard polymer tip drives into the lead core like a wedge, initiating lightning-fast, yet controlled expansion.
  • SECANT OGIVE, BOATTAIL PROFILE:  Incorporating the pioneering Hornady secant ogive design, the tapered point, increased bearing surface and more aerodynamic profile, combined with a boattail base, makes the SST® more efficient with less drag and greater stability.
  • CANNELURE:  A mid-body cannelure helps keep the core and jacket together while providing a consistent, accurate crimp during the loading process.
  • INTERLOCK® RING:  This Hornady exclusive design mechanically locks the core and jacket together to maintain bullet integrity during expansion, ensuring maximum weight retention and increasing the chances of complete pass-throughs.

This is not loaded ammunition.

Graf and sons.

By David M. on Dec 19, 2023
Best bullet choice for my AR47. Very tight groups at 100. Absolutely lethal on varmints and deer. Graf and sons were awesome. Very fast shipping great customer service.

Awesome product

By Vincent S. on Nov 09, 2023
Quality product with fast shipping. Can't wait to get out to the range to try them out

Great ak boolet

By Byron H. on Jul 24, 2023
Loads pretty easy in Belom brass. Over AA1680 and CCI 41's, I'll get about 2inch groups at 100 yds consistently.

Hornady SST .310 123gr

By Douglas G. on Jun 19, 2023
Great bullet for varmint and deer. Good penetration and expansion. This is often hard to find as it is a popular for reloaders. Same bullet as in Hornady’s Black line. Runs well in bolt actions. I have used in semi autos as well.

Excellent grouping @100yds!

By Randy H. on May 23, 2023
My Ruger American Ranch and these bullets are a perfect match. Using X-Terminator I will get a 3 shot touching group @100 yard.

Accuracy Potential

By Curtis W. on Mar 21, 2023
Generally the SST's are very consistent and will aid in accuracy. The Ruger and Howa bolt guns will absolutely love these when a load it worked up. They shoot a fair bit better is SKS's than ball ammo. Outside of hunting the other thing they hurt is the pocket book. Just glad they are available at Graf's.

Excellent bullet.

By Patrick B. on Mar 03, 2023
These are the most accurate projectiles I’ve ever used when loading 7.62x39mm.
Beautifully made and never any jacket shaving when loaded.

accurate, effective, and cost effective.

By Greg B. on Feb 20, 2023
I use these Hornady 123gr SST bullets in 3 different cartridges. They shoot well in all of my rifles, and have very good stopping power on white tail deer. If you do your part pointing the gun gun and pulling the trigger, these bullets will not let you down. they are a great economical alternative to of the more expensive copper solid projectiles that are available. I highly recommend these for use in any caliber.

Great for Whitetail!

By Robert W. on Jan 10, 2023
As the name implies these bullets deliver amazing shock even at reduced-recoil velocities. Have dropped several white tails in their tracks with both 125 grain and 150 grain SSTs. For elk I’d go with something different, but for deer these cannot be beat!

Hornady 123 grain 310. bullet

By Billy G. on Sep 02, 2022
Used these to sway out bullets in Tula 122 grain FMJ. Worked perfectly to reproduce hornady 123 grain SST round since they are unobtainalbe. Worked perfectly!

New to reloading 7.62x39

By Ronald B. on Aug 15, 2022
Seems to be a decent number of choices of powders for this bullet.

Hornady 7.62x39 (.310) 123 gr SST bullet.

By Shad O. on Jul 22, 2022
Ruger American Ranch loves these SST bullets. My rifle shoots them sub MOA all day and they are devastating on Whitetails.

Good Groups

By Greg S. on Nov 10, 2021
These bullets work well in a 7.62x39 bolt action. .311 diameter would be even better, but these are reasonably accurate at 100 yards.

Hornady .310 sst 123 grn. bullets

By Bruce H. on Oct 30, 2020
I have excellent results with this projectile out of a 16" AR-15. Consistent sub moa accuracy at 100 yds. with Accurate 1680 powder. Has been my go-to deer rifle for the last three years.

Hornady .310 7.62x39

By Alexander D. on Oct 30, 2020
Very versatile bullet. Not as fragmenting as something like a nosler BT but more rapid expansion and energy transfer than a bonded bullet. Have had great success taking game in other calibers (139gr 284 SST on a 7 rem mag is a WMD for whitetail) so I figure it should make for a decent defense round considering the limited options for 310. Almost as important they load easy, feed with no setback, and seem accurate.

Hornady 7.62x39 (.310)

By Jackson S. on Oct 29, 2020
This ammo is great. It's been consistent with my loads and has incredible accuracy. Really good for the price. I load these for defensive rounds and they do a amazing job in ballistic gel


By Bobby S. on Apr 03, 2020
These are great little bullets,straight flight good penetration and expansion, much better than military surplus, will buy more

Great bullets. Use SSTs in multiple cartridges

By Martin F. on Feb 19, 2020
I've had great success with SSTs in a lot of different cartridges. They have their limitations and are not for shoulder bone shots. SST=Super Shock Tip and they mean it. Stay in the ribs and they perform wonderfully. Flat base in this offering but very accurate.

Hornady 310 diameter 123 grain SST bullet

Excellent product performed as advertised.

Hornady 7.62x39 (.310) 123 gr SST bullet.

By Jeff O. on Dec 17, 2018
This is the same bullet used in the factory loaded Hornady Black 7.62x39 ammunition. In my Ruger American Ranch Rifle at 100 yards I can obtain 1 inch or less 3 shot groups with this ammunition. The bullet flies well. I want to develop a handload with this bullet that is equivalent to the factory load and am sure that I can obtain it.
I'm planning a wild Hog hunt and would like to make head shots if possible. This bullet is up to the task. I have shot deer with the .270 150 gr SST and they are devastating.
