Product Information

Hornady's traditional line of bullets feature exposed lead tips for controlled expansion and hard-hitting terminal performance. Most have their pioneering secant ogive design — one of the most ballistically efficient profiles ever developed. Most feature Hornady's exclusive InterLock® design — a raised ring inside the jacket that is embedded in the bullet's core that keeps the core and jacket locked together during expansion to retain mass and energy.

  • INNER GROOVES:  Strategically weaken the upper section of the jacket, ensuring consistent, controlled expansion, even at long range.
  • TAPERED JACKET:  Jacket thickness is precisely controlled for expansion at all velocities.
  • ONE-PIECE CORE:  Does not separate like two-piece divided cores. The InterLock® retains more mass and energy for deep penetration and large, consistent wound channels that ensure quick, clean kills.
  • CANNELURE:  Provides accurate and consistent crimping and also works with InterLock® ring to ensure the core and jacket remain locked during expansion.
  • INTERLOCK® RING:  The raised InterLock® ring is embedded in the bullet's core, ensuring the core and jacket are locked in one piece during expansion to retain mass and energy.

This is not loaded ammunition.

Hornady .312 bullet

By Wiliam B. on May 11, 2023
Does well in a oversize 7.62x54 bore or worn camber throat on a Mosin Rifle

Good accuracy on both Mosin and Enfield

By Loc N. on Apr 28, 2023
Originally got these for the Enfields but find them good on the Mosins too. Actually got one of the Mosin to group 2 in at 50yds...for this Mosin it was a miracle !

Hornady 174 gr round nose

By John C. on Apr 12, 2023
Perfect for my SMLE. I load at lower charges and they group and function well. Great quality from Hornady!


By Garrett R. on Feb 16, 2023
Loaded 50 of these for my enfield jungle carbine. Set for shorter C.O.L .no issues.

Excellent Bullet

By Jeff T. on Jan 24, 2023
I find these bullets shoot exceptionally well in my Mosin Nagant.

Hornady .311/174 gr RN

By Steven H. on Jan 18, 2023
These tend to shoot and feed well from my No4 Mk1. While not a "tackdriver", it does place my shots within the "sticking spot" on hogs, without destroying too much meat if I do my part. I do wish however that Hornady turned these out in a .314 diameter, as I believe that is more suited to these rifles. Also on my wish list would be a 215gr RNBT. Hey, I can dream can't I?

Great bullet even better Price!

By Rudy E. on Jan 16, 2023
1/2” and 1” grouping at 100 yards with two different .303 British rifles using this bullet, very consistent and Grafs has the best price.

HORNADY 303/7.7MM(.312) 174gr BULLET

By KENNETH C. on Jan 02, 2023
Great price and fast shipping...works best in my Enfields and I WILL get more when they are back in stock....get them when you can!

Can’t be beat.

By Carl N J. on Dec 12, 2022
These bullets work great in my 1891 Arg. Mauser. Match winner at 100yds. Thanks to Graf for having this bullet available.

Excellent Service and Products from Grafs!

By Clayton B. on Dec 02, 2022
Bought these 174gr for my two SMLE's - Mk III* and No. 4 - and for my Arisaka Type 99. Only regret is that I didn't buy more as they are now out of stock! Thanks, Grafs!

Good for Mosins

By Timothy K. on Nov 11, 2022
I use these bullets for Mosins with worn, but still useable bores. The long bearing surface and flat base help stabilize the bullet in the bore. Recommend you slug the bore first, but these should work in pretty much any Russian built Mosin. Pay attention when loading Finn built rifles as many of their barrels have tight .308 bore dimensions.

Hornady 303 174 gr (.312) #3130 bullet

By James L. on Nov 11, 2022
The Hornady .312 bullet changed the performance of Number 5 Brittish Enfiled dramatically by pulling the group into the target center. My rifle is well worn and needed the upgrade to Hornady's .312 bullet. Any Enfield shooter should give serious consideration to making the change from a .311 bullet to Hornady's 3130 .312 bullet.

Perfect 7.7 Arisaka Bullet!!!

By Greg S. on Jul 30, 2020
This bullet is JUST what my rifle needed!!!! Before, I was using .311 bullets and never got better than 5 MOA accuracy. Now, 1.25 MOA is normal for me!!!

Another .303 British shooter

By Charles P. on Apr 27, 2020
These are an excellent hunting choice and match the Hornady 174gr BTHP for weight. (And both match the British MkVII service bullet weight).

Hornady 174gr RN (.312") bullets

By David A. P. on Aug 15, 2019
Couldn't find these reload bullets within 25 miles of my house, including Cabela's! Glad I found Graf & Son's, economical and fast delivery!

The best in my .303 Enfield rifle.

By Vincent m C. on May 09, 2019
These flat based long bullets give the best accuracy in my No4 Enfield rifle. Tried all the others and found they are even better than boattails at 100 to 250 yards. Best thing Grafs had them in stock when I needed them too.
