Description
The Hornady Frontier FR420 steps up your range day with straight-shooting reliability backed by Hornady's name and decades of ammunition expertise. This load pairs military-grade components with careful quality control, making it a solid choice for anyone feeding an AK-pattern rifle or SKS.
What sets Frontier apart is its commitment to accessible quality. You're getting brass cases loaded with boxer primers and mil-spec propellant, not the steel-cased surplus stuff that can leave your rifle dirty and extraction questionable. The 123-grain FMJ bullet cycles smoothly through magazines and chambers, feeds cleanly with minimal fouling, and performs predictably downrange. Running at 2340 fps with 1495 foot-pounds of energy, you've got a balanced load that handles fast follow-ups and extended range sessions without hard recoil.
Frontier FR420 builds consistency round to round
Hornady worked with Lake City Army Ammunition Plant to load this ammunition, tapping into their expertise in military-spec production. That partnership shows in the attention to loading uniformity and primer ignition reliability. Every round meets the same standards, so you're not left guessing whether the next mag is going to perform like the first one. For anyone running high-volume training or just wanting ammo they can count on, that consistency matters.
7.62×39 brass from Hornady for serious shooters
Brass cases mean reloadability if you want to stretch your shooting dollar down the road. They also mean cleaner extraction and easier maintenance compared to steel-cased alternatives. The boxer primers and non-corrosive formulation keep your gun running clean, so post-range cleanup stays simple. Whether you're punching paper at the range, testing your rifle's accuracy, or just putting rounds downrange, you're working with ammunition built to serve your needs without complications.
Includes 20 rounds per box.

Frequently Asked Questions
Will the Hornady Frontier FR420 work in my AK-47 or SKS?
Yes. The 7.62x39mm caliber and FMJ design are fully compatible with AK-pattern rifles, SKS rifles, and any modern sporting rifle chambered for this round. The 123-grain bullet weight and reliable feeding characteristics work smoothly through standard magazines and chambers used in these platforms.
Can I reload Frontier brass cases?
Yes, Frontier cases are reloadable brass. They do have military-style primer crimps that need removal before seating new primers, but that's a straightforward process with standard decapping tools. The brass quality matches full-power Hornady loads, making them worthwhile to save and reload.
How does Frontier 7.62×39 compare to imported surplus ammo?
Frontier delivers more consistent velocities and cleaner performance than most surplus military ammo. You get non-corrosive primers, uniform powder charges, and reliable ignition in every round. The trade-off is slightly higher cost, but you're paying for predictability and easier rifle maintenance, especially during high-volume range days.
Is this ammunition suitable for hunting?
The 123-grain FMJ load is effective for varmint hunting on game under 50 pounds at moderate ranges. For larger game or situations requiring rapid expansion and deeper penetration, soft-point or hollow-point designs are better choices. For training and range work, this FMJ load delivers solid all-around performance.
