Can Frontier 77gr OTM FR262 Replace MK262? 5-Barrel Test Results

Bottom Line

Frontier FR262 delivers impressively high velocities for a 77gr load, but performance is inconsistent. Across multiple barrels and even between lots, I saw large swings in velocity SD’s and accuracy, making this a questionable choice if consistency matters.

Pros & Cons

Pros

• High velocity for a 77gr load

• Potentially good performance (with the right lot and barrel)

• Lower cost vs MK262

Cons

• Significant lot-to-lot inconsistency

• Poor velocity standard deviation in most barrels

• Frequent extreme outlier shots

• Generally underwhelming accuracy

Overview

In this test, I evaluated Frontier Cartridge 77gr OTM (FR262), a load that appears to be a budget alternative to Black Hills MK262.

At the time of testing, there was very limited information available on this ammunition, and availability was restricted to only a couple of retailers.

To build the dataset, I fired 180 rounds across five different barrels, all confirmed to meet 5.56 NATO chamber specifications (as required by Frontier for this load).

Two different lots were included in testing:

• Lot 14260066

• Lot 14260001

And as you’ll see, lot-to-lot variation turned out to be a major factor.

Test Setup

All groups are 30-shot groups at 100 yards, using the standard testing protocol:

• Front rest + rear bag

• Chronograph data recorded for all shots

• MantisX and Shooters Global SG Pulse to detect any shooter induced fliers

Barrels tested:

• Red Right Hand 20” LMG HBAR (Nitride)

• Centurion Arms MK12 18”

• BCM KD4 16”

• Hodge Defense 14.5” (2 lots tested)

• Centurion FBI 11.5” CHF/CL

Velocity Performance

Across all barrels, one thing is clear:

This ammo is fast.

Average Velocity by Barrel

• 20” – 2852 fps

• 18” – 2786 fps

• 16” – 2750 fps

• 14.5” – 2700 fps

• 11.5” – 2519 fps

This puts FR262:

• ~60 fps faster than MK262 in the 18” barrel

• ~130–240 fps faster than other common 77gr loads (IMI, Federal Gold Medal)

That’s a meaningful velocity advantage.

The Problem: Velocity Consistency

Despite the speed, consistency was poor in most cases:

• SD ranged from 20 fps (best case) to 56 fps (worst case)

• Extreme spreads reached 263 fps

• Multiple barrels showed outlier slow shots (100–200 fps below average)

This wasn’t isolated, it showed up in multiple barrels, which suggests ammo-driven inconsistency rather than barrel-specific behavior.

Accuracy & A-ZED Performance

Best to Worst A-ZED Results

• Hodge 14.5” (Lot 66): 290 yards

• BCM 16”: 229 yards

• Centurion MK12 18”: 206 yards

• Red Right Hand 20”: 172 yards

• Hodge 14.5” (Lot 01): 138 yards

• Centurion FBI 11.5”: 85 yards

Key Takeaways

• Only one standout result:

  • Hodge (Lot 14260066) delivered a strong 0.487 MR / 1.585 MOA ES / 290 A-ZED

• Most other results fell into mediocre to poor territory

• The 11.5” barrel produced:

  • Severe vertical stringing

  • One of the worst groups recorded in this dataset

Lot-to-Lot Variability

This is where things really start to fall apart.

Hodge 14.5” Comparison:

• 30-Shot Group (Lot 14260066):

  • 1.585 MOA / 290 A-ZED

• 30-Shot Group (Lot 14260001):

  • 5.036 MOA / 138 A-ZED

That’s not a small difference, that’s a completely different class of performance.

Observed Lot Differences:

• Velocity shifts (~20-50 fps difference)

• Primer appearance differences:

  • Silver vs brass-colored primers

• Significant group size divergence

This strongly suggests inconsistent loading or component variation between lots.

Barrel-by-Barrel Highlights

Red Right Hand 20”

• Fastest recorded velocity (2852 fps)

• Poor SD (46 fps) and large ES (245 fps)

• Split lot showed ~50 fps velocity shift

• 3.536 MOA / 172 A-ZED

Hodge 14.5”

• Best and worst results of the test

• Lot-dependent performance swing

• Proof that this ammo can shoot well, but doesn’t always

Centurion MK12 18”

• Frontier FR262 was faster than MK262 by ~60 fps

• Worse accuracy than MK262, IMI, and Federal

• 2.567 MOA / 206 A-ZED

BCM KD4 16”

• Decent but not impressive

• Still affected by slow-shot outliers

• 2.783 MOA / 229 A-ZED

Centurion FBI 11.5”

• Worst performance overall

• Severe vertical stringing

• Worst SD (56 fps) and ES (263 fps)

• 5.759 MOA / 85 A-ZED

Final Thoughts

Frontier FR262 is an interesting concept:
A high-velocity, lower-cost MK262-style load.

But based on this dataset, it’s not something I’d rely on for applications where consistency matters.

The biggest issue isn’t just accuracy, it’s predictability:

• Velocity variation

• Lot inconsistency

• Occasional extreme outliers

If you happen to get a good lot, it can perform well.
But that’s not a gamble most people should be making.
