When you’re chasing accuracy, everything matters. The rifle, the ammunition, the optic, the shooter and yes, even the suppressor hanging off the end of the barrel.

But does a suppressor actually make a precision rimfire rifle more accurate?

That was the question behind this test.

For this Dayattherange accuracy test, seven different rimfire suppressors were put head-to-head using the same rifle, the same ammunition, and the same shooter. The goal wasn’t simply to see which suppressor was quietest. We wanted to see what happened to group size as the suppressor went from cold to warm.

And because this is Dayattherange, we weren’t satisfied with simply looking at a five-shot group.

The real test came with the 10-shot groups.

The Rifle and Optic

The test rifle was a Vudoo action paired with a 360 carbon-fiber barrel, topped with a Leupold Mark 5HD 3.3-18x scope.

The ammunition was Lapua Midas+, a premium .22 LR match load that gives us an excellent foundation for a precision accuracy test.

That is important.

When you’re comparing suppressors, you don’t want ammunition inconsistency becoming the story. The goal is to give every suppressor the same premium ammunition and let the suppressor’s performance or lack of performance show itself on paper.

And there was one more important variable.

The shooter.

Enter DM

This test was conducted by my Air Force buddy, DM.

DM doesn’t like being on camera, but he is exactly the type of shooter I want involved in an accuracy test like this. We’re not looking for somebody simply spraying rounds at paper and picking the prettiest group.

We’re looking for repeatable shooting and honest evaluation.

Each suppressor received a five-shot group with the suppressor cold, followed by a 10-shot group with the suppressor warm.

That distinction turned out to be extremely interesting.

The Test Procedure

The basic test was:

First group: Five shots with a cold suppressor.

Second group: Ten shots with a warm suppressor.

The purpose of the two-stage approach was to see whether the suppressor’s performance changed as it heated up.

Anyone who spends enough time shooting precision rifles knows that the first few shots can sometimes tell a very different story than a longer string.

A five-shot group can look fantastic.

Then shots six through ten arrive.

That’s where we find out whether we really have an accuracy performer or simply a pretty little group.

The Initial Results

Here is what the seven suppressors produced.

Suppressor	5 Shots Cold	10 Shots Warm	10 Shots Face-Off
No Suppressor	.742″	.495″	—
KGM RF22	.957″	.876″	.802″
Otter Creek Ti22	.954″	.625″	—
OSS Rad22	.478″	.841″	.746″
Dead Air Mask	.606″	.670″	.647″
SilencerCo SwitchBack	.759″	.463″	—
SilencerCo White Sparrow	.530″	.531″	—
Yankee Hill Machine Stinger	.450″	.617″	—

And this is where things get interesting.

The Cold-Suppressor Winner

If we only looked at the first five shots, the Yankee Hill Machine Stinger would take the crown with a .450-inch group.

Very close behind was the OSS Rad22 at .478 inches.

The White Sparrow produced a .530-inch group, while the Dead Air Mask came in at .606 inches.

But notice what happens when the suppressors heat up.

The leaderboard changes dramatically.

Five Shots vs. Ten Shots: The Accuracy Story Changes

The five shot cold groups are interesting, but the 10-shot warm groups tell a much more useful story.

The SilencerCo SwitchBack produced a .463-inch 10-shot group.

That is the smallest warm 10-shot group of the entire test.

That’s significant.

We aren’t talking about five carefully selected rounds.

We’re talking about ten shots.

The SilencerCo White Sparrow was right behind it at .531 inches.

And perhaps more impressively, the White Sparrow went from:

.530″ cold → .531″ warm

That’s almost exactly the same group size.

That is the kind of consistency that immediately gets my attention.

The Yankee Hill Machine Stinger also performed well with a .617-inch warm group.

Then came the Otter Creek Ti22 at .625 inches and the Dead Air Mask at .670 inches.

The OSS Rad22 is perhaps the biggest surprise.

It produced a fantastic .478-inch five-shot cold group, but the 10-shot warm group opened up to .841 inches.

That is exactly why we don’t stop at five shots.

---

The No Suppressor Baseline

One of the most important groups in this test was actually the rifle without a suppressor.

The unsuppressed rifle produced a .495-inch 10-shot group.

That gives us a baseline.

And that baseline makes the SwitchBack’s .463-inch group especially interesting.

The SwitchBack didn’t simply produce a good group compared with the other suppressors.

It produced a warm 10-shot group smaller than the rifle’s unsuppressed 10-shot baseline.

The difference is small, but that’s precisely why controlled testing matters.

We’re talking about differences measured in hundredths of an inch.

At this level, one group doesn’t prove a suppressor makes a rifle more accurate but it certainly gives us something worth investigating.

Did DM Pick the Right Three for the Face-Off?

Now comes one of my favorite parts of this test.

After looking at the initial results, DM selected three suppressors for a final face-off:

KGM RF22

OSS Rad22

Dead Air Mask

Those three were then tested again with 10-shot groups.

The results:

Suppressor	Face-Off 10-Shot Group
Dead Air Mask	.647″
OSS Rad22	.746″
KGM RF22	.802″

So did DM pick the right three?

Yes and no.

If the goal was to find the three smallest warm 10-shot groups, then the answer is clearly no.

The SwitchBack had already produced the best warm 10-shot group at .463″.

The White Sparrow produced .531″.

The Stinger produced .617″.

The Otter Creek Ti22 produced .625″.

All four had smaller initial warm 10-shot groups than the KGM RF22, OSS Rad22, or Dead Air Mask.

But that’s not necessarily a criticism of DM.

The face off was likely based on more than simply looking at the smallest number. The cold groups, behavior during the string, visual appearance of the groups, confidence in the suppressor, and what DM saw while shooting all matter.

And that’s another lesson from real-world accuracy testing:

The smallest number on a spreadsheet isn’t always the whole story.

---

And Then There Was the Dead Air Mask

The Dead Air Mask is where the face-off gets particularly interesting.

Its initial results were:

Cold: .606″

Warm: .670″

Then, in the final 10-shot face-off:

.647″

That’s remarkably consistent.

It didn’t suddenly produce a tiny .3-inch group.

But it also didn’t fall apart.

The Mask stayed in roughly the same neighborhood across the testing.

That makes it the winner of the three-suppressor face-off.

But I want to be careful with the wording.

Is the Dead Air Mask the Most Accurate Suppressor?

Not based on this complete dataset.

The most accurate face-off suppressor was the Dead Air Mask, with a .647-inch 10-shot group.

But the smallest 10-shot warm group of the entire test belonged to the SilencerCo SwitchBack at .463 inches.

And the White Sparrow’s .531-inch group is equally difficult to ignore especially because its cold and warm groups were virtually identical.

So if I were ranking the initial accuracy results, my attention would be on:

1. SilencerCo SwitchBack — .463″

The smallest 10-shot warm group in the entire test.

2. SilencerCo White Sparrow — .531″

Almost as impressive, but with something even more interesting: .530″ cold and .531″ warm.

3. Yankee Hill Machine Stinger — .617″

Strong warm performance after producing the smallest five-shot cold group.

4. Otter Creek Ti22 — .625″

Another suppressor that deserves consideration based on the 10-shot warm group.

5. Dead Air Mask — .647″

The winner of the three-suppressor face-off and one of the more consistent performers.

---

What About the OSS Rad22?

The OSS Rad22 deserves special attention.

Its first five shots measured only .478 inches.

That’s excellent.

But the 10-shot warm group opened to .841 inches.

That is a huge enough change that I would want to investigate it further.

Was it simply ammunition?

Was it shooter AirForce (ChairForce) induced?

Was there a point-of-impact or barrel harmonic change?

Did the suppressor’s temperature change the system?

Or was that .478-inch group simply one of those beautiful five-shot groups that doesn’t tell the whole story?

We don’t know yet.

And that’s exactly why I like this test.

It raises questions instead of pretending one group answers everything.

---

The White Sparrow Might Be the Sleeper

If there is one suppressor in this test that really caught my eye, it might actually be the SilencerCo White Sparrow.

Look at the numbers:

Cold: .530″

Warm: .531″

That’s about as close as you can get.

It didn’t win the smallest group.

The SwitchBack did.

But the White Sparrow demonstrated something every accuracy shooter appreciates:

consistency.

The suppressor didn’t appear to care whether it was cold or warm.

For a precision rifle, that can be more valuable than a single spectacular group.

---

What Did We Learn?

The biggest lesson from this test isn’t simply which suppressor produced the smallest group.

It’s that five shots can tell you one story while ten shots tell you another.

The OSS Rad22 is the perfect example.

A .478-inch five-shot group looks fantastic.

But the .841-inch warm 10-shot group tells us we need more data.

The Yankee Hill Stinger had the best cold five-shot group at .450 inches, but its warm 10-shot group was .617 inches.

The SwitchBack went the opposite direction, producing a .463-inch warm 10-shot group.

And the White Sparrow essentially stayed put.

That’s the kind of information I want from an accuracy test.

---

The Dayattherange Accuracy Verdict

If you forced me to pick one suppressor based strictly on the data from this test, my answer would be:

SilencerCo SwitchBack

Why?

Because it produced the smallest 10-shot warm group of the entire test: .463 inches.

And 10 shots carry considerably more weight for me than a five-shot group.

But I’m not ready to declare the SwitchBack the definitive winner based on one group.

The White Sparrow’s .530-to-.531 consistency is extremely impressive.

And the Dead Air Mask deserves credit for winning the actual face-off with a .647-inch 10-shot group.

So my current Dayattherange leaderboard would look like this:

Best 10-shot group:
🥇 SilencerCo SwitchBack — .463″

Best cold five-shot group:
🥇 Yankee Hill Machine Stinger — .450″

Best cold-to-warm consistency:
🥇 SilencerCo White Sparrow — .530″ / .531″

Face-Off Champion:
🥇 Dead Air Mask — .647″

Most interesting result:
🥇 OSS Rad22 — .478″ cold / .841″ warm

And that’s exactly why we’re going to keep testing.

The Next Question: Can We Reproduce It?

This is where I’d like to take this experiment next.

The SwitchBack’s .463-inch group is impressive.

The White Sparrow’s consistency is impressive.

The Stinger’s .450-inch cold group is impressive.

But one group doesn’t make a champion.

The next test I will be taking the challenge possibly with a few additional suppressors with the same rifle with the same Lapua Midas+ ammunition and shoot multiple 10-shot groups with each suppressor ALL ON CAMERA for your viewing pleasure.

Then we can calculate:

• Average group size
• Smallest group
• Largest group
• Extreme spread
• Average cold-to-warm change
• Point-of-impact shift
• Consistency from group to group

That’s when we can start separating a lucky group from a genuinely accurate suppressor/rifle combination.

Because here at Dayattherange, we’re not really looking for the suppressor that produces the prettiest target.

We’re looking for the suppressor that can repeat the performance.

Final Thought

A premium rifle like this Vudoo with a carbon-fiber 360 barrel, a Leupold Mark 5HD, and Lapua Midas+ ammunition gives us a pretty serious accuracy platform.

At this level, we’re chasing differences measured in hundredths of an inch.

And that’s what makes this kind of testing so much fun.

The question isn’t:

“Which suppressor shoots the smallest group?”

The better question is:

“Which suppressor can consistently shoot the smallest groups?”

That’s the test I want to answer next.

Stay tuned. The targets have more to say.

Dayattherange

Shoot. Measure. Analyze. Repeat.
