Point-of-impact shift is one of the most common — and most overlooked — things that happens when you add a suppressor to your rifle. Here’s what causes it, how big the difference really is, and what you must do before you hunt.
WHAT WE FOUND AT THE RANGE: WITH VS WITHOUT A SUPPRESSOR
On our 300-metre range, we fired two shots with a Stalon suppressor and two without — same rifle, same ammunition (Hornady 168gr ELD Match .308 Win), same distance.
WHY A SILENCER SHIFTS YOUR POINT OF IMPACT
Two things are at play. First, the suppressor adds weight to the muzzle end of the barrel. That changes how the barrel vibrates at the moment of the shot — and barrel harmonics directly affect where the bullet exits.
Second, the bullet passes through the suppressor body after leaving the muzzle. That additional interaction can introduce a small but consistent deflection.
Both effects are predictable and consistent. Zero your rifle with the suppressor installed, and it will group there every time. The issue only arises if you switch between suppressed and unsuppressed without checking.
WHAT THIS MEANS WHEN YOU HUNT
A 6–7 cm shift might not matter on a moose at 80 metres. But on a roe deer — or a game bird — that margin can be the difference between a clean hit and a miss. Or worse, a wounded animal.
The rule is simple: always zero with the configuration you intend to hunt with. If you hunt both suppressed and unsuppressed, you need to know both zero points.
HOW TO ZERO CORRECTLY WITH A SUPPRESSOR INSTALLED
Remove the bolt and use a reference point 20 metres ahead to roughly align your scope and barrel. Then fire two shots and verify the group. Adjust, fire two more, and confirm. Always let the suppressor cool between strings — mirage through the scope appears faster when a suppressor is fitted, and a heat shimmer can cost you a clean sight picture.
Zero with the silencer on. Hunt with the silencer on. Simple.
