Barrel whip and a suppressor

So I saw this video on youtube of a Romainian PSL being fired in slow motion and noticed a good bit of barrel whip.

That got me thinking of putting my suppressor on my PSL. My stamp is not back yet but when it comes in Id like to use it on my PSL but I am worried about baffle strikes if the barrel whips the suppressor out of the baffles tolerances.

Thoughts?.....

I've never heard of barrel whip causing a baffle strick, but anything is possible.

If you look closely you will see the muzzle blast as the barrel starts moving around. The bullet has already left the gun before you start getting the extreme movement you are seeing.

The barrel whip happens due to the mass of the recoil system. No barrel bowing happens until after the bullet has already left the gun. Keep in mind, however, that adding a suppressor involves removing the very fine muzzle brake that's already on the gun. The muzzle brake takes a lot out of the barrel bowing by providing straight-line force which helps keep the barrel straight. This could lead, in time, to accelerated wear and loss of accuracy. It will also result in drastically increased felt recoil. Even the best suppressor is not going to reduce recoil as well as a dedicated brake.

aside...
The shooter in that video takes the scope to the eye on every shot. You can see the scope flexing, and as the rifle recoils toward him, the scope hits him in the face every time.
Okay, back to the subject...

There's a large rubber buffer on the back of the scope that flexes back toward the shooter without issue. It only LOOKS like he's getting clobbered.

Funny, every single gun I have shot with a suppressor has less felt recoil, not more. Suppressor are very effective muzzle breaks.

This could lead, in time, to accelerated wear and loss of accuracy.

What exactly is going to wear faster with the suppressor that isn't wearing with the brake??

As for the accuracy, modern suppressors don't affect it. You will have some shifts in point of impact, but if the gun shoots MOA before the suppressor, it is going to shoot MOA after the suppressor is on it.

What I'm basically saying is that, while a suppressor may be an effective brake, it probably won't be nearly as effective as a dedicated muzzle brake. Because the brake provides straightline force to reduce barrel bowing, reducing the brake performance may lead to increased bowing, which will in turn cause increased rate of metal fatigue and loss of rigidity over time. The increased bowing may also loosen fittings around the barrel, further reducing accuracy.

That's actually how the scopes on those rifles are designed. The black piece is flexible/collapsible rubber. I've never actually fired one so I'm not sure what the point is--maybe it cuts down on glare?

The shooter is not "taking one to the eye" That scope is actually about 3" in front of his eye. The black rubber eye piecce is about 4" inches long. All PSLs come with that scope and eyepiece.

My .260 has a 26" medium Palma contour barrel. When I shoot it suppressed, some observers have claimed they can see the barrel whip. I am skeptical. However, accuracy and baffle strikes are not problems.
