Possibly a small amount if water in there would do a similar thing. Work like a cooling agent on the burning gases.

Another device to separate gullible hunters from their cash. If you’re only going to fire one shot first round pop is irrelevant as the animal is hopefully dead aye. Personally I can’t say that I notice much difference between first and subsequent shots in actual hunting situation, I’ll try and pay more attention when I go out later this arvo. Have to say that unless you’re using subsonic ammo there’s always going to be supersonic ‘crack’ anyway.

A condom placed so the closed end was slack over the muzzle (as in with your partner) held with a rubber band was most effective. And it's the column of compressed air being pushed up the barrel that severs the tape, NOT the projectile.

True and a fair point - I was trying to say that with a 308, a bit of tape makes no difference IMO on point of impact but yes it is the column of air that severs the tape

so what about the frenchy???? surely it has enough expansion room to stretch for all that air so it would be projectile that breaks through....wont matter a hoot up close

HAHAA Interesting guys taking packets or rubbers into the bush hahaa

I am reading this thread and wondering if it is the fact that water is not a rigid material and that its movement / flexibile surface stops the sound waves in the same way a soft surface works in a recording studio......

this gives the old youthful adage of "gettin a shot away" a whole new meaning.Ive heard from assorted ex Vietnam vets some yanks used the old rubber over the m16muzzle trick in the wetter junglealtho it didnt seem to make much difference.the consensus was rifle maintainence was crucial for effective operation.

I would suggest it would be much like water filled batwing bags and stonedust in u/g coal mines.
It is picked up by the blast and puts out the flame of the explosion.
And yip see little proper use for it in our circumstances unless really trying to prove a point

When the Saturn V rockets took off from the launch pad they spray water because it absorbs some of the energy of the rocket blast. Apparently without the water spray the launch pad would be wrecked.

Well, went out this arvo after some goats in regen bush.Can't say I niticed any difference in sound level between 1'st shot and next five, i don't believe any of the 5 now diceased goats did either. On the drive home I got to thinking how 4 deer in vineyard on thursday night didn't seem to notice either. So I'll just put this first round pop thing down to something target shooters are noticing, got more important things to worry about like where the next animal is and trying to stay dry.

Probaly our ears are still recovering from the first shot too much to notice the follow ups....We are paying more attention to what is out in front of the barrel than what comes out of it....(or we should be?)

It’s a dpt so I was disassembling it every night and drying it out. Every night there was a small amount of water in every baffle.
How is accuracy affected with larger amounts of water in them?
I assume they’re still safe to fire?

Tape over the end of my DPT and then an additional two loops of tape around the lower part of the suppressor (to replace if/when I shoot).

Never had water in there.

Cheers

If you go view the takeoff of Elon Musk's recent rocket (which did not have any water cooling jets employed) you can see huge chunks of concrete bouncing around everywhere. Some bounced right up and hit hydraulic lines inside the motor, some hit some solid state motors, and so in only a minute or so the rocket failed. Apparently the craters gouged into the reinforced concrete by the rocket motors were meters deep

Have always taped barrel in wet conditions and never noticed any POI change even the 222/223. I did read that it is the pressure in front of the bullet that pops the tape, but it doesn’t work the same on a suppressor as the gases fill the suppressor body and disperse more. That article recommended removing tape on suppressor before firing.

I watched a vid on YouTube recently where they tested taping the absolute fuck out of their muzzle brakes and in slow-mo it showed the air infront of the bullet blow all the tape off the muzzle brakes and had no effect on POI

I tried it and found a small bit of tape was ok on my suppressor.
