as tony has said
I was a member of a full-bore pistol club 25 years ago. Some-one brought a .22 rimfire rifle to the range. I was amazed at how quiet it was. No silencer fitted. It made much less noise than my springer rifle. Many folks on here will be aware of that but many folks might be surprised.
All about where and when the peak pressure is I suppose.

On 10m PCP’s the barrel proper is fitted inside a much longer tube. Manufacturers claimed it was advantageous for accuracy for the pellet to enter “still” air when it exited the barrel. The tube is also needed though to maintain a suitable sight radius. If you turn a drilled plastic plug with a cone on the end and insert this inside the tube it quietens them quite a bit. I made the plug from red plastic so it was easily visible. It had two O rings fitted to keep it in the barrel and the end was threaded M8 a little way so a bolt could be inserted to remove it if required.

If I don’t reply to your comments it’s probably because you’re on my Ignore list.
I fitted the plastic cone to my old Anschütz 2002 so that must have been well over 15 years ago. I think I may still have one for my P700 somewhere.
