Does pellet choice influence loudness?
There could be a research project hidden in here somewhere ....

You're getting there with this one Phil.

Steyrs are indeed regulated, and yes they are loud, but a different sort of loud to some rifles.

I have a couple of "very well set up" regulated Ultras here. These Ultras, shot without a silencer produce a very different sort of "noise" to my Steyr LG110.
The "crack" from the Steyr is higher pitched, cleaner, and of less duration than that of the Ultras.
In this, shot side by side, unsilenced, the Ultra seems noisier.
I'd say the Steyr is actually louder in decibels, but it doesn't seem so.

To put this in perspective, if I shot my Ultra (unslienced) in the field, all the rabbits within about 500 yards would be gone.
The noise from the Steyr, does not have the same effect. As it's higher pitched and "cleaner", it seems to spook the rabbits less. Sort of like they cannot pinpoint where the noise comes from. A bit like a HMR in this respect
