Here's and update to my GK1 .22 matrix I started in 2023 and posted a few weeks ago. All data is current and replaces any previous matrix I've posted.
I created this matrix for my own use, to quickly see what kind of power (ft-lbs), and shot count I was getting at various power levels (i.e. GK1 turns out) with various pellets. In most cases, I did a 300 bar and 250 bar fill test. The reason was if my GX Compressor E-L2 craps out, I may not always be able to fill to 300 bar.
I'm sharing because it's a lot of data, and can be useful to those of us with a GK1 .22.
For me, backyard friendly is usually anything below 81-82 decibels at 27 ft away from pistol. However, decibel ratings below 80 dB are best and I feel less nervous. Also, some days were windier than others, so dB readings can vary depending on type of weather.
