Took delivery of a .25 GK1. Tuned it for a mag (17 rounds) on a fill. Settled on 310 bar fill which produces great results. This is my second GK1 and I’ve come to see these pistols are absolutely crazy good. I’ll be trying the 25.39gr Kings, 33.95gr King Heavies and the 29.32 JTS Semi-Dom pellets. Here’s the string with the 25.39gr:

While you can achieve really good and even excellent results with some of today's precision air guns, I feel as though the slug came before the slug gun and that we are still awaiting its arrival. Perhaps there is so much money to be made trying to find the right slug, barrel, regulator pressure, hammer spring tension, barrel tension, moderator etc that producing an air gun specifically to shoot slugs properly, would be economically damaging to the sport overall. We have the ability to do so and relatively inexpensively if we want to, so why not do it? Why create this rabbit hole and the supply enough lubricant to allow any unsuspecting, would-be slug slinger to not only fall but willingly dive headlong into said sink hole? For it truely can swallow all who venture too close, even just to peer over the edge - innocently enough. By design? Say it isn't so! Is there any light at the end of this tunnel? Even a black hole has an exit as it were... .

I have 3 of their 25mm pro gauges (same as the current 28mm ones they sell) and they work very well. These are out of production. I have tried 2 of their cheaper 25mm gauges, and had quality issues with both, as I have read others did too. Until Sekhmet works out their quality problems, I cannot recommend their cheaper gauges at this time.

For now, I will just use standard analog gauges...

Sounds like I'm in the ballpark of your numbers as well. I also shoot the 25 gr and try to be around 900 on it. My first stage is at 150 and second 110. So if I do this does this techincially mean I'm tuned?

One thing I notice is that my fps still vary sometimes as high at 25 fps apart, that seems like a bad sign.

I was tempted by the Gamo Arrow based on mildly positive reviews, or nothing very negative, hoping it will be close enough to the Gamo Urban.
It is far less accurate than the Gamo Urban, with a build on par with a Crosman/Daisy multipump.

When I opened up the receiver I was horrified.
I have never seen a PCP so cheaply made (maybe because I did not buy the Benjamin Wildfire).

Gamo, as usual, managed to add their signature CAT plastic trigger and Whisper Fusion moderator.
It is a Whisper if you are deaf enough.

Gamo marketing in high gear, since Gamo is much better at marketing than actually making good air guns.
