Anyone own the .177 GK1?
Didn’t help i had other issues going on .. that are now fixed. At the same time i had bought and swapped over the .177 conversion.
already had a bunch of pellets and slugs i wanted to use. Firstly .. slugs are absolutely out of the question. Way too loose in the mag. Bought and tried the NSA .178’s and still loose. I actually had one fall backwards into the valve space which Jammed it and destroyed the plastic cover .. good thing it was a replacement part in the bag. Really good think it didn’t damage the NEW valve and seats i just replaced.
As far as shooting the GK1, no matter what power its set as it dips a little in FPS but then raises. Cant shoot much over 20 mpa before it dumps air. I did try and measure the barrel using pin gauges. A -.176 will pass. -.177 will not. The mag a -.188 just enters the loading side tapering down to . -.179.
Mag is definitely too bag. Not sure what the barrel diameter in relation to cal/pellet size is supposed to be ? Just wondering if anyones had better luck with the .177.
22 is back in and shooting great.

Yes, the fill above about 250 bar is not linear . . . does that justify calling it a "waste of time?"

For most of us, we are not wasting much time in filling our tanks rated to 300 bar up to that level - yes, the fill time is less efficient than ideal, but we still get a lot more fills out of the added air and that is a good deal to most of us. We keep doing it, so it must be worth the trade off . . .

By your logic, since vehicles use much more fuel per mile driven at 70-80 mph than at 55-60 mph, nobody should be willing to ever drive faster than 55 or so. But clearly that does not match what we experience out there, so the trade off must be worth it to most of those drivers . . .

Real life.

1. Charging a supply air tank to > 250 bar is a waste of time:

200 or 300 bar? - International Diving Federation

Are cylinders that are filled to 300 bar a better solution than the standard 200 bar? This article will try to answer this question.

idf-global.com

2. For the maximum usable volume from any size supply air tank you must minimize system losses:

a. Temperature losses during supply tank charging - cool the supply tank in a refrigerator before charging, to counter compression temperature increase and subsequent pressure decrease as tank cools.

b. Maintain the volume of bleed air to fill tank volume as low as possible.

3. Two small air supply tanks fit in my refrigerator, my one large one does not.

Nice shooting! The akela doesn't like HN slugs from what I have found, NSA would cut your groups in half and so would VK slugs! My best groups with them has been .5" at 50yds for 7 shots with wind, not sure how fast though. Griffins are also really good, particularly the 13gr and 16gr

I think it's the opposite. Don't say it a crappy app just because a feature is missing. Yes, you do have to delete sessions one at a time. Part of the rationale is so you don't delete an important session. Many, many apps take this same approach.

I don't know how you can get an app that is a lot simpler to use and still provide all the data, WITH the added option to export it to your computer so you can do whatever you like with it.

I also don't know how a company, of any kind, can make an app that suits everyone.

I do think they will disappear. Not today or tomorrow, but in the future. Every year the camera sensors get better and better, just like in the photo SLR world, where digitals have taken over. Soon, if not already, someone will introduce a scope that is simply a video camera. Wait! They're already doing it in day/night scopes, but no one has gone to just a video camera for a scope. Look how small the camera in your pone is and how it's advanced over time. Now take that same technology and apply it to a scope. No more parallax problems, autofocus, the list is endless of the benefits. It'll come one day.

I think it would have already caught on if makers had stuck to a digital day scope only and not worried about night vision right off the bat. We'll get there, one day.
