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.

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 . . .

I put what I think will be the final application of Tung oil on my old Freeland wooden palm rests this morning. They are now outside baking in the sun and it looks like I finally got the end grain portions sealed as they are shining like the other areas.

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

thanks, the akela is surprisingly accurate with a good amount of shots available after springs are cut per @EPG recommendation. i’ll have to try the nsa next time. i’m still wary of ordering nsa since this debacle

having to pick all these slivers off the slugs tips is no bueno.. this is from only one box of 300 slugs. 17.5gr from AOA.

Stay in the air conditioned house and wish we could enjoy some of the outdoor activities. When outdoors here shade is the gold standard for any activity and for parking cars. Honestly even though we do get some cold weather, I use the a/c in the car 12 months out of the year, and this time of year always crack windows when parked and put one of those reflector shades inside the front windshield, they do wonders for keeping it cooler.

I don't think they are worth it. I use Huggett, DonnyFL, FX, 0db, etc and all of them quiet my guns down amazingly well and some are tuned pretty hot. They look good, work good, so what does an expensive moderator do for me?

It could be two things , first , most gauges do not agree with each other , also when you compress air it heats and the pressure reads higher than when cool. The best way to fill a tank , especially from empty , is to do it in stages , letting the tank cool and the pressure to drop . If filling an empty tank , I always do it in several stages while letting the tank and compressor cool.

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.

That’s fair. But profiles?! Like, saving a specific rifle and ammo that you can select when starting the session (from the app)?! Those things could be included without changing the app as such. Meaning you could keep using it the way it is. Or, if someone would want to, they could save a rifle as a profile. Or save their usual (or custom) ammo to use during sessions… like, it’s not a mutually exclusive either or.

thank you, really appreciate all the help

really a nice forum

I have a CS-3 that is coming up on its 10-hour maintenance in my work room and a CS-4 with 79.9 hours on it as my main compressor.
The CS-4 fills guns and tops up bottles
Both have been trouble free
My considered opinion is that the CS-4 is far and away superior to the slower, noisier CS-3.
For me it is well worth the price differential

FWIW it is a CS-4 not a CS-4i

just my two psi

I too have a WC in 22 cal, w/600mm barrel. I use either a Huggett or DonnyFL, both are about 5" long and same diameter as the barrel. The mechanical whack of the hammer is much louder than the report of the barrel.

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.

One of the issues is display size. The resolution of CMOS sensors is millions of pixels. But you cannot display that in a tube small enough for a gun. You would require a much larger display for all of the pixels which does not work for applications like aiming in a concentrated view.

Just look at the night vision resolution.

Ok, I tried the procedure suggested in the video. You can absolutely drain the moisture and not completely de-pressurize the filter itself. It is pretty easy to do. My only concern, is it also pulls the moisture from the bottom of the pump over thru the line and out the bottom of the filter. I'll have to experiment more, but I think it's a good idea to simply let er blow and clear out as much moisture as possible. The one minute added to a fill is just not enough for me to worry about.

For the record, I DO get moisture out of the bottom of the filter, not a huge amount, but some.

The Tempest and all the other variants has the barrel above the cylinder to create a length which could correctly be handled as a pistol. It makes for a very appealing design. However, while far more appealing than any other pistol (the Crosman 150 and Abas major accepted) it has the piston moving rearward.
The original thinking was this rear moving piston would allow for easier control of the recoil, going directly into the palm of the hand. Sadly it never worked as imagined.
The recoil created a pivot point just ahead of where you grip it, causing a downward jump.

The key to dealing with this problem, is getting the pellet out of the gun as quickly as possible.
The gun operating in the pop gun phase, it requires fast start pellets. 7 grainers......that seal well.
A hobby in .177 can get out at up to 480 fps if the gun is set up right and it works.
From here, you should not fight the recoil, but go for a light hold and let the gun recoil.
Lighten the trigger using the tips I mentioned and practice with it to repeat the hold.

Ordered, thank you!

The filter shoudl be bled of moisture every time you use it.

What glue/epoxy did you use? Does it crack over time?

Yes I used epoxy. So far so good.
