FX  Impact barrel lengths

Digging further and further into this deep rabbit hole of airgun theory, I was wondering what the more experienced airgunners think about barrel length.
My (very limited) understanding is that longer lengths help with air usage (less pressure needed to achieve a given velocity), and help push heavy projectiles at faster velocity (there is a longer runway for the projectile). BUT, this doesn't mean more accuracy, since a longer barrel is also more susceptible to whip.
Is the above correct? If so, how does one balance the pros and cons of the longer barrels?

Swarm magnum gen 3

I have a swarm magnum gen 3 and it has killed every scope I've put on it. 4 to be exact. So I'm going to make the jump to pcp air guns. I got on the classifieds section to look for a good used one but have to have posted 10 times and had 10 days of activity. So here's my 1st post. Seems like a great resource for information.

One more with the TX yesterday!

Was middle 70s here in Michigan yesterday 😁
Critters were out but only got one decent shot on a tree rat! 39 yards rested on a tree. Shooting single die Benjamin domes in 14.3 grain .One spot sitting in a big log jam just off the river bank I must have shot half dozen chipmunks but wasn't worth digging them out. Lol

Rookie Mistakes?

What are some of your airgun rookie mistakes that you learned from? For example, I learned that you get what you pay for. If you are into quality, then don't get the gun that comes in a box on isle 7 next to the gym shorts at Big Five and put a $20 scope on it expecting it to last. I also learned that stores like Wallymart, Big 5, etc. do not sell a high quality ammo and that my cheap airgun with cheap ammo explains a lot about why I made those lousy groups and missed shots on pests. It would be both fun and educamational to read some of your experiences from when you were a newbie.

What is with the FX chrono V2 ?

My friend got one of these, and TBH i am stomped.

It will extremely often miss a shot / several shots in a row completely.
It will some times ( like 1 in every 5 shots ) list a speed for a shot at least 1/4 of the actual speed of 970 FPS
And it have a couple of times barked out a speed of over 3000 FPS

I think my friend is lucky the used chrono are just from December and he got at a very low price, which seem to be for good reason

The damn thing are of course fully charged and fully updated ( with the extended sleep update FW )

Needless to say my old FX pocket chrono on his rifle perform as it should.

Brocock/BRK  Brocock Sniper HR .25 got a Power Tune from AOA

With some help from @Sleeve28 I had been trying to tune my Sniper HR to get some more FPS and FT-LB out of it, I also had reached out to AOA to get advice from them as well.
I managed to get it up to 901 FPS with 61.3 FT-LB with a 33.95 JSB pellet. I was also looking at maybe trading in the gun for the new 30 cal. Sonoran as they do a power tune that includes a new bottle and really jumps up the speed and FT-LB on that gun, then I thought why can't the power tune be done on my 25 cal. so I called AOA and talked to Shane in the service department and he said they had done a shop .25 and it was shooting a solid 960 to 970 ay 68 to 70 FT-LB, I asked about doing my gun and he said to send it down, so I took it apart and sent the action with the gauges to them and they got it shooting the same vas the shop gun and sent it back to me. Today I went and shot it and was getting 944.2 average after 33 shots with and average of 69.1 FT-LB, I was happy with that! I live in Washinton so guessing the difference from Arizona to here would affect the speed a little.
So if you own a Sniper HR in .22 or .25 and you want some better performance you should call Shane at AOA and get the Power Tune done!
I had a 700 CC bottle already and was into to it for $212! including shipping both ways.
Out of the box I was getting on the crono on with the dial on high power I was getting 862.7 FPS and 56.2 FT-LB with the 33.95 Pellet.
Next thing that I am waiting for is SUB-MOA to build a .25 cal. barrel, Shane called, and they told him 6 to 9 months and they should be making some!!

Happy shooting

Kalibrgun  Cricket : Sudden velocity increase

Dear Mates,
I am unable to resolve the issue in my Gen I Cricket. Last month I had tuned it for JSB 25.39 Kings @ 920 Fps with Rgg pressure at 132 bar. Since then, would have fired 12 shots at two different occasions as I and taken the gun to a different location around 14 hours drive two weeks back.

Day before yesterday, I saw the guage on plenum showing 125 bar reg pressure instead of set 132/133 bar.
Therefore, to see the difference on fps, I just chronographed again yesterday. Now is the mystery....
First shot was at 935fps and second shot was at 974 fps.....
I had to loosen (anti cw) the HST, step by step, test... and finally by one half circle and 1/8 more, now the avg fps is 930 fps.


I refilled the rifle, the regulator pressure on guage is 125 bar.

Guage may have some issue....But, how did the velocity increase by itself. I am not able to understand .... I request if the Cricket owners/ experts can please share the feasible reason.

Warm Regards

When Life Gives You Lemons?

Been having issues at work with a particular boss above me and had a discussion through HR about it. Cut to today when said boss above me fires me. Anyway on a random note... I had a lot of spare time suddenly so decided to do some pellet testing with all sorts of weights at 50 yards. Shot some JSB Deep 25.4 (top left?), FX 25.4 (top right?), JSB 20.1(bottom left?) and AEA 21.9(bottom right?) As well as got some sweet shots on some pest birds that I've had my eye on while the airgun has been getting a tune up. Couldn't sleep so decided to download old premier pro and see if I could try my hand at some video editing since I haven't touched an adobe product since highschool. Anyway... This is what I came up with. Will upload groupings of the pellets at 50yds later with labels along with chronograph data once I sort through it all but for now this is all I got in me for today. This all coming out of my FX Maverick .22, 500mm barrel, at 120 bar, 6mm 12gram hammer, PW 7, preload screw at about 6mm out

Hello,

New to the site. Had BB pistols and rifles as long as I can remember. I have a Gamo .177 Hunter with a BSA scope. Break barrel 1000 fps. Still works great after 20 + years. Recently bought a 17 hmr to reach out and touch ground squirrels at 100 yards…beautiful rifle but just too loud for taking multiple shots. The Gamo is only good if I’m on top of the Squirrels at close range.

I just recently discovered the world of PCP and have been really considering the Gauntlet SL series. I like the design and look and prices. I understand the .30 cal is just as loud even with a moderator as .22?

I can’t find any good reviews on the .25 and if it could take a ground squirrel at 100 yards and what would the sound be like with a moderator or even without a moderator?

I like the way I see the Gauntlet .30 hits and I’ve seen enough to think I could want to buy one but I’m afraid it’s going to be just as loud as my .17hmr?

Looking for all of your experiences and wisdom on this subject!


Thank you!
Brian

Umarex  2 questions for Umarex

Question 1: Who in their infinite wisdom designed the Notos magazine, AEA or USAID?

Question 2: Was a public apology made? If so, I missed it.

All seriousness, the rifle is great for the $ but that magazine system is a tad bit less than to be desired. It’s like using braille to load that sucker-no offense to those impaired. Those who Notos, knows…
