Umarex  My Notos first impressions

Best example yet.

Shot him about 10min ago. Entered his right nostril. Was a large bump above his ass on his back. Was the slug. I removed it... Here.....

Siiiiiick! So it traveled a good 4.5-5 inches after smashing bone and stopped under the skin.

AEA  95 Caliber Zeus

AEA GUNS HAVE ENOUGH POWER.

They need to ditch their focus from more and more power.
To better customer service and better quality control.

Their ungodly thirst for power will get this whole industry severely regulated by the government. Sooner rather than later.🥲
Maybe that's the plan.

Effect of altitude and temperature on pellet speed

Long story short, been trying to finalize my TX200 setup for the WFTF Worlds in few weeks

Ran 50 shots of 8.64 pellets over the chrony giving 780 fps avg @55 degrees F, yielding 11.68 ft lbs. Shot that string at 4500 ft ASL

Now I'm a bit panicked.

Phoenix is at 1086 ft ASL, Im at 4500 ft. The usual number given for Springers at different altitudes is 1.5% change for every 1000 ft gained or lost. So in my case that a 5.2% increase in efficency going to the lower altitude. Strelok Pro also says I can expect 3.7% change in every 15 degrees of temp--but it doesn say if thats an increase or decrease. Checked for the average Novemember temp in Phoenix. 75ish degrees. Rounding off for easier math., thats 7.4% change based on 55 to 80 degrees change.

One thing I cant calculate is the effect of air drag in the thicker air at the lower altitude.

And really not wanting to switch to a heavier pellet this close to the match......

If it were any other match, Id just beg out and not go. But this is most likely the only Worlds match I'll ever attend, and Ive paid for everything except gas already. Dont want to get there and be over the 12 ftlbs before even starting to sight in......

My questions are.... Am I over thinking it? meaning, the math will work out and i'll still be legal. If not, then what are some options to keep it legal at the speeds and altitude I think the gun will be performing in?



much thanx in advance

Reliable Site to Buy Umarex Notos

I'm not sure what the policies are on this forum but I don't see a mechanism for me to send PMs. It's my first day ;)

I joined the forum today because of another post about a notos 'subscriber' moderator by tango sierra, as I have been interested in the notos for some time but hesitated as I prefer to stick with 25cal pellets/slugs if possible.

I also was looking at getting a Snowpeak M60B from Krale but they don't have the 25cal available.

Seeing that compact Zelos intrigued me, so I posted here first! Compact Snowpeak/Umarex 25cal bullpup would be ideal!
I have read that it requires 10 posts for a user to achieve PM capability, so I am posting 🙂

HILL EC-3000 POS

I bought their 2nd filter directly from Hill as well as the 50 hour maintenance kit. They were prompt and professional. For the EC-3000, they have always said that it was for filling up rifles and that's what I use mine for. Apparently the newer EVO model will top off tanks according to their literature.
Thanks , Im talking with the factory now. I will post what they decide to do. My pump is gushing air from the bleed screw at around 195 bar.

Ever have a tank split while filling

The thickness of the aluminum liner in those tanks is thinner to save weight, the Aramid or carbon fiber wrap is to supplement the reduced hull thickness sacrifice for weight saving measures. 6063 and 7075 aluminum can and do routinely hold these pressures.
Yep, a typical 80 cubic ft aluminum scuba tank has a wall thickness of .562” to .625”, and is 3,000psi fill pressure. High pressure (3,300psi) aluminum scuba tanks are even thicker. I’ve cut many 3,000psi scuba tanks to make into lamps and know the wall thickness because I measured them.

Indiana Airgun Show April 12, 2025

Hello All,

Things are gelling together and this going to happen! The inaugural Indiana Airgun Show will be held at the Boone County Fairgrounds on April 12, 2025. I've secured a 6,000 sq. ft. event hall that can accommodate 80+ tables.

The Boone County Fairgrounds are located just off the I-65 about 20 minutes north of Indianapolis. There are several hotels and restaurants within a few minutes of the fairgrounds.

more info can be found here:

I Just sent a request for 3 table. Any Left handed folks attending will be pleased, I’m thinning my collection down, going be selling a lot nice guns .

N/A  Any high end pumpers around?

This one came up for sale early this year. Maybe late last year. Probably an estate gun. There were many really nice guns at the time. I missed a couple that some other members picked up.
That is probably the nicest pumper I have seen. Reminds me of some of the old Sheridan A in quality standards.

Wonderful YouTube channel on airgun performance and accuracy

1 The Magnus, which I have already touched on.
2 Talking about the spin giving stability, there is more to pellet stability than just the spin.
3 Pellet lead is really too soft to wear out a barrel.
4 The spin stability will change the trajectory, both laterally and vertically.
5 Even without spin, a pellet will normally remain stable over long ranges, it is just not very accurate. This is why all aerodynamically stable ballistic projectiles are given some spin, to aid dispersion, not for stability.
6 The pellet is not affected by the rifling grooves after leaving the barrel. It is affected by the spin imparted by the rifling, which has a negative effect on the growth of yaw wave lengths and in spin drift, but the spin drift is caused by the gyroscopic yaw of repose and nothing to do with Magnus.
Each thing is minor on its own but taken as a whole they all build up to give a fake impression of how things work which take a lot of effort to put straight by other means.

This video is better than the one on BC's where even the basic equation for working out a BC is wrong. Both videos look like a random collection of information from various sources on the internet put together by AI or humans who don't know much, if anything, about the subject. It is a complex subject which is difficult to explain in simple terms, but that is not really an excuse for incorrect information in a video which is supposed to educate new shooters.

Umarex  Notos Accuracy

I guess you never heard of fx guns? Fx guns use what they called a liner. It is basically the barrel. They called it a liner cause it slides into a aluminum tube. The stock barrel on the notos is a standard barrel. The fx barrel kit from eBay seller that you are talking about. He sells you the aluminum tube. It has the same thickness as the notos barrel. So it goes into your gun like the stock barrel. But the kit doesn't have the actual barrel inside. That is why you need to buy the fx liner from fx. It's about $110. So basically you will need to buy the fx liner. Either 380mm or 500mm. Whatever barrel kit length from ebay you buy, you also have to buy the same length liner.

Okay I see now - I might just cancel that Terminador order then & opt for this and a 380mm shroud kit I'd mentioned earlier - winds up being about $120 cheaper that way - I don't know how much the "dampening rings" play a part, probably not worth $120 difference I'd guess. I appreciate your time and helping me understand this side of things with the detail. Once I get a good grip on the basics I can usually figure things out from there. More on this stuff is just simply where to find things, a lot of dealers I'd never heard of & not just easy Amazon finds. I'll get these mods in the works & pass along the updates - I'm sure I'll have more questions too. Thanks!
