Umarex  Another Notos question?

Reg would be my first diagnosis if hammer hasn't been adjusted to the max and bottomed out. Sounds like youre opening the valve and getting a giant blast.
Exactly my my thought as well. If you can tell by ear when a 2 stroke is running clean, you can learn to hear wasteful muzzle blast or hammer bounce. My circle refers to this as "tribal knowledge" and I'm Greybeard The Wise Wizard that dragged them down the rabbit hole, keeper of unexplainable tribal knowledge. But I can show it.

Taipan  Taipan SLASH Review (World's Top Semi Auto Air Rifle)

Wow, that’s last collection. I always thought watching all your videos that you would have something like 60 guns. When are you gonna do more hanging and shooting? I love those videos too.
I actually do have about 60 guns. Those were the only ones I could fit in that cabinet. I still have piles of guns in boxes. But I do sell most of them which is why I only have 60. Rick Rehm Shooter 1721 had 280 guns, 2 years ago. He probably has about 350 now. In about 3 weeks I can do another Slash video and shoot it properly at 50-100 yards.

Umarex  Another Notos question?

After mulling this over, I'm kinda leaning toward a regulator problem. Attached is some early 3-shot groups I shot at 25 yds with the JSB 15.89 gr Hades pellets. I'm kinda ruling the pellet problem out at this point.

Thanks again.

FX  What causes regulator to be same pressure as the rest of the air tube?

I recently bought a used airgun and it arrived with the regulator at the same pressure as the airtube (220bar). I was told to shoot it to see if it would straighten it out (it was very loud when fired) but it didn't fix it as suspected then it went down to ~200bar but still same pressure as the rest of the air reservoir. Is the regulator damaged in any way if this happens or is it something easily fixable?

Try using some Airgun Butter Lube on the whole regulator sold by Warren at Air Shootist. It's made exactly to possibly fix this kind of problem. Its $30.00 for 1 ounce but a little goes a long way. I've been using it for awhile and it seems to work great! 😃

Cure to the illness?

I have had my first PCP less than a week and I just ordered a GX pump, tons of pellets, and already looking to upgrade my rifle. No one warned me this was hobby was so addictive and the bunny hole is deep enough to not have a bottom.

I grew up shooting a Benjamin Sheridan many years ago and was a menace to any squirrel, rabbit or bird my entire youth. Over the last 40 years, I have shot lots of rimfires, rifles, pistols and muzzleloaders but never really thought too much about pellet rifles. Until recently.

I decided to upgrade my old sheridan to something more modern and ordered the first rifle I saw on YT that had a good review- A Gamo Urban. I knew it would get my feet wet and help me decide if this is something I want to do more seriously but had no idea what kind of addiction it was unlocking. Now I'm looking at high-end shooters that I have no business buying right now. The healthiest thing for my pocket book and marriage would be if yall ban me right now!
1 pcp? Just wait.

FX  What causes regulator to be same pressure as the rest of the air tube?

I've got three FX rifles that take the same AMP reg. I have 4 or 5 of the latest AMP reg's and 4 or 5 of the HUMA w/ all the different washer stacks. I've used all extensively. Both have pros & cons. If I had to choose.....I'd choose the latest AMP. I get just a tad better consistency. Both reg's use delrin seals, so no real difference there. Honestly you can't go wrong with either. I even use an AMP w/ the delrin piston as the 1st reg on my Wildcat and it works fine. The only real pluses of the HUMA has is the power range can be more narrow which theoretically would result in better consistency, but isn't proven in real life. Also, the replaceable delrin Disc. The answer to that is keep a spare AMP piston.

Every reg will periodically need rebuilt. I've had to rebuild both about the same amount.
I will modify my previous opinion. Any reg with a brass piston. New amp or huma. With the impossibly small holes in the pistons, id rather mess with flipable inexpensive delrin discs as the wear item than the piston itself.

I call stuff that is low effort and low expense to make "dumb parts". The delrin discs that go with the brass pistons are dumb parts, easily made which is why i like them.

AirMaks Arms  Airmaks Katran/BRK pathfinder - Airgun euphoria

I’m another CZ addicted member. But I give anything a chance to measure up. 😊

I've got enough birds down here, I can hardly keep up with the iguanas 😂.

@SMH you are now hooked on CZ for life bud 😉
There is a reason people get addicted to Cz barrels. Just pulled her out of the safe to check after sitting a day or so. 5 pellets and I had taken off the moderator. SOLID.

Umarex  Another Notos question?

Reg or hammer settings.

You can get an inexpensive 1:1 spa pp750 reg from ebay. Sometimes regs will creep during fill. Your hammer may be low in the range. But sounds like youre creeping. Your reg may be set ridiculously high because that's how unregged guns behave.


Have you screwed your hammer spring adjuster all the in/out

The first shots are they really quiet?
I have not messed with the hammer spring adjuster, but I will take a look at it. The first shots are kinda loud. It takes several shots before it settles down. I'll probable try a new reg.

Thanks for the info guys. 20PPC

GX-E-5K2 PCP Air Compressor, 5800psi

Personally, I would go with the GX-E5K2, but which Air Venturi compressor are you considering? I can tell you, all the compressors sold by Air Venturi are rebranded and made by someone else.
And the A.Venturi have difficulty sourcing the parts if something other than a seal needs replacing. Just recently went through this with an expensive Nomad 3. Now I'm SOL

AirMaks Arms  Airmaks Katran/BRK pathfinder - Airgun euphoria

Compacts! Yet to try a BRK product. Taipan Veteran, Airmaks ... CZ barrel ;). I believe there are some others AGT etc that use CZ barrels which I have not tried either. I have a past few issues with Airmaks right from the horses mouth on their end ( gave another chance cause the Katran was a wonderful intro for my wife into PCPs from springers ), but they pack some darn good features around that CZ barrel for the price/quality point. Humm, yeah, seems like my venture into this has also found some sort of pattern. SMH, thanks for the post and sharing. (y)
Definitely priced below what they actually are.

What diameter barrels for Airforce Talon and Escape in .25caliber?

Chard, I have the Airforce Escape UL with both the .22cal and the .25 cal barrels. My favorite ammo for both are interestingly the same. The .22 cal does very well with the H&N Baracuda 21 gn pellets and the Apolo 21 gn slugs. The .25 barrel does very well with the H&N Baracuda 30.89 pellets and the Apolo 33 gn slugs. The Escape UL, IMHO, is the perfect field hunting rifle... very light weight, can be power wheel adjusted in the field easily. I normally keep mine set up to shoot 10 shots per fill at ~60 ft lbs with the .25 cal barrel, from about 2300 psi down to about 1800 psi, so hand pump friendly. A few more shots are available in .22 at about 45 ft lbs, again hand pump friendly. I do have a compressor, but only use it to fill my buddy bottle that I take to the field to refill the Escape UL if necessary.

What do you have your power setting at when you’re shooting from 2300 to 1800 psi?

Taipan  Taipan Slash first tuning report.

I'll post more power curve results from my slash when I have them. The data tables I posted all ready summarize the general performance range from my Slash for a dozen pellets and slugs over a minimum to maximum regulator pressure.

I expect that direct comparisons of the Slash performance to that of other air guns will generate their own separate threads once we have some more performance results from the longer barrel models the 30 caliber models.

That's great. I owned the K1 and it's great, but as you say ..There are a bunch of threads about it and turning this thread into one of them isn't necessary IMO.

I expect that direct comparisons of the Slash performance to that of other semi auto air guns will generate their own separate discussion threads once we have some more performance results from the longer barrel 22 and 25 cal models and the new 30 caliber Slash models expected this fall.
