Thank you Ron and Scott for setting things up.

It’s local to me, so I plan to be there.

I got this one from Arthur E Brown company years ago for my Cayman. Still on there still works great. I think I had to shorten the screws a bit.

I am using Royal Purple compressor oil. I used distilled water in my Yung Hang and it lasted 4 years, so I am using that plus a coolant . I located my water tank on the same level as the compressor. I heard that the thing that wears out these little pumps is having to push the water up 36 inches from the floor to the compressor ir it is on a table or bench.

I was using Royal Purple compressor oil , but after doing research on the oil
I learned that it is not a breathing oil like the Seco , plus the seco has a 150 viscosity over the 100 of RP. It is also a very clean clear oil , and does not leave carbon deposits. I did a forum post called Royal Purple Ice advice where the that , and the oils are dissuced in depth. I filled a 8.6 liter , and the highest temp I reached was 120°F.

Congratulations, that should do it!

Welcome to AGN. I’ve learned a lot about airgun shooting and how far it’s come since I was kid. Lots of good people here. I’m going to be a bit contrary and say that I wouldn’t use an airgun to shoot coyotes. Strictly my opinion and many will disagree but if I’m going to shoot an animal I want it going down instantly and not running away to die a slow death. I feel confident that will happen with a good centerfire but not confident enough for an air rifle at a distance of more than about 30-40 yards. For me a 30/30, .308, .270, something like that is my go to for dealing with anything bigger than a raccoon. It looks like you have some excellent rifles there, enjoy.

Fair points and I do agree with only taking ethical shots. I usually go with a buddy one of us on long range with a 243 or a 6.5 creed, the other on short range which would be with an air rifle, shotgun, or 9 mm carbine. going solo with only a pcp would be closer range only.

That is for sure a option, was shooting pellets which will chamber fine even if there is several, and we was chatting as our shot shed is a very friendly place.

Correct to both of you.
I spend hundreds of NSA slugs, 43-55gn trying all kind of speeds with absolutely zero luck, 2-3 slugs will go in one hole at 40 yards then rest are flyers, I had zero luck with NSA slugs, have not tried hybrids.
I figure I'll just stick to pellets, 44-50 JSB worked well in 850-870, FX pellets not doing good ether.

I thought maybe new 1:40 liner can be more forgiving.

I worked in 10FPS increments, but again, it takes hundreds of pellets figuring this out.

Thank s for feedback.

if anyone else have any feedback, please post.
Thank you all

Insure it to the full amount. Shipping prices are pretty nuts at times but might save you incase its "lost". I am probably selling my setup soon to get a larger bore, With powder / airguns unless im buying from a major online supplier I deal with people in person only.

I do not think so,I have 2 of their stocks and this is different;actually I bought this off eBay when a Californian could do it.When I saw it and it being a left handed stock,that is why I bought,as I knew HW77 are a good springer.
Thank you all.

I’ve never met an air gunner who has stuck to a budget so if you do!! Hats off. It’s an easy hobby to lose yourself to. CV LIFE is good entry but a cheaper Night vision say vision might be the way to go….. soon enough you’ll be shooting in the dark more than the light

Click to expand...

Well I’m already over budget on this gun haha and there’s still many things I want to do to it. The most important will be porting the block but I can do that by myself. Since this is my first PCP I’ll never get rid of it for sentimental purposes. It’ll eventually be a $450 gun with like 2k-3k put into it haha. I may have gotten lucky with the quality control gods cuz the thing is a dream to shoot… or I have low standards from lack of experience. Either way im happy haha.

I already do shoot a lot at night! I don’t bother trying to call coyotes around here during the day. It 100% can be done but these Utah dogs a very educated. I hunt them at night because I gives me way more of advantage. I don’t have an efficient way to change scopes out like @PumaCarl so I’m throwing money at the problem instead haha… looking for a day/night scope that looks good, records and gives me about magnification to shoot out to about 150yards. Hopefully the Zulus is the answer to that cuz it’ll be here tomorrow haha.

Anyone out there own a challenger 51 standard?and if so what's the best velocity specs you got ,straight out of the box no mods I've seen 630 fpe at 940 fps. Anyone else get around that ,or better? Or worse ? Lol .like to hear ur thoughts

I use 2 off them 22 n 25 lucky they arrived like that 22 hole is smaller than the 25 for some reason no incerts no baffles just a good old 3/8 cpvc tubing drill up n wrap with your favorite material.. no pics permited

it is the Diana pistol way of correcting manufacturing, lets say errors

glad it is working for you

Hn 40gr .218 slugs on my 700mm m4 I had it on had it at 170 bar shooting high speed 960-980 but drop it down to 150 bar and it's has better groups at 940-960fps...and liked better grouping on .218 38gr at 930-950fps.

But still will keep doing tunes...

.217 at high speed didn't make good groups for me

I installed Huma hammer spring but makes to much power on low settings micro at 1-4 and makes a lot.

Click to expand...

I have tried .218 and .217 at different speeds but this is what the worked best for me, i have a 800mm tensioned barrel and tried more than 10 heavy liners in 1:16 and 1:18 twistrate.
The best for me was a 1:16 twistrate.

And yes 1-4 on micro settings makes a lot but turnig on hammer valve return spring makes also a lot.

I watched your review, I thought it was good. I am pretty sure it is made by SPA and may share many parts with my P35s. The tube looking tool is to remove the pressure gauge on the end of the airtube. You pull out the nut the gauge is on to change the regulator, I think (usually comes with the gauge). Or you can go in through the other end.

That would be awesome!

Well I brought out the chronographs started playing with the Reg and hammer spring. now I can't shoot a 5" group at 50 yards. The crazy thing is the velocity is very uniform but bullets are scattered. I went up and down from about 980 down to 825. Like a dummy.I never chronographed before.I screwed with it. I ran a couple of swaps through the boar and everything seemed clean.

lol… The Tex Rex .510 is putting out numbers I’ve only seen out of my personal build. That’s why I’ve been communicating with the manufacturer over the last two days. I’m trying to get my hands on the .457 for a new build that’s been on the drawing board for nearly six months. Unfortunately, there is no release date, or any other information available on when, or if, the .457 Tex Rex will be built.

457 prototype testing is underway now at Airforce with plans to release at Shot Show in 2026 with production shortly after. when offering a lifetime warranty they need to test every design well so that they don’t get a lot of repair issues…

I paid less for my 300s, and my two Diana75s than what a new TX200 costs. One I had resealed, two I had trigger work done. Still cheaper. As much as I love my TX200 I got a much better deal on the 3 I mention. Price was not a big issue, I wanted the accuracy they offered and the precision built into them. My LGU was the same price as a new TX and is overall a more solid feeling instrument, so I was fine with the price. Chances to buy these guns don't come along everyday. If You enjoy the sport the price will be woth it.

Hey Everyone!

So I did something kind of stupid and had to tear my Notos down. I have some questions

• When i removed the air tube I noticed there were bubbles (see pic), should this be a concern? I removed the regulator and the air tube seemed dry, just lubed.
• There is a lot of oil/lube on this thing, should I wipe it off and reapply? If yes what kind of lube/oil should I use?
• I was attempting to turn down the regulator while I had it out to get more shots. The nut holding the adjustment screw in place seem really really tight, is that normal? Should I just try to man handle it to break it lose?
• While I have it apart, is there any maintenance I should do or clean up? I don't really need more power, and this thing is only 2 weeks old brand new...

Also noticed that one of the barrel o rings are nicked, so might as well order a c88 plenum kit to get more air and a thread on this thing since I destroyed the moderator...

Thank you in advanced!

Similar but different.
I used to belong to the Varmint Hunter’s Association. The monthly rag would print photos of shots on prairie dogs taken from allegedly extreme ranges. 600, 800, 1000, etc., and, in one exaggerated claim, 2700 yards on a windless day in southern Nevada…
While I would never call someone a liar on a public forum, I do consider myself a very serious rifleman even at the advanced age of soon to be 80. I have shot prairie dogs at 400-500 yards in Wyoming with my trusty .22-250. Never, and I mean never at those ranges was there a first shot hit. I have a theory about some of these long range hits on prairie rats:

Lou and Chuck are patrolling the prairie dog country and spot a likely town. They place an orange traffic cone in the middle of it and retreat to hillside 600-1000 yards away and start blasting at the cone. After a couple hundred rounds (none of which has hit the cone, btw) they drive back and see if any dogs accidentally stood in front of a speeding bullet. If they find one, a photo and story is produced!

Here on this forum a good friend of mine says he routinely splits playing cards at 200 yards with his air rifle. You and I both know he cannot even see a playing card on edge at 200 yards, regardless of the scope used. What he has is the playing seated on edge placed in front of a large black circle within which he places his crosshairs. Every now and then he strikes a card..

So, have your discussions but remember we take it all with a grain (maybe a few grains) of salt!

I like the CR better than the Diana because I don't care for the moderator. I bought one NIB (Mrodair) in an auction for $100 and never opened the package. I know I'm gonna like it. Just haven't.
I kinda like the 99 but not sure. Is it a Savage 99 replica with a hammer?

Does anybody know a reliable place in Europe where they repair airguns? My Meg leaks, and I can't stop it. :C

It’s Pelletfest at my sisters today. Whole family shooting. Lo and behold the only gun to fail, a FX. A frustrated shooter caused me to do a chronograph check. Then the gauges confirmed blown reg. Gun is following bottle pressure. It’s PCP life. Always have backup guns and air sources if you can.
