Test it out, I think thats amazing!

Hello all. One more time- thank you for opening this thread and discussion.
Encouraged by your experiences, I felt ready to go down this rabbit hole and start playing with the HS tension. Right from the start, the results are beyond any reasonable expectations.
So, here we are:

I have U2 .25 700mm, using 37gr (2.4g) Zan slugs @160bar approximately (1/4 turn CCW on regulator from factory settings).

Velocities before HS tuning were 938-946fps with approximately 40b airdrop for 1 magazine/ 10shots. That’s 4b per shot.

Encouraged by your posts, I turned my HS screw 2 1/4 turn CCW, because of that I had to dremel the stock interior for approx. 1.5mm. I fired 10 shots, then waited for 24hours, then fired another 20shots.
To my shock, on first magazine speed started at 475fps, but next day, on second and third magazine, it went all the way to 715fps. But ofc I wasn’t satisfied with that and I started to turn HS screw CW. At the end, for 3/4th of a turn. So, now my HS screw is 1 1/2 CCW opened from the factory settings.
I shot 1 magazine, then waited for 24 hours to allow the spring to adjust and then again, today, I shot 1 magazine. So…

On my last magazine, 10shots, speeds were from 920.6-926.5fps, so my ES was less than 6fps (before this tuning, usual was 8-10fps, if I remember correctly max ES was 12fps AND… now the airdrop per magazine (10shots) is approximately 15bar DAFAQ?!?

So… next thing I’ll do is to play around this setup.
My goal is to leave the regulator @160b, to find minimal tension for HS while achieving speeds from 900-1000+fps, depending on slug grains, while using minimal air pressure possible what would also be quieter than it used to be.

As for precision- I was focused on velocity/air pressure but I haven’t noticed any noticeable precision drop while doing so.

Guys, one more time big RESPECT , this was unbelievably well spotted detail in these overall fantastic airguns.

Thank you again,

S.

AJ,

thanks for your help.
It was a breeze, once I knew what I needed to do. Thanks to your instructions!

Have a great week.

Your asking to fill your gun ? look up paint ball ranges or shops , might not fill to full pressure . Or just wait a few days for your parts.

Good idea I did not think about paintball thanks!!!

I like my DRS Classic Composite 600 mm .22.

It is more accurate with pellets at ranges between 50 yards and 160 meters, than my (2) Streamlines and AA S510 Extra. That's with it driving 14.3 gr pellets at 1030 fps, about 100 fps faster than the other three.

Other than louder muzzle bark, it comes out ahead of the other three. I may buy a second identical DRS.

This topic has been brought up, but I didn't want to hijack that thread.
Some guys like poly...some guys don't.
My question is.... if a platform is robust... how important is Oring type?
I ask that question based on this video.

I just use what fits, most of my kits are nitrile but I do have green and red poly kits too. To be honest have not had any issues with the poly. Plus the colors tell me where I've worked.

I had a nitrile oring blow out last night on my Evanix Sniper X2. That was the oring between the gun & the regulator. But that interface took an 18mm bonded seal shim at the base to get the regulator to seal. Threads on the gun were too long for the regulator. Unregulated gun, so those threads expect to screw into a bottle.

I grease my orings rather than oil them which probably helps long term.

I have the ambis on one of my 777s, they work good enough to satisfy my left handed shooting desires. Off hand one handed at combat speed I trust my left hand more than my right hand, but for target shooting slow fire I still like to match my eye dominance with my hand dominance. I'm trying to see if I can enjoy that slow careful pace with my left hand. When I get frustrated I can shoot two handed either hand leading with those wood grips you highlighted.

When you take your 777 grips off look carefully at the pin that is protruding into the OEM grip and make sure your new grip will accommodate it. If not carefully drill or Dremel.

Great guns!

This, and it’s even worse putting on an AR-styled rifle as it’s the reverse of the ambi-selectors I have on my rifles. It goes beyond an annoyance because it creates a legitimate concern when using my air rifle; I’ve had instances where I’ve had the rifle on fire thinking it’s safe, missed shot opportunities because the safety was on, etc… I actually ordered an M2 selector to put in my M3 for this very reason, and will be pinging FX to see if they can manufacture a non-goofy one for the DRS. Before someone calls out the receiver markings, I’ve got tape over my M3 and will be getting an overlay made from Gunskins with a pictogram to match the standard selector pattern.

That said I love this thing…

Already missing it…

I kinda like the silver satin, it'd be easier to see when searching for a magazine in an ammo box in dim light.

My favorite caliber is .22 for hunting, pesting, target shooting and N50 competition. I do have a couple .30s for 100Y Benchrest matches but I don’t shoot them nearly as often as I do my .22’s.

Interesting, I thought that was just a Southern thing?

Not at all, our diking district has a guy that shoots them from a boat. Nutria have been feral in Washington since the 30's, fur farm escapees. They really tear up the dikes and the district is happy to have the help reducing their numbers. The mild winters on this side of the mountains is favorable, and they are REALLY destructive.

Ok got it. That sounds good.

unloaded is right, you just did the humane thing and finished it off… Definitely uncool when critters get “too comfortable” around the homestead…

@L.Leon In all honesty it wasn’t the most humane in the sense of a timely dispatch. First shot through the fence was a neck shot. ITT went down and I thought it was done. Pup ran over there and when I looked through the thermal again it walked out of the kennel dripping blood from the neck. When the pup didn’t attack it, I called him off to get him out of my line of sight. I’m still working on him discipline with this one. He’s good when he knows I’m target shooting, but because I’m not out here shooting everything moving it’s hard for him to tell when I’m going to shoot an animal outside of squirrel hunting. We see rabbits, raccoons, possums, foxes, deer, horses, armadillos, and an occasional coyote. I’m usually shooting at coyotes and dillos around him. We saw a fox later that night and before I could discern Fox from coyote, he gets in my line of sight and enters a stare down. Turns out it was a fox and I didn’t shoot. Anyhow, after the pup came back to me I shot the possum until it stopped moving. I’m pretty sure it was gone before it stopped moving but I owed it that much to be sure. I emptied the mag with the last two or three shots up close. I don’t like to pretend things aren’t the way that they are so I wanted to clarify that. It was probably a 2-3 minute ordeal. 2-3 minutes is a long time to fight (as humans) and a long time to watch or allow something to die in my eyes. Although Texas hunting regs requires me to let a deer bleed for a half hour before attempting to retrieve it.

Hi everybody. Recently i bought a Daystate Red Wolf HP. The trigger is too hard before break or shooting...If i´m correct supose 2º stage is too heavy. I must loosen the screw of 2ª stage, right? I use PCP for benchrest...so i need a precission trigger. What weight is recomended for match trigger? I would very grateful with some tips about this issue. Thx

Fun testing. From the ballistic gel videos I have watched I dont think most pellets deform or expand at all at normal speeds. If you push them fast they can do some wild deformation depending on the pellet. The Hades/Atomics kind of expand at higher speeds. I shoot mine at ~980fps.

That is my problem exactly. I only have line of sight to 30-35 yards, then a steep drop-off. Over that hill are a bunch of holes dug. There is no follow up shot. They only have to go 10-20 feet to get to those holes. Had one sitting on the corner post of my horse corral (35 yds) last week. Only had an offhand shot. Hit him solidly in the body. Heard the thwack. Knocked him clean off the post to the ground. Ran out there but could not recover him. I was using my .22 Notos. Due to the proximity of the holes and lack of a follow-up shot, I may switch to my M3 Impact 600mm in .25 or even my Wildcat M3 BT 600mm in .30

Put the dot inside s small 10 ring and it's not near as difficult as in the bigger circle. It surprised me for sure. I think we will find out any score over 50 percent is pretty good. My best is 16. Average probably 10. Real close does not count. These target were donated so only enough for 1 or 2 matches. Then it will be a more typical target with the black on white scoring rings very close together and a small dot. It will be the same thing, hit the dot or get a zero. I bet those scores go up. They are another full box of donated targets.

I like good ball end hex wrenches, extra magazines, and lots of scope mounts for the right fit.

I'm getting ready to buy one. Lighter weight and added shot count is worth it to me.

Do look at the other FT clubs ( four of them) in NC also.

Yea, the first sleeve I got didn’t have the “nipple”. The latest sleeve they are identical in all measurements and weight. And they shoot exactly the same. So for some pellets, the AEA and JTS are clones. In .30 caliber same deal with the 45 grain versions - identical in dimensions and performance.

The chicken crosses the road to prove to the opossum it can be done.

Now I need to adjust the absorber travel. There is a small hex screw that adjusts how fast air escapes as the absorber travels rearward during a shot. Good video on YouTube. Enjoy your new hole puncher!!

Yup that’s the one I’ve been trying to find any vids of it online and can’t seem to find one

Gotcha, I had one for a bit, great shooter, super quiet moderated.

Nice...
Mine likes the 14.3 Premiers from a while back... just happen to have a good stash. It also likes JSB 13.4s and 15.89s as much. VERY accurate ... Mine is about 19 ft lb.

Interesting thing, most of my unregulated ag's are filled to 2300 to 2600. It had been a while since firing mine so I filled to 2300 and it took 75 shots to come to peak at 1700 psi. I fill to 1800 now and can get 40 shots with pretty low es at 19 ft lb... pretty crazy because that's not much air...

I just kept it on the tether at 2800psi.
When I'm playing with the chrony or accuracy I like to remove the variable of bottle/tube pressure.

If i were a hunting guy that would probably be what I used walking about. So light. Would have to buy more magazines because I sure wouldn't watch to try to reload those mags outside.
