So.....what did you shoot today?

[Rick67]

I was shooting my 853 and it looks like it needs another rebuild.

It wasn't that long ago about a month or so, that I replaced the O-rings and valve with the rebuild kit.

Everything was find until a couple of days ago when the last shots of the day dropped from the POI about 1 1/2".
The next shots were about 2" low. It was getting late so I just put it up.

The next day nothing changed, but for an unknown reason, it started firing like normal with normal velocity.
That was a day and a half ago and now it's dropping shots again.

I'll bet I haven't put a thousand rounds through it since the rebuild.

Is this a usual problem inherent of all 853s ?

I really don't want to do this again, especially so soon after the first rebuild replacement kit.

I would like to hear from those who have had to rebuild theirs more than once in a short period of time.

Thank you so much.

Ron

PS.
Does this O-ring look too narrow?

I’m not an expert on this, but the groove seems perfectly normally for that O-ring.

Years ago, I have sold thousands (all over the years) Dutch-made Dofra backpack sprayers to banana plantations, and the dual O-ring (Viton) 2-groove brass piston rod had a bit of allowance just like yours for the grease to house themselves.

Thanks , Richard.

It just looks like a mismatched O-ring.
I really don't know how they're supposed to fit.

Took a few shots at cookware hanging from trees in the backyard.   I'm still recovering from the horror of shooting that B3-3.

What happened with the B3-3?

Do you still have all your fingers?

-W

LOL.  No accidents occurred.   The horror is from the horrible wood, horrible metal, horrible trigger, horrible fit and finishes.   I do admire the rubber faucet washer I jammed in for a breech seal.

[Spacebus]

Pellet tested the Gamo Wildcat for "green" PbF ammo.
As expected the H&N started high at 9.57gr and the GTO at 11.75gr put down a tighter group.  There's about 3-5 shots through the ragged hole in the bull.  Either pellet is more accurate than my "artillery hold" technique.  This jumper likes a bag just past the trigger guard.....I think there's a couple "dang that GRT4 is light!" flyers as well..lol
Also shot the .303 Challenger with the just received NSA .303x61.5gr very nice groups with a 3800 fill consistent low first shot 4-7 ragged hole bull 8 or 9 could be low as well.  The 40:1 NOE .300x63gr grouped okay but wider than the NSA and the flyers would be giggling ninja squirrels.  If anyone has a true .300 barrel PM me about the mold.  Looking at the 62gr Accurate Molds product spec at .303 +0.002/-0.000 for 40:1.

A friend of mine has been hand loading for PBs for over 50 years, but wants to get a PCP for shooting steel in his back yard. Do you think an AEA Challenger would make a decent first PCP? I have a 457 Bullpup, and it's been essentially trouble free for me besides a cracked magazine cover, but I only single load it. He's specifically looking at 30 cal for having enough energy to knock down his pistol silhouettes. Has yours required any tinkering?

I got the gun from SmythG and lol he bought a brand new one to fill that spot.  Stock with a little starting fill adjustment you can get to 8-9%ES around 85-95fpe with Hatsan pellets from Field Supply or .303 NSA 47.2s (from NSA no longer offered in 303 from PA).
I tried to insert a Huma reg because the BinTac Reg is no longer available.  Then I tried to make an SSS with spring changes and now I'm trying to cast slugs.
None of that tinkering is necessary. 
85fpe tune should knock down steel plates.
With the 70x25x2mm spring and a shim I peaked in the 115fpe range with a 4,00psi fill which could knock down anything shy of yearling deer IMHO
Best of luck.
I would also suggest the AEA 9mm as he could probably shoot one of his pistol boolits 80-125gr (worst case single shot if too long for the mag).
Best of luck IMHO it's one of the best $375 hunting PCPs out there

100 FPE should be plenty. I think even 50 is probably enough. Next time I see him I'll show him the AEA guns.

Full disclosure James is accurate with .303 Challenger as I can not hit the broad side of a barn with .300 calibre Boolits in this gun, but it's one ragged hole with .303 Ammo....you have been warned :-)

My fake 3622...
After I put the bench and chairs back on the shootin shack deck I brought the 12/120v OrcAir compact compressor out and set it up on the bench.
That gun must have a very slow leak because it was dead flat after sitting a few days. But the little compressor that could filled it to 2k in about a minute and a half. It's going to be a great unit for topping off these 2k guns right at the bench.
That gun is LOUD !! And the metal Red Shed wall, tin roof and side curtains make it even louder.  I love it !!  Sounds like a 22LR.

Whew. That's a relief. I thank the Good Lord every time I successfully cock, load, and fire that airgun and it miraculously doesn't break into pieces while crushing my favorite pellet-loading finger.

And yet, I still sometimes take the risk. Don't ask me why.

I named one of mine

On a crazy whim, I dug out the AA S400-SL Carbine I got from Don years ago. It's  been in the case for months.
Still had a full 200 bar on the gauge!!!
 I never see another S400 in a side lever but this gun is SWEET
It still loves the H&N FTT's in a 5.53 head size...Thank goodness because I have 2000+ with it's name on them.

Spent the afternoon with NSA slugs, Allen wrench, hammer springs and the .303 Challenger.  Ended with a 100-110fpe, 8%ES sexy ragged hole tune.  We'll see if I can duplicate it at the LGR at 24yards.  I will be placing the NOE68FN 2 cavity on the WTS/WTT thread. The SPA800r had a 5-7%ES at 16fpe with the NOE hand picked pellets.  Ended the day with the Notos and hand picked NOEs 3-5fps ES ..big smile.

Nice grouping.

 I shot the GK1 fine tuning the new scope addition. I went between that and the FX DRS aside from some squirrel moments 

[airgunaut]

Cold wind drove me back inside after I attempted to practice offhand standing outdoors with the P3. Settled for sitting on the floor and using a bent knee for some support. When I stepped outside again it wasn’t as cold or windy, so I fired another 10x each side at a mini soda can, also sitting on the ground but at 33’ instead of the indoor 19’.

Taking advantage of the not-so-bad weather lull between storms, I then fired the 880, 10 pellets split between the can at 50’ and up at a dead tree at about 65’. Sure is nice having a scope.

The Blue Streak was next. After firing 3 pellets at the same tree and 7 pellets at an empty Herdez salsa can and noticing that the hits tended left of POA, I went inside and adjusted the peep sight. After dinner the calm still held (but now cold), and I verified the sight adjustment with 5 shots at the same can.

Shot my Umarex PPK/S co2 bb pistol out the man cave window. Fun stuff.

It's been a journey.  Many thanks sir!

Impressive power and consistency out of the 800r! My 22 Stormrider (PR900r) with altaros reg manages 42 shots per fill at 699 FPS with an 11.1 FPS ES and 2.7 FPS SD. The SPA regs must be getting better. With the Altaros reg in my PP800 I wasn't making thag much power or getting many shots. It's now using a 177 rifle barrel, small bottle, and getting 24 shots averaging 954 FPS, 26 ES, and 6.5 SD.

I did manage some time to shoot a bit yesterday.

Many thanks!  I really wanted a 25 yard squirrel sidearm for when I'm in a tree stand with some other tool or scout walking with my run-n-gun pack.  The fpe is the same as my scope busting jumper.  The air cylinder is so small I only get 7 shots (one mag) with this tune, but that;'s all I need for hunting.  The PP800r and Notos have got me considering packing the hand pump this fall....hmm....Already adding weight if I get the camping stool for ground blind sitting......

Or set up a mini fill bottle< I thought I had a picture of one of mine, but can not find, here it is in a video.
