Hatsan Flash-R QE question

[Back_Roads]

 My next step would be a padded vice and a mallet to wack the wrench, that may cause damage to a warrantied part

[Blowpipe Sam]

Man I’m glad I started this thread.  There is lots of good information coming out.  Thanks guys!

I think I would wait to see what Hatsan has to say before doing anything. heck, they may just send a whole new tube assembly and tell you to keep the one you have. Then you could put a blow torch and 2 monkey wrenches on it if you want to.

Bismillah!  It held air overnight!  Not surprised really since it came fully charged but an encouraging sign none the less.  Next I’m going to try and pump it back up to 2500 PSI.  I expect that to take a lot more work than the Raider or the 3622.

Zeroing and chronographing today.  I’ll also be searching for the right pellet for it.

Man this thing is long!  Looks like something out of Star Wars too.

[Blowpipe Sam]

It is presently zeroed with JSB Kings at 20 yards.  If my hands were steadier it will stack them at this range.  I'm a little shaky today so I'm satisfied with one ragged hole.  I filled it to approximately 2300 PSI and 20 shots brought it down to approximately 1900 PSI.  It took better than 60 strokes of the pump to bring it up from 1800 to 2300.  The memsahib asked me a question while I was pumping and I lost track.  In a few minutes I'll pump it up again and proceed with chronograph testing.

I'm in Bill's Camp on this one!  At this point the ball's in Hatsan's court.  If they send me the whole air cylinder/fill valve assembly and tell me to keep the old one, then I'll go all out ape on it and see if I gan get it apart and repaired and set it aside as a spare.  But, I suspect they will either want it sent back to them.  I'm just hoping they will send the replacement first and let me send the bad one back in the same box.  The other alternative is them asking that I return the entire rifle for a replacement.  I'd prefer to just exchange parts, but they will ultimate dictate how it will go down...

[Blowpipe Sam]

Hatsan CS has been pretty good about sending me parts.  I'd bet on them sending you a new cylinder.  It would be nice if they let you keep the old one.  If I had a spare I'd be tempted to "Open her up and see what she'll do".  But that would be kinda pointless in .177 unless you want to shoot slugs at hypersonic speeds.

I bought my chronograph at least two years ago.  Today the very first 9 volt battery I ever stuck in the thing died.  So no chronograph tests until I go to town this evening.

Quick chronograph report.

25.39gr JSB Kings.  Average velocity 772 FPS.  33.7 FPE
20.06 H&N FTT.       Average Velocity 827 FPS.  30.5 FPE

I’m betting a little more HST tension and you will be in the mid 800 range. Just be aware, there is a set screw accessible through the side of the breech that needs to be removed before making any adjustment. It’s the same as the regular Flash and ther is a good how to video on YT.

[Blowpipe Sam]

Thank you Paul.  I'll be checking that video out.
Next I'm going to fill the gun and run a long string on the chronograph to find out where it falls off the regulator.

Here's a link the video I was talking about:



After you remove the stock and cock the lever you can see the grub screw through the small hole on the side of breech.  I think it's a 2.5mm hex key, if I remember correctly.

Still waiting to hear from Hatsan...  I may have to ping them again tomorrow if I don't hear anything.  They only pay return shipping for 30 days after purchase even though the warranty on a refurb is 90 days! Since I contacted them the day after I received it, that clock should get extended if it takes them a week to get back to me!   

[Rat Sniper (AKA: PaulT58)]

UPDATE:  I heard back from Hatsan this morning.  They won't send parts, but did offer to let me just send in just the air cylinder and fill valve for repair.  I'm good with that and requested a return label.

Well, I still haven't heard back or received a return label, so I thought I'd give it one more try before throwing in the towel.  In the e-mail the Tech mentioned they use rubber in the vice and a big Phillips head screwdriver to break the valve loose!  So, I wrapped the air cylinder in some rubber weatherstripping I had laying around, cranked it down as tight as I could go in the vice and grabbed the biggest Phillips head screwdriver I could find.  I gave it a good yank and it broke free!  I didn't even have to apply any heat!

So, after removing the fill valve assembly from the air cylinder, I disassembled it and replaced the o-ring.  The old one was pretty shredded.  I lubed everything up, reassembled everything and filled it to 250 BAR.  So far, so good!  No air rushing out like before and no noticeable audible leaks when placing the fill valve near my ear.  I'm going to let it sit overnight and see where it is in the morning.  Hopefully, this fixed the problem and I can get back to shooting it tomorrow!

[Blowpipe Sam]

I'll burn some joss to the airgun spirits tonight Paul but I think you got it.  I've pumped mine up about ten times now.  Chronographing, zeroing, and plinking I've shot about 300 pellets through it.  I haven't shot it down to the point where it falls off the regulator yet.  I've been averaging three magazines between fills because I don't feel like shooting it down and then having to pump it all the way back up.  Starting at 2400 PSI I get thirty very consistent shots (SD under 10) which brings it down to 1400 PSI.  It takes about sixty strokes of the pump to bring it back up to 2300-2400.  The way my shoulder is right now those last 20 strokes are hard! 

[Rat Sniper (AKA: PaulT58)]

Thanks Capt’n!  I need all the help I can get, so any jewjew you can send my way will be appreciated!  Hopefully, I’ll be slinging some lead from it tomorrow!

The Flash R held air all night long!  The gauge didn't budge from when I filled it yesterday morning.  I spent some time testing pellets and slugs today.  It did decent with NSA 15gr slugs, not excellent but acceptable.  Pellets were the real shocker.  The JSB Redesign 13.8gr were all over the place!  With the way the heavy slugs performed I expected better results from these.  The Crosman Preier Domed, 10.5gr performed the best!  Small clover leafs, even when stretching it to 50 yards!  Next were the 10.65gr H&N Barracuda pellets.  The slugs were shooting around 890 FPS, the CPD's were right around 980 FPS, probably a little fast for those, but accuracy was there.  Now to wait for a rat or mouse at the feed station and see how it does as a hunting rig!

 Paul, Good news on the Hatsan Flash-R Refurb! You should be able to do a bit of HST to fine tune for sure . I did a bit of tweaking my old FlashPup to handle slugs
 for G-hogs(.22), then back again for "barn work". I'm looking forward to the Bait Station Cafe report .
 
 Cap'n Carter , I see you're getting some good results also, looking forward to your adventures also!

[Blowpipe Sam]

Glad to hear you got yours sorted out.  A 10.5gr CPD arriving at somewhere near 980 fps equals a lot of hydrostatic shock.  Looking forward to the video.

I'm functionally ambidextrous when it comes to shooting. but I can't shoot right handed since my shoulder surgery.  I don't have any accuracy issues shooting left handed but the Flash is definitely a gun that you operate from the right side.  I have shot mine from a lawn chair with a tripod for support and achieved very good accuracy at 35 yards.  I haven't shot it from a bench with good support yet.  My hands are not the steadiest right now. LOL!  When I don't throw the shot they go right where I was aiming!
It does not like 20.06gr H&N FTT.  It does like 25.39gr JSB Kings.  I'm ready to branch out and try some other pellets in it.  I have a few 27.47gr Baracuda Hunters but I need to order some different stuff to try in this gun.  Maybe slugs?

I'd like to back off the HST and see if I can get a consistent 900-915 FPS with the CPDs.  Right now it's setup and zeroed at 50 yards incase the mouse I've been tracking shows up tonight!     A mouse at 50 yards with a Hatsan .177 should be quite a feat if I can pull it off!

Thanks Capt'n!  Stay tuned, hopefully the mouse will be out early tonight!  He was out there at 5:15 this morning, but I had zeroed the scope or test any pellets, so hw got a pass...  Those days are over!   

I can't do $h!t left handed!  Some days I can't right handed either!  I really messed up my right wrist a number of years ago and have been nursing it ever since.  It's about at that point where it's going to take more than a brace and a few Advil to ease the pain!  But, the Dec is telling me I'd have limited mobility after they fuse the bones together and recovery could be 6 months long!  Right now I just have to deal with it feeling like someone jammed an ice pick into it, but that only when I over due things, so still feeling the occasional ice pick stab is better than 6 months in a cast with zero mobility!  Now sure how that would impact me shooting!
