Got my new Hatsan 125TH .25 cal

[JoeV]

Stopped by Pyramyd Air this morning with my brother and we picked up our ne Hatsan 125TH rifles in .25 cal.. After lunch at the Chineses buffet, we each headed to our respective ranges to break them in.

I cleaned the bore and pulled swabs thought until they were coming out clean, then took about 30 shots over the Chrony down range just to get it warmed up.  First shot logged 901FPS with a JSB King 25.4, then settled down into the low 700's.i didn't expect that from the first shot. LOL

I then set forth to do a baseline data capture with 5-shot groups with the four pellets I have in .25, and recorded the results. I took a break and mounted a Centerpoint 3-9x32 scope on a 3-screw one-piece base, and zero' the scope on  sight-in target. Changed targets and started pumping 5-shot groups down range to see how they grouped. After each group I checked the Chrony and updated the average FPS in parenthesis next to the original speed. All four velocities dropped as the spring was settling in, and I'm hoping the numbers. Don't go much lower.

At the end of the session I had shot over 100 pellets, and was pleased with how it was shooting. Another hundred or so pellets should tell the story, and I'll do that in the next day or so.

Sorry for,the sideways image. I rotated the image but it wants to appear sideways. Darn kids...LOL

Over 100 shots! Wow, how's your arm and shoulder feel? I know if I'd put over 100 rounds through my XL1100 I'd be hurtin' for certain and I imagine the cocking effort on the 125 is probably higher. Thanks for the post, enjoy your new toy!

Ed, my arm and shoulder are fine. The cocking force is specified as 50#, but it doesn't feel that strong.  I'm a semi-retired handyman, so my work is very physical which keeps me in shape. Plus, I'm only 65, so it shouldn't be an issue for at least another ten years. 

Jay, I had higher expectations with these numbers, based on a video I saw awhile back. Maybe that guy did a tune on the gun before running the numbers. Once my confidence increases, I'll be getting into the gun to cleanup the rough edges and lube it. But for now, I just need to get some more lead downrange to break it in. The tuning videos I've watched make me crazy listening to some of these guys drone on and on and on! I need to find a nice concise video without all the side chatter. IMO, 36 minute videos are wayyyyyy too long, and need to be cut back. I fell asleep watching one last evening.

Looks like a great way to spend a day.

I agree w/the comment on the videos.

Thanks for sharing this! 

I'm still not sure about that 1st sentence though...

"Stopped by Pyramyd Air this morning with my brother and we picked up..."

I think for most of us this would end badly.  Very badly!!!

I know the guy you're talking about, he always jams packs about 10 minutes of info into two hour time slots (split across multiple episodes) ...  Unfortunately there aren't a lot of breakdown videos on the Hatsan 95 and 125's that go beyond a glimpse of a compressor and slathering of grease.  Feast or famine!

For pictures I wish I still had my links, there was a sight in Poland that Google Translate did a decent job on that had a bunch of pictures.  Hopefully you won't have to tear into her, but I can tell you it's not overly complex - just maybe perhaps a bit crude on finish.

Just make sure you don't still have dieseling before beating your scope up with it, they can really hammer a cheapo scope to death quickly

Here you go...... http://sharg.pl/pol_m_STRZELECTWO_Wiatrowki-i-akcesoria_Akcesoria-do-wiatrowek_Czesci-serwisowe-3102.html?filter_producer=1407238728&counter=0

I don't know if they actually ship parts to the U.S. or not. I sent them an email a few weeks ago asking and haven't received a reply.

Ran another 50 pellets thru the 125 this morning, and saw further erosion of FPS. Not sure where it's going to settle at, but I got the bug today to dissect the gun and do a debur and lube. Step #1 taken with some scrap lumber and a 4" c-clamp. I chose this design because I had everything on hand in stock to build ot





Tomorrow will be the day to get my feet wet on this bad boy.

Watch for loose pins when you take out the trigger assembly!

I use rubber tubing or perforated elastic bands to make temporary retaining clips when working with the quattro trigger.

I use blue painter tape to wrap the pins.
There is one pin that holds the main sear you need to knock out.
I made a small wooden one that I can drive in to clear the mounts but hold that sear.
I then pull the real pin.
You'll figure that out.

Also great ideas!

I'll have to remember that for next time.

Thx!

Nice job on the spring compressor!

Probably the hard way. LMBO!!! But I won't do it again. 

[Gut2Fish]

If you don't hold that main sear in place it springs out of position. Not a big deal but you do need to fold it back on self, put in position and hold with a small piece of wood when putting trigger block back in. Then push the wood out while driving in the metal pin.

This is the pin in question. The wood or whatever used to hold sear in place has to be narrower than the welded on metal so the trigger block will come out or be able to be  put back in. Another photo of that pin and other two near safety, one holds trigger block and other end cap.

 Looks good cant wait to see the numbers after the tune

Thanks for all the input and information. I got it all apart and believe I found out why I'm not happy with the numbers. Can anyone tell me if this seal is supposed to look like this, or should it be smooth all the way around? Looks like it was a short shot in the mold when it was made, because it actually molded a radial channel in both directions from the verticle.

Either way I'm calling PA to see if thy will ship me out a new seal, rate than to return the gun for another one. I've gone through all the debur on the stamped openings with fine files and emery cloth, and don't want to go through that again on another gun.

[SteveP-52]

Nope, it's not supposed to look like that. JMO but ARH makes a way better seal... I know the Hatsan one would be free but I'd rather spend the $12 for the ARH version, did and so far have replaced them in 2 of my 5 Hatsans.

  PA will have you take whole rifle back.my 125 shot GREAT until the fps dropped to 540.hatsan said I put oil on seal and melted it,i didn't they lied.i no longer own it.good luck.

[Gut2Fish]

If PA will ship a seal for free that's great. I'd rather have the seal mentioned above, keep the seal from PA (if they will give it free) as an emergency back up. His moly paste is the best on market also. Highest percent moly.

This is the seal: http://www.airrifleheadquarters.com/catalog/item/251485/6616786.htm

His Super Moly:

I just looked at the PA seal, an aftermarket seal and has good reviews. I guess it doesn't matter much as long as it's not a stock Hatsan seal. If you need moly paste then I'd go with Macarri and get an extra seal for your brother when he needs to tune his. Combined shipping to keep price down.
