Hello Gents,

Was surfing around looking at air gun springer modding kits, came across Wolf Airguns. They have some performance data listed for their Springer tune kits, I have given it some scrutiny.

Tuning Kit for Hatsan MOD135 (I'm just obsessed with it) http://www.wolfairguns.com/product_info.php?cPath=27&products_id=62&osCsid=bba37e51dc152aaa883aa49da9038cc3

It claims a velocity of 400m/s (1312 fps) for a pellet of 0.42g(6.48Gr) for an energy of 24.77 ft-lbs.

There a video of a man testing his MOD 135 .22. https://www.youtube.com/watch?v=JCAprsxsDyc.
This is the oldest proof of chrony testing the mod 135 I could find, to try and eliminate the Vortex piston models. I am thinking the rifle in the video is a early springer.

In this video he is pushing a pellet of 18.13Gr (JSB King Heavy) at around 785 FPS. This gives me an energy of 24.81 ft-lbs.

Mod Kit rated at 24.77 ft-lbs, actual energy of the .22 around 24.81 ft-lbs.

The .25 Cal Variant, is proven to be a 29.25 ft-lbs rifle. http://www.huntingaccuracy.org/hatsan-mod-135-25-cal-performance-overview/

Thus I cannot see an actual advantage to the mod kit? Could there be such a difference in the power plant between these rifles .22 and .25?

No need for a tune kit on a 135 Hatsan. There is a need however for a better piston seal and a good lube tune. Out of the box I was getting 27fpe average with different weight pellets . The shot cycle was horrible and was dieseling badly. Now with a replacement seal from ARH a shimmed breach seal and some lube in the right spots it's an excellent shooter. 31fpe with 18.1 gr jsb pellets. The stock performance was a little low due to the seals . I got a copy of Chevota's tuning bible from him and used it to the letter. Great guy and even better instructions on how to tune a springer.
Where did you find your 135 from ? I would like one in .25 cal .

I do not have a 135 yet, there is a brand new .177 model in my nearby City (For only $200!!). I was investigating that if I put a .25 cal barrel on it, converting from .177 to .25 would I get the same performance as if I bought the .25 Verson. What do you think? I am very bored of .177 and .22 calibers.

AFAIK the .25 Cal MOD 135 isn't going to be carried by Canadian dealers until next year sometime.

I am not replying about your specific rifle inquiry, but i have installed 3 Vortek kits to date. PG2 type. HW springers.

You can purchase different kits rated by FPE. I use the lower powered ones, 12FPE or so.

So if you have a full power rifle, these kits will reduce the power quite a bit, if you have a de-tuned rifle, they could take you over the PAL limit.

A lot of folks, myself included, install them to smooth out the shot cycle. The kits come with double or triple spring sleeves, oil, and usually a piston seal, spring, etc etc.

They work, period.

I dont want to debate the cost, whose kit is better, and so on, just trying to answer your question.

Although the HW line is very, very good, you cant beat physics...having that power in a springer comes with consequences. Some recoil, noise, harshness, and so on. Obviously if you hunt with air rifles, or shoot 50yrd plus for fun, or just like the power, then the lower FPE kits would not be for you. I think they have 19FPE or 21FPE kits as well, although I've never looked in to it.

If all you do is put holes in paper as I do, then (FOR ME) there is no need to have 1200fps in .177 although I do find anything under 600 or 650 pretty wimpy over 10 meters.

I would try to find a barrel
First before buying it. As is in .177 way overpowered. Great in .22 not sure about the .25 although should hit 30fpe easily. You may have luck finding a barrel from EU somewhere.

What if I could get a .25 marauder barrel or a ,25 Fx barrel. Would there be a hope of retrofitting it for the springer break barrel?

Hobbyman has it figured out ;) Runnin circles around the guys in the links...
No diff in the power plant between calibers, it's how the power plant works with the barrel. 177 is simply too small for that gun so it'll cost power, and 25cal would make more power than 22. If Hobby is making 31 now then I'd imagine 25 will net 33-34 (if tuned like Hobby did, including that seal he got). I can't speak for the vortex version other than some people complaining about it making the 125 weaker, so if they use the same spring, and I'd bet they do, then it'll be even worse. You can always mod the coil spring to be quieter, which I'd imagine Hobby did? It can be made as quiet as a nitro...
I hope you know how big and heavy that gun is. Some people mail order only get a shock, then return it. Some people can't even cock it.
I consider a Trail XL or Diana 350 to be borderline too big. I had a 125 with a super light syn stock and I gave the gun away. Too heavy and too hard to cock. Accurate, and 28ftlbs in 22 but I just wasn't feelin it.
UmarexUSA is where I'd try for parts (I doubt there's a UmarexCA) and hopefully you won't have to go thru a middleman like with Crosman. My guess is at least $100 for the barrel, then all those fees and shipping to CA would end up at 150? Middlemen charge double for Crosman parts, if so then $200?

Here's a link to a euro site that has barrels. I tried to contact them with no luck. If you do manage to get them to ship one to you ( I'll take one ) . As Chevota mentioned the weight alone makes it a rifle that is hard to carry if hunting with it. I'll be honest and bought mine for bragging rights , "the most powerful break barrel available". Now if you want real power , save you pennies and move into pcp , and a hand pump.

Alright well it was the only trip into the city for a few months, and I got the 135!
It's not about bragging rights as such, just to have the best power available in a break barrel. This is my third Hatsan, I find the sights disappointing on all three. But I'm going to machine myself a new blade for the muzzle soon. I am getting geared up to make some more parts for my co2/pcp air pistol project. Until I complete this project will I make the decision to get a pcp pump, or make my own.

Can you message me the link to the euro site?

Thanks Hobby,

I too have sent an email inquiring about the barrel. I have found another site, you have have already seen this. http://arms.bg/en/product/1931/replacement-barrel-hatsan-6-35.html

I do not think the 125 barrel and 135 barrel would be different?

You may or may not be able to get barrels from the States. None of the normal barrel makers in the States can mail a barrel to a Canadian shooter. They have to go through too much red tape. It is possible air rifle specific barrels will be classed the same as muzzleloading barrels and there may be no problem - I don't know.
The US/Cdn exchange rate is a killer.
I just bought an open sight from Brownell's costing $169.00 US- it was almost $300.00 by the time I got it. Customs and sales taxes on top of US shipping and retail + 1.45X, I think for the money exchange.
I would look into it if I were you.
Lothar Walther .25 barrels from D&L are around $369.99 iirc (call Kelly). https://www.dlairgun.com/Air-Rifles/
Also try SSSO before they close. Might get a really good deal there from Rhonda. https://www.specialtyshootingsportsoutd ... rguns.html

I never even seen the SSSO Store before, it is too bad they are closing out! They have great inventory, is there any reason why they are closing?

There is a .25 Cal barrel there for a hw90. I may check it out after I get in contact with Hatsan USA. https://www.specialtyshootingsportsoutd ... oduct_info

Man they have some cool stuff, some really great high quality air guns there on sale!
