I bought a BSA Meteor Super from AoA because of this very reasoning. It does shoulder great like a 50S and the shot cycle is great too but unfortunately the trigger and accuracy has proven pretty sub par. Granted it isn't a high end gun and is basically a prettier/better built Gamo but I was still a bit disappointed with it. If Weihrauch released a gas ram version of the 50 I'd absolutely give it a try.
You only have 2 choices should you decide to tinker. The HW90, which of course means finding the pump kit or an older Hatsan Vortex gas ram that has the bleed screw on the back end of the ram. I say older because from reading a few different forums, Hatsan appears to have taken that feature off their newer gas rams.
Exactly . and HW pump is $299 or was it $399 and the gauge is another ???$80 , never researched trying to use a Hill pump ?
Only know from what I've read about it, but look into bicycle shock pumps. Supposed to be right around a $100 bill and do the job just as well as the way more expensive one.
There's a kit in the uk , but the cost is just a tad cheaper . Also fepending on the ram the pcp pump may be too much. Some use a motorcycle shock pump for them .. anyway just fact check all that.. ( fuzzy brain, ya know)
Although it's a collectable this Theoben Evolution .177 tuned to around 12 fpe is one of the nicer shooting "spring guns" I've ever shot...the gun is so comfortable to shoulder and easy to cock...just a pleasure to shoot...the gas ram has zero changes in fps in the two years I've owned it...their not easy to find but are as nice to shoot as anything out there. I've been looking for a .20 caliber example for years.
I used a Rockshox high-pressure bicycle shock pump and adapter. The pump has a Guage on it. The pump and adaptor cost me 70 dollars out the door at a local bicycle pro shop.
If it helps any..
Accuracy SHOULD be the main concern. Even the most powerful break barrels are still pretty darn low powered. There is really no game that a 32fpe Hatsan 135 will take that a substantially more accurate 16fpe HW95 can't take. Springers are a game of shot placement and 16-20fpe is already more than enough to do the job on appropriate game.
. I found a business several hours from my home which repowered gas rams. My ram couldn’t be re gassed but I found another ram the same size which was filled to 500 Newton’s, perfect I thought. This picture shows both rams together. I had to make a plastic sleeve so the new ram would fit snugly. I put the rifle back together, loaded it and pulled the trigger. Pffffffffft was the sound I heard. Pellet still in breach. Long story short it was a different type of ram, one that it more suitable for opening a car bonnet then propelling a pellet.
You can buy the adapter or they have a kit with pump. Heck of a lot cheaper than any thing here in the states
The 135 is fairly easily converted to spring if you can get the parts. End caps are a bit different, so you'd need the spring version end cap, spring guide and spring to change it over. Don't know how easy or hard it might be to get hands on those few parts but an email to Hatsan should answer that.
