Seneca/Sam Yang Samyang/ Seneca recluse

[Airgunmann]

I've got a leak in my recluse 357 after I installed a new valve from lethal air pretty sure I tore the oring since I had a piece of oring fall out when I was reassembling it well I tested it and it's at 200 ftlbs well since I've got to tear it back down and find the correct oring I think I may make a peek poppet and see if I can't squeeze a few more fpe out of it

I'm no expert, but after looking this rifle through I believe there is a lot of ways to increase potential energy. I feel like the poppet/valve return spring is tremendously heavy for starters.

 

[Airgunmann]

Yeah they are

Just opening the valve front get's the most gain (200fpe) an improved poppet is good for the nest 20fpe. Then you pretty well hit a wall, unless, you can do the needed fabrication work to make the barrel fit inside the "receiver" instead of the barrel having to slip around that pesky nipple. That is THE flow restriction. Really want to get into it (machining barrel) some gain also to be had in shortening the barrel just a bit on the loading gate.

Not much pointing porting this large as that barrel mounting nipple is about .25 ish so turbulence is created but they are fun.

Out of the original valve I was able with original transfer port I was able to get it up to 180 ftlbs got a leathal air valve and had to port out the receiver the smallest hole going into my barrel is .250 it has a heavier hammer and spring and will do 200 fpe now leathel air transfer port is quite a bit larger than the original only place I have left where I good gain some performance would be peek poppet valve I can't go any larger into the barrel or I'll be threw the oring sealing the end of the barrel

 

[Airgunmann]

Poppet is still huge in there valve Id be able to make it quite a bit smaller with peek which would lift off the valve faster and easier if I could hit 220 fpe I'd be happy

So to my surprise to went to rip into my recluse and found it was still holding air almost full I put in a 178 gr NSA slug got 722 out of it refilled to 3200 psi and I was up to 218 fpe at 745 fps with 178 gr so I'm not touching it I won't over fill unless I would have to prove it's over 215 fpe to use it for deer hunting if i ever get the chance in MN

I have a Shin Sung Fire .357, I'm pretty sure it's very close to the same gun as the Recluse.

With mods to the factory parts I can get almost 250fpe at 3000psi with the recluse. A newer one. Some of the older valves are much more restricted.

 

[Airgunmann]

It is the pesky nipple that barrel slides over . I got the nipple opened as far as I want to go
