I bought my first 362 when a local store had a sale $99 then they went down to $79 so I had to get two more. So now I have a .177 and .22 with steel breeches, TKOs and barrel mounted adjustable rear sights. Plans are to slap on the .25cal Baker 725XL barrel with big bore breech and screw on TKO that I have laying around to see how it shoots with lighter weight .25 pellets. It's one I swap out on a short barrel .25 carbine Disco tube build when I want a longer-range barrel. I would only do 8-10 pumps normally so don't know if the power is there for .25cal. Pumpers are a favorite and I like the idea of having all three calibers.

Pumpers are a favorite and I like the idea of having all three calibers.Van,The power is there, but needs to massaged out. When we built ours, I put a valve in mine with the throat opened up. I don't remember how much, but it's pretty big. Maybe 7/32"? The exhaust port, transfer port, and barrel port are .166". Mine wouldn't dump all the air either, so I made a hammer spring guide out of a 4mm allen bolt and put it in the hammer end of the spring to add weight to the hammer and add preload. Now it dumps 11 pumps. I cut out a section of the piston and added some threaded stock to make it adjustable. I also added a wool felt oil wiper. Now, with a few drops of 30ND it feels almost like it's not building pressure. At least until the trigger is pulled!It did 651 with an H&N 20gr pellet, and 571 with JTS 29grs. Im also using the baker breech, I hate loading the H&Ns, they're a royal pain to load.
Van,When we built our 25s, my friend used a Baker high flow valve, his gets way less velocity than mine. If you're going to build one I would take the time to open up the exhaust side of the valve as I related. One thing I forgot to mention, I used a Marauder exhaust valve stem, they're harder than the white ones and will stand harder use. They're available from crosman. Do the mods, they're well worth your time! And, yes, VERY ACCURATE!For my next 25 build I'll be using a steel crosman breech and Marauder barrel to build an hpa carbine. I have most of the parts, I'm going to get started soon. Should be fun. My friends chrono reading from yesterday

Your 25 is a pretty cool build, I'm looking to build something similar this winter
