.25 armada journey
« on: June 19, 2018, 06:44:22 PM »
My .25 armada was a sweet shooting gun as it came stock from the factory. But it didn’t stay stock for long. War valve, opened to . .203, .203 barrel port,  44 grain  mds hammer and Tim’s dual wound long spring. I blew several ice maker tubing transfer ports as well as several of Tim hills. I made a brass one from a tubing connector with a oring on top of the valve. It’s about .192 interior dimensions. I achieved some serious efficiency with the valve at .187 and the valve spring fully tightened. 1.9 efficiency on a cold fill and 1.7 several times using 33 grain swaged. I know some have questioned it, and that’s ok, I did too. I didn’t even realize it till later as I have never checked the efficiency of any other gun I own.
I settled on 64 avg for 15-16 shots with 33 grain. 3/4 turn takes me to 985 or so but I like them at 940. The 45 though slower have a better bc down range.  The heavier swaged seem to have a lot of drag in the barrel. I sized the 38 grain bbt hollow point to .250 then stepped down to .249 and got some nice groups at 50 yards. I’m going to do more testing with them in the next week. Not sure where my efficiency is at with the larger port, I haven’t checked, but it i does have a bit more of a peak. I like the ability of this gun to reach out further now with accuracy and a bit more power.

This makes me drool. I've been wanting to turn my .25 Armada into a powerhouse. Unfortunately it's been down a for a while with a leak so it makes it even more close to home to see yours; I'm jealous!

I just ordered new O rings for mine and it will be the first time I've had it apart myself, so I'll probably learn a lot just from that.

Nice looking gun

Thanks! Love this platform, decided to try one more thing. Going to get a marauder stock so I can install my speed dial and see how it tunes out. Once I map it, it should give me a crazy shot count at this power, ... maybe
Leaks are no fun but once that’s fixed you’ll have a ton of fun with your gun. Even stock, I had a blast.
