First FX Boss with a 500mm stx?

Got this 500mm barrel house from a member here AR, fellow Canadian. It struck me yesterday that I've never shot it in .30 so I filed and sanded down the area that enters the breech.

And had been sitting on a Boss .30 probe and bushing so put it all together what a compact package! So now I can use my 500mm .22, .25 and .30 from this barrel house and do the same on the Impact when I want.

Super light!

Excellent project and very good looking "compact BOSS". Probably the first one!

Now this maybe the first FX ELITE with STX barrel system. I used stainless steel tube 14 x 2 for the barrel housing and a friend of mine machined all the parts.

I like it. It looks amazing. How does it shoot in. 30?

I havent shot from this gun other than a few inside but I've used this setup from the impact and it shot very well. It's a Pellet A liner that's been cut down

Beautiful gun there Costas

nice job on the barrel and the C/F bottle Glem

Appreciated Sonny

Glem, you better head to the woods to fire that 30 off!!!

jk

I will first chance I get, was slaving this weekend to pay for toys haha.

That looks great!

Appreciated Dallas!
 
Glem, I WANT!!! How can I do the same to my Boss? Cost (approximately). Is yours capable of shooting slugs now? If so, results? Man, you've got me curious & itching to spend $ I don't have! Any changes in accuracy or distance capabilities?

Just need a smooth twist x setup and a slug liner if you want to shoot slugs. The rest is just a bit of work and you'd use your Boss brass inlet. 

I'd say for the Impact would be best as the shroud would work kind of like my pic. Whether they fit the same on the aluminum bottle the same I'm not sure.
 
The FX Bosspact looks great Glem. Gotta be lovin' some FX about now.

Thanks very much TT, yeah I really love how so many parts work cross platform with FX. Swedish Lego for men.

Subaru is very much like that also, I have a first generation forester turbo from Japan and I've put all kinds of parts from different subarus on it. It's a little ripper for sure. 

Did a bit of testing after work to see what it would make with the reg pressure its currently set at. I'm pretty sure its in the 155 range. Made 75fpe with 50gr with the hammer spring maxed out, and 445fps with the adjuster backed out flush with the block. I'll hopefully shoot it this upcoming weekend and see where the reg is set. But I seem to remember 150-155 on the huma as it was set for the 600mm lw to shoot slugs pretty hot.
 
I've always admired and wanted an FX Boss, but the specs were too low in power, and I didn't know if they could be ramped up or not, same with the Impact. When the PP kit was introduced, that was all I needed to see and picked up the Impact thinking more options with that platform, so the Boss never happened for me, but still I like it a lot.
