Bottle conversion on FX dreamline classic

Thought you folks might be interested in some modifications and groups I've shot with my .177 FX dreamline. I already put an extra power hammer spring in it and have a heavier hammer and heavy slug barrel on order. The oem barrel does not group slugs good enough for long range shots on appropriate game.
The bottle conversion required a new regulator, it was difficult to get it exactly where it was set before but I got it close on the second try.
It's now getting 923fps from the 16.2 gr pellets, 981fps from the 13.43gr slugs and pellets and 1081fps with the 10.34 pellets.
Both the 10.34gr and 13.43gr pellets grouped well at 50yds but the 10.34 ones were very slightly breaking the sound barrier and not silent, no bueno.
I shot both the Hades and Heavies in 10.34, I mismarked the target, that center top group is actually a 10.34 heavy pellet.
The 9.57 H&N clocked over 1100fps and sounded like a 22lr, too much speed with pellets and your suddenly shooting a shotgun.
The 16.2 gr beast pellets become unstable somewhere between 40 and 50yds, as in the last range session they grouped really good at 35yds, today with the little bit of extra speed they were right at 1/4" for 13 shots, impressive. It's a shame they don't hold that level of accuracy out beyond 40yds.
In general the groups are pretty good, sometime in the next couple of weeks I hope to be able shoot some groups in one of my customers barns which is over 50yds deep to see how well they group without wind.
No doubt that the 16.2 gr. pellet is my first choice for putting down large small game because the shots are rarely over 20yds, remains to be seen whether the 13.43gr or the 10.34gr pellets are the best choice for longe range pigeons, squirrels and pd's/rats. The heavy slug barrels seem to be taking forever to make it to the U.S.


 
As far as the tuning goes a lot has happened in the last 6 weeks, I tried a heavier hammer weight which didn't do anything for speed and put a new scope on the gun. Also fine tuned the regulator pressure and hammer spring adjustment to get 992fps with the jsb 13.43gr slugs.
I've shot 4 raccoons at work, the first 2 with the 16.2gr jsb pellets and the last 2 with the 13.43gr jsb pellets. Not a big sample but the lighter pellets seems to put them down faster. I also bought two of the FX 500cc aluminum/steel bottles, that should eliminate the need to drag my compressor to the range or just out shooting anymore. Those three bottles combined could go 225 shots, that's alot of shooting, also picked up two extra magazines. I accidentally discovered that the 30mm rings for the new Hawke 6-24 compact are high enough to allow the use of the factory magazines.
To vetmx, I have no need or desire to shoot the gun detuned and the weight or length of the gun isn't an issue in my shooting. The power wheel is my go-to in attics and crawlspaces.
If I feel the need to shoot a less powerful gun I've got a new Weihrauch 97k.

Hi, a Kiwi Dreamline Classic owner here. This is one of several that I own and I like the gun very much, it's my primary target shooting rifle. The only thing that frustrates me with it is the small air cylinder capacity. I could upgrade to a Crown but I don't like the stock on that gun so I'd rather increase the air capacity of my Dreamline by fitting a bottle. I can source the bottle conversion and power plenum parts for the standard Dreamline easy enough, but apparently they don't fit the Classic. I'm not sure if it's just the stock (mine is the synthetic version) or there are other complications.

This is the only conversion info I've been able to find so I'd really appreciate your help in terms of specific parts used/replaced and any other changes you made for your conversion. I'm OK to modify my stock or purchase another to do the same. Cheers.

Not sure what that part is called but it's the one at the bottle screws into came from a chassis gun parts list. I believe that was the only part I had to buy, because it was a wood laminated stock I did quite a bit of woodwork to try and make it look good and be robust enough to use in a field. I still use this gun all the time at my Pest control business shot a bunch of pigeons the other night with it turned down to level two. It's gotten a real workout this summer shooting at a horse boarding place that has a huge prairie dog population, shot several at really what I would consider crazy distances for a pellet gun. Several at almost 90 yards, that's using those hollow point slugs 13.43 grain jsb
 
My only issue with the gun is that the bottle is exposed without a support on the underside of the forearm if you have synthetic stock you could build a picatinny rail for end to put a bipod on or just rest the gun on instead of resting it on the bottle. In other words make a forearm where there is no forearm, pretty tough to do with this laminated Woodstock but with a synthetic stock and screws epoxy you could probably do it with a little bit of creativity
 
Thanks for the really quick response.

Is this the part - the FX bottle adapter?

The exposed bottle will be no problem as I only target shoot with it bench rest supported on leather bags. I'm about to remove the stock and see how I might be able to modify it to suit.

bit of entertainment from gilles
 
Thought I'd post a pic of my conversion. It was very straight forward, I just had to trim the stock back far enough to get clearance for the bottle conversion and power plenum. As you can see the bottle is a 500cc Tuxing item. Apologies for the messy bench :sneaky:

Looks awesome! Great job! You wouldn’t apologize if you saw my bench. 👍🏼
