That's great! I too am going to get a .22 barrel for mine eventually such a versatile platform can't wait to see how the .177 does!

OK ... we have some photo's ....

As delivered it is set up with a Lefty breech ... tho will be ultimately using a Righty so a large side focus wheel can be fitted.
Optics chosen the BSA Tactical 4x14-44 FFP on med Hawke rings.
Stock a fixed length ( Tho it can be cut shorter & will be ) utilizing a FOLDING hinge so compactness is excellent !
Shroud as shown is collapsed, tho does pull out @ 4" allowing the supplied baffles to be inserted.

Little bit of internal fiddling last night we have it running at a lighter power setting of @ 15 ft lbs tossing JSB 8.4's @ 875 fps and the Heavy 10.3's @ 820 fps.

We're currently using a valve that's ported very conservative and will in the next few day being utilizing a WAR valve set that should really amp up the juice to pellet.
Ideally wanting to see @ 18 ft lbs ( 10.3's @ 880 )

BTW were working with just 12" of barrel here on the WARP ... so it barks pretty good at this power level shooting w/o shroud out and no baffles

Thats it for now as we go about massaging the internals

You should try a more vertical grip, I recently got one of these: http://www.larue.com/larue-tactical-peg-grip

Ok .... first constructive TUNING update and a recoup

Warp carbine with a Ninja regulated 13 cu in bottle set at @ 1800 psi.
Barrel a 15mm Lothar Walther at @ 12" length

After changing the WAR valves internal seat to one a tad smaller, manufacturing a special shape transfer port while retaining the factory hammer & a soft hammer spring ...... BOOM !!!! Massive power on tap

Starting with hammer spring tension backed nearly all the way off we were seeing mid 600 fps range with JSB 10.3's

Within 3-4 turns of increased tension we went past 900 fps ! and within a turn more we were @ 1040 fps and still had more tension available. At this juncture did not even check to see whats left ? ..... thats for another day with some HEAVY .177 pellets

FYI ... 10.3 grains at 1040 fps is just shy of 25 ft lbs !!! .... beast is right and darn impressive out of just 12" of .177 cal barrel on 1.8k pressure.

We backed it down to shoot the 10.3's @ 900 fps and now the actual IN FIELD testing begins

Wow! Scary numbers. 25 ft lbs is incredible.

Nice work, Scott.... Dial that back to <20 FPE for FT and you should get a ton of shots....

Once you are done tweaking and tuning Travis needs to offer a .177 kit with all the necessary mechanicals and tank for us .25 WARP owners. Talk about versatile I already asked about a a .177 barrel swap out for the one I have coming in a few agonizing days of waiting.

Subscribed and looking forward to seeing your results Scott!

Bit more fiddling done earlier in the week.
While previous set up made BIG power was not real happy with the firing cycle when hammer tension was backed off more. Felt the "Lock time" was too long and general feel was sluggish with the heavy OEM hammer getting cycled with a soft spring

So .... decided to revisit manufacturing of a Light weight hammer that would have lower friction within tube, accelerate quicker and speed up the lock time considerably.

Went about using a similar design used before having a body of MDS nylon back weighted with aluminum.
Also made hammer have a nose to de-stroke travel some.

Back together again with the same light hammer spring used previously the shot cycle now MUCH FASTER with much increased SHARP SNAP muzzle report over the previous Snap of a longer dwell cycle.
Over the chrony with 10.3's and we're seeing @ 880 fps with some spring gap still present.
Tightening up hammer spring preload into compressed state only gains 15-20 fps.
So with this weight of spring ( Pretty light ) and weight of hammer of @ 50% of the OEM were still making 98% of the power we wanted. * This 10.3's @ 900 fps

Pellet loaded the gun is substantially quieter than previous configuration & shot counts getting better too.

2 entirely different tunes that shot @ similar velocity, tho had completely different feel to them.

What we're finding is that the HEAVY BREATHING attributes of the WARP really can be mellowed out making a sweet small bore .177 purr like a kitten.

Rains here in force and been wet all week !! with no let up forecast well into next week

Need some chrony & target time now !!

Ok guys here is my take on this platform after shooting the one Scott is working on.....

I WANT ONE

Nice shooter, accurate, and compact.

Unbiased, and unasked for opinion.

Had to do some quick thinking myself with two weeks of downpours and no relief in sight. My pirate ship door is in full effect

Motorhead · « **Reply #31 on:** October 31, 2016, 04:33:39 PM »

We made a handle for a more comfortable grip in ALL shooting positions ...
Added a telescoping '"Antenna" for a wind flag ...
Added an adjustable Butt plate / pad ...

We're getting closer to a rigged FT gun making it very close to some actual in field FT trials

Tomg · « **Reply #32 on:** October 31, 2016, 04:54:15 PM »

Hehehe, love the antenna:-)

Motorhead · « **Reply #33 on:** October 31, 2016, 07:20:25 PM »

Just a recap ....
WARP carbine with a .177 cal 12" barrel, BIG valve, 3K fill @ 2K Reg set pressure, 13 cu in (213cc) bottle, Crosman 10.5 heavy pellet.
Data below shot with the Light hammer & Tapered transfer passage.
Outside air temp @ 57*f Humidity @ 82%

870 864 867 862 874 873 872 869 870 865 / 859 863 863 862 863 862 864 863 867 862 / 869 865 865 860 862 862 865 859 864 862 /
866 865 866 868 865 868 863 874 864 872 / 867 869 866 865 860 864 868 868 867 859 / 869 865 865 869 869 871 866 868 868 869 /
869 873 875 874 867 871 874 876 874 874 / 877 883 879 875 877 877 879 878 875 879 / 876 873 873 866 867 867 872 872 856 854 /
848 845 845 841 838 837 830 828 823 824 ..... 100 shots

Looking at on gun pressure gauge it came off the Reg @ shot 65 ( Start of BOLD numbers ) went up in velocity just a tad as it enters the tail end of the unregulated bell curve and is back at average velocity by @ 84 giving @ 20 more shots under self regulation with just a rise of @ 10-12 fps over the 65 preceding shots ... DANG

Efficiency per Lloyds calculator the first 65 shots at 1.28 using @ 15 psi per shot.

While the efficiency is not stellar

it is pretty dang good considering the power we're at from just 12" of barrel .... IMO

Thats all folks !
Scott

Tomg · « **Reply #34 on:** October 31, 2016, 07:28:44 PM »

From a 12" barrel that is just awesome. Good job!
Keep us posted, the want is strong with this one...

oldpro · « **Reply #35 on:** October 31, 2016, 08:10:54 PM »

Could you imagine if we put the 480cc 3700psi bottle on it!!!!! You would need a 8 hour day to shoot a shot string LOL

Motorhead · « **Reply #36 on:** October 31, 2016, 08:47:51 PM »

Weather calmed down ( Wind ) so we shot a couple targets.
10 shots each at 30 yards using Chrony pellets ( Crosman 10.5's ) and KNOWN accurate AA 10.3's

YES, that's 10 shots taken off a bucket & shooting sticks at 30 yards

Looking like the WARP .177 is indeed worthy

How much work is required to swap to a larger bottle ?

Rallyshark · « **Reply #38 on:** October 31, 2016, 11:12:24 PM »

Considering the 12" barrel, that is pretty good efficiency! Nice work! With the big bottle, you could shoot forever, before needing air

oldpro · « **Reply #39 on:** November 01, 2016, 11:30:19 AM »

The carbon bottles are $190 and takes less than 5 min to put on.
