Love it Dan.

I do believe the 1.9 efficiency and show should everyone else. The combo in your your gun is very similar to Aceflyer and mine when I was running .187" porting.

The great thing about the spring is just a turn of 1 screw ( and nice mod you did to accomplish that on the Armada ) and you can get what ever power range the gun has with a great efficiency.

I do like the comment about the cocking effort too. It is so hard to get past people the this "heavy" spring ain't so bad. What people don't understand is we are not compressing the spring like a standard pre-loaded spring. At 2" spring length, it's only 8lbs to 12lbs max cocking effort with the HS set from 0 to 4.

Happy for you and keep it up.

You know,
The next cool thing to come is a 24" barrel and custom baffles and use the stock length shroud. An extra 4" on the barrel will give even higher efficiency and power level.

You got to know that I am working on an affordable barrel (slug and pellet) and some 3D printed baffles to keep it quite. All this slug testing I am doing?!>:

Something interesting is coming. Told you I have half of December off. Just can't sit on the couch and watch TV all day while the kids and wife are at school.

Some say 10fps per inch after our 20" barrel

Thanks Tim, man I love that spring. It is weird that it's not hard to cock and yet takes so little to raise the power. I noticed that my shot string fell off earlier today after filling with the pump from the 2k mark. I was in a hurry and really got my pump hot as well as my air tube. I'll fill it and let it set, then if I need a bit more air it shouldn't heat up. I did it tonight and I lost 100 psi after it cooled. But all in all, I'm really happy with all the mods I've learned here. Every mod brings a little better power and efficiency. I'm looking for a place to extrude hone my valve and final polish the inside, blocking off the seat though. Talk about a smooth air flow! Also extrude hone the tube, while protecting the fill threads. That will eliminate oring problems and the smoothest hammer action available.
Keep the ideas flowing Tim, everybody benefits!

it is sort of a sling shot effect , the rubber never is stretched in the forward postiion with any preloaded energy release.

Continuing here, maybe this thread will help someone else in the future. I opened my port and my valve to .203. Left the hammer spring set at the original setting with a 1/16 gap between the hammer and stem. Filled to 2900 and first shot went 977 with 33 grain. And then my chrony went dead. I’ll back up the hammer a bit and may have to tighten the valve spring a bit. I loosened it 2 turns to make it a bit easier for the mds hammer to open it and get a bit more power on 45 grain slugs. I’ll air up, get some new batteries, and try again tomorrow to get shot string from 3k at minimal settings.

More testing with the .203 port.
33 grain, 3k, 16 shots, 940 average 64.7 ft lbs avg.
45 grain, 3k, 13 shots, 841 average, 70.65 ft lbs average.
Will easily push the 33 over 1000 FPS and the 45 over 900. More of a peak with this size port, a bit more air usage, easy power. I can reinstall the 187 port, choke it down and lengthen the shot string at a bit less power. I have yet to adjust the valve spring in a turn. That’s next and go to 3100.

oneshot61 · « **Reply #86 on:** June 19, 2018, 09:45:37 PM »

The numbers above are with a Hill transfer port. I think the inside is .190? I collapsed another one so I bought a brass 1/4 inch tubing connector, turned it down on my drill and a file till it fit the breech port. Opened the inside slightly, at about .192. No more collapsed transfer ports. I like where the gun sits power and accuracy wise at 62 -75 ft lbs , with the 33 and 45 grain swagged and may try some 37 and 39 for kicks. I actually tried some of the bbt 38.5 hp and when sizing down to .249, I got decent accuracy at 50 yards. I think weighing and sorting now is the key for those. Efficiency is good and will be a bit better when I tighten the valve spring one turn. It’s been a nice journey modding this gun and for now I’m going to leave it alone and just shoot it.

That’s awesome, Daniel. I am envious, not gonna lie there, on your results

Thanks Augie, but I have to say, I’ve learned almost everything I know from the guys here on gta. There are some fantastic minds here.

Color me impressed! Good work Sir!

Extrude hone. Good stuff. Did wonders for the GT-40 intake! Especially the lower.

Thanks Michael!! It’s been a lot of fun. I’m still looking for someone to do some honing for me. Probably would be cost prohibitive for a custom gun dealer to set that up, but for a gun that’s going to be a keeper, it would be worth it.

triggertreat · « **Reply #91 on:** June 22, 2018, 12:27:53 PM »

You sure are kicking out some good power with that Benji! I still have a few of those slugs you sent me and haven't forgot about them. I have a LW tube and a SS tuning kit and am planning to enhance both of my two guns soon.

oneshot61 · « **Reply #92 on:** June 22, 2018, 03:02:52 PM »

Thanks Keith, I got a good one for sure! Your going to love those 33 grain. I think the key is to polish the barrel including the choke. What’s in the tuning kit? You already have the valve in...right?

You can see a picture of the kit on JSAR. It has a lighter valve spring and a different jet for regged tunes.

I forget who you got those 33's from. I cleared out my inbox back when admin requested we do so and lost our communications on that plus all others. I wished now I hadn't done that.

oneshot61 · « **Reply #94 on:** June 22, 2018, 05:17:18 PM »

Pm sent. Checked out the kit, that’s pretty cool. Should be able to tune to almost anything you want.

Yes I am looking forward to getting back into both of them. The 22 is getting the LW tube and a retune and the 25 is getting a air leak fixed and a retune. Too hot to shoot much, but I'll dig back into them soon. I got a few other parts too.

KnifeMaker · « **Reply #96 on:** June 22, 2018, 06:54:51 PM »

Dan, I forgot about those slugs. Didn't shoot well for me at all. However, I have upped the power quite a bit, and I do have 5 of them left. I want to see if the higher fps can help. It was only in the low 600's when I first tested them.

Have you considered calling Extrude Hone themselves. I remember they use to be easy to work with, just expensive.

I have not. There is a gunsmith in Columbus ga that is going to install my .257 barrel on my Cothran. They have a contact in Atlanta to do it for me. (Extrude hone)..I’ll get more details on it next week from them. If it works out, I’ll do my armada valve and tube.

I missed this... which ones were you shooting? I can’t remember if I sent you any🙄.
