New Seneca Dragonfly?

[Keepingitsimple]

Interesting doughnut discovery! How did the disassembly process go? Happen to have an after pic to go with the before pic? Thanks for the info on this mod!

The info on the disassembly should be at the 2 links I posted. Not my discovery at all. I'm just tracking down info as always. Doing due diligence.

Originally I posted seeking info on whether AV was planning on offering alternate length barrels for the Mk2 like Crosman does with the 362. Apparently not. That may turn out to be a marketing blunder on AV's part.

I started a thread in the CB gate pertaining to David Grimes of Alchemy Airwerks putting out steroided versions of the 362 in .22 and .177 caliber.

I haven't noticed any 3rd party vendors doing that with the Mk2, have you?

The DF MKII is already using the longest barrels that SPA makes, before that the DF MKI/LR500 were the longest barrels. It's not like Crosman makes any longer barrels for the C362, people are just swapping barrels from other Crosman guns. The one thing I dislike about SPA is the difficulty in getting new barrels. Some day I'd like to make some friends/paid relationship with a machinist who can turn barrel blanks into whatever I need. Honestly, with the exception of some of the high end gun makers and Crosman, it's hard to get a new barrel for anything. It's such an issue that there are even some threads where folks are asking if PB barrels can be adapted to HPA.

Does anyone think the Mk2 would benefit from a longer barrel?

I think it would be beneficial for both its accuracy and power were a 26 inch barrel available for it.

Crosman is working overtime at present pumping out 24 inch Disco SE barrels in .177 and .22.
Doesn't take a brain of Socrates to figure out which rifle they're being put on.

I spent a fair penny on barrels this past week. J/s it might be a good idea if AV did the same thing cause there's gold in them thar hills!

A longer barrel does not automatically mean more accuracy. It can make shooting more difficult due a longer dwell time in the barrel. Generally speaking it is easier to get tight groups with a short barrel, but a longer barrel CAN be capable of better accuracy. It's very likely that the DF MKII has a barrel length that is matched to the valve size, just like the C362. As I said, the DF MKII has a longer barrel than the Stormrider/PR900/CR600 or DF MKI/LR500.

I don't understand why everything is a ^*%$#@ match between the C362 and DF MKII. It's like a Camaro VS Mustang thread.

That's hilarious. It has gone that way a bit despite the original post [chuckling]

Regarding barrel swaps, my PP750 is leaking slowly and is due for a tear down. I wonder if I could swap that pistol barrel onto the original Dragonfly for a weekend just to see what happens in accuracy and power with one and two pumps, which is how this gun is most often used at my home range.

My .22 SE barrel arrived yesterday. I swapped barrels and immediately noticed more pep to my pumps and better accuracy than with the OEM 21" barrel.

My .177 SE barrel will be arriving today so I'll be swapping barrels again.
The .177 barrel will likely stay on it for awhile.
.177 362's are turning out to be real sleepers.

I put a 16" .25 cal barrel on my Storm rider and lost a small amount of power, but more than made up for it with a vastly superior BC. 8-10 MPH breeze made no difference in POI at 25 yards with just a front end rest (still a bit shaky) using H&N FTT .25 cal. It also seemed like I made peak power at a lower regulator setting, but more testing will be required to know for sure. Just waiting on an LDC right now otherwise I would be up in the attic testing today!

[splitbeing]

Nice! Keep us posted on the attic test!

I did get up into the attic today and tested even with the loud muzzle report. I was getting 675 FPS average with the 20.06g H&N FTT and 550 FPS with 30.86g H&N Barracuda, so about 20 FPE either way. I was getting a bit more power yesterday while testing with the H&N Crow Mags, but I'm pretty sure I was getting some "reg creep" from air getting around the regulator. With the exception of a bit of lead in the back of the hammer, a Huma plenum sleeve, the Altaros reg, and the obvious .25 cal swap I'm all stock. With the 3" longer barrel and 20 grain .22 cal pellets I was sitting at 27 FPE. With a full length .25 cal barrel I'm confident these guns could be making 30+ FPE in .25 cal. I'm so tempted to get a second .25 cal receiver for my Bandit, but I think long term the Bandit will end up unregulated with the 16" .25 cal barrel and I'll live with a .22 cal Stormrider. Then I'll have a 20+ FPE bandit and a near 30 FPE Stormrider.

Eventually I'll have to get a DF MKII even if just for the longer barrel.

[splitbeing]

Any hunches on most accurate pellets with that configuration?

I should really make a new thread, but nobody seems to mind.

I assembled the Bandito .25 long barrel unregulated and tested H&N FTT 20.06 and Hatsan Vortex Strike 24.70 for accuracy. Unfortunately I shot my chronograph before testing the long barrel but I have a 195b down to 90b shot string for the "CO2" spring and the "HPA spring" shooting the FTT's. The short barrel peaked at 547 FPS at 95b with the light spring and 635 FPS at 140b with the heavy spring. I am betting the long barrel will boost those velocities by at least 100 FPS, but I won't find out until my replacement chronograph gets here. With the short barrel and HPA spring the Bandito is averaging 17.5 FPE for six shots. I estimate 20-25 FPE with the long barrel, which is wicked out of a PCP that can fit in my backpack with the LDC and stock removed. Eventually I'd like to figure out a shroud with built in air stripper.

There was a serious 15 MPH wind with even higher gusts that had the trees dancing, so groups were variable. In breaks from the wind I was getting 1/2" ragged hole groups with the H&N FTT and Hatsan VS pellets using a front rest and red dot sight from my crossbow. My testing in the attic at 30' yesterday was with the same barrel and receiver on my regulated Stormrider and the groups were the same size with no fliers. I was impressed with the Hatsan pellets most of all. The groups were tighter even with the wind, but not as flat of a trajectory. This setup might even be good for 50 yard shooting if you can deal with the loopy trajectory. My plan was always to use it at 10-30 yards.

I plan on casting some 34 grain pellets for my Eagle Claw and will try them in the Bandito as well. Ultimately I want to cast those 34 grain pellets in pure tin and see if they are as good as the H&N Barracuda Green 19.91 grain pellets, which is exactly the weight I'm estimating for the NOE pellets cast in tin. They are "minute of vermin" accurate out of my Eagle Claw at 25 yards, I would be happy with that same accuracy at half the FPE out of my Bandito.

Also, I'm glad someone wants to hear about this. I'm pretty stoked at how well my little Bandito has turned out and my wife has zero interest in hearing about it 😂

I really want to make the NOE wadcutters work, but I need a working chrono so I know what speeds they like. I'm betting with the short barrel and CO2 spring I can get the velocity down enough to make them work, or I can try casting them with the shorter mold pins to get them a bit heavier, I've only tried the longest pins.

I just got another new chrono and am thinking, "At this rate, does buying two at a time makes sense?"

How far down in fps are you thinking to get them working?

I think the NOE Wadcutters need to be going less than 600 FPS, probably closer to 450-500 FPS to be accurate. I want to try casting with the longer pins and get the weight up to bring velocity down, so I can keep making at least 17 FPE.

My chronograph is dead, but I got the .25 cal NOE wadcutters to give me quarter sized groups. Even with 10+ MPH winds I was able to get acceptable groups. I used pellets cast with the shortest (not flat base) pins and mid length pins, but the heavier pellets were more accurate. Cast weight for the short pins was 24.5 grn and I used the CO2 spring, short barrel, and filled to about 110b to keep the velocity within the "sweet spot" for six shots. I'm waiting on another Altaros regulator and plan on seeing if I can get a higher number of consistent shots per fill. With the CO2 spring I'm making peak power down at 80b or so. Above that you don't even need ear pro. From 200-80b you can get a nice vertical line if you are steady and there's no wind.

550 FPS seems to be about as fast as you can push these wadcutters. Based on my testing with the Crow Mags the WC's should be traveling at 525-ish FPS for about 15 FPE with my fill settings. Even with the lower velocity I look forward to when my LDC and adapters get here and all I will hear is the hammer hitting the valve.

Glad you got them workiong, I had NO luck at all.

I suspect you were trying them in you DAR which is sending them wayyyy too fast, my Eagle claw was doing the same. I had a hard time keeping them slow enough to be accurate, but fast enough to not have a rainbow arc at 10 yards. Below 400 FPS they just bounced off of my cardboard box packed full of magazines, but I have taped over it many times to keep shooting it.

[Firewalker]

Yupper, I stopped at 600 fps since slower meant less energy and short distances.  .25 for me is the distance gun. .22 is short to mid range.

I want all of the .22 and .25 pellet molds, right now I'm up to three out of six. I'm only shooting the Bandito at close range and plinking, and it's pretty quiet without a moderator at the low power needed for those .25 WC's. I have the Stormrider .22 for 25-50 yards and the Eagle Claw .25 for 50+ yards. My .45 does great at 50 yards as well and that's what it is zero'd for right now. I have a feeling the Eagle claw will be more accurate out at 50 yards with slugs than it is at 25 yards. Before my scope problems it was making one ragged hole at 50 yards with NSA slugs.

I ordered the DF a couple of weeks ago.
At that time the ship date was 5/11/22.
Now I see it has been pushed back to 6/13/22.
PA charged my card when I ordered............
