New Seneca Dragonfly?

[Spacebus]

If I had the mk2 and heard the click from the middle part where metals meet, I might try a little electrical tape there to dampen it.

Looking forward to more experiences folks share as the gun hits the market. I really like the gen 1 and with so many parts in common between the two, more novel solutions for the transfer port issue on the .177 might also appear.

I also have a pp750 and appreciate the value of multiple guns from the same factory in the stable. With a little grinding down of the draganfly mag, the mags become usable for both, which is nice.

CARM mags might be the same for both PP750 and Stormrider/Bandit/Chaser/etc.

I hope when these get in members hands that they are positive. Maybe it's not always just the technical stuff. Sometimes it's the intangibles, ready to scope, self contained magazine repeater, WOOD stock. Hopefully it just feels good?!? Anyway I hope it's a winner

My gen 1 has the point of balance right where the wood pump arm meets the stock. The mk2 will likely have a balance point more towards the muzzle than the gen 1 with the added weight of the metal and larger wood pump arm. I have long arms, wonder how that would be.

I guess my 460 and my k98 would be a similar scenario except my 460 is scoped and my k98 is not.

Interesting. Where would you recommend ordering from?

Thanks for the link!

To work in the pp750 as well, they'd need to be ground down a bit (just like the dragonfly mag did).

Top is ground down except for a small nipple of sorts at the far right.

I had a thought on the DF2....
I'm wondering if it can be tuned to retain enough air after one shot to be able to add 5 pumps to take it back to full power. Kinda like the Seneca Aspen with it's 1800 psi precharged chamber but at a much lower scale.
The claim is that the pumping effort remains the same. My question is... would the power be any better using the upper half of the volume than it would be at the lower half of the volume?
Food for thought.

Interesting... hammer adjustment as a starting point? Never attempted such a tune myself. What might be involved?

[Spacebus]

I think the robust pump linkage on the DF MKII will lend itself to mods better than the c362.

[Keepingitsimple]

If I had the mk2 and heard the click from the middle part where metals meet, I might try a little electrical tape there to dampen it.

Which part of the middle part of the linkage do you think that little electrical tape should be applied to dampen it?

Hard to say, but judging from what I can see in the picture, I might start with wrapiing the middle of the three pieces at the points of clicky contact (should they exist). Then I might try a piece of tape on the outer pieces at points of contact. How dampened the sound of the wood pump arm hitting can become might be a baseline for how audible any other noises such as clicks might be. It's hard to say without one to work on.

PA 25 yard accuracy test:
https://www.pyramydair.com/blog/2022/03/seneca-dragonfly-mark-2-multi-pump-rifle-part-nine/

Top group was AA 18 gr domes which shot a 1.5 inch group at 25 yards.

Looks to me like the MK2 with a red dot sight is about as accurate at 25 yards as a peep sighted Benji 392 using Crosman pellets.

Golly! This thread was down the page a little. Time to bring it back up to the top of the page where it belongs.

Anyway, I had a thought as to the controversy regarding which pumper is presumably better... the 362 or the yet to be thoroughly worked over Mk2 ... so while we wait for PA's 25 yard accuracy test with a scoped Mk2, lets compare something else?

Does Air Venturi plan on offering alternate length barrels and/or is it already offering them in other models using the same platform? Admittedly, this is a gray area for me.

Today I ordered a .22 SE Disco barrel and a Maximus slip on adapter for a 1/2-20 can.

Shortly, I'll be determining the difference in power and hopefully a tad better accuracy as well. I'm guesstimating a conservative 698 fps/15 fpe at 8 pumps for the 24 inch barrel using a 14.3 cphp/cpum.

I think I'm going to like having a longer barreled version of the 362.

The Mk2 with its 22.75 inch barrel might well be comparable to the 362 with a 24 inch barrel.
We'll all have to see later this summer.

Why not post on the Crosman threads? This thread is not about the C362. I also don't think you will pick up any velocity going to a longer barrel, someone already tried, it's on the C362 thread. At least, you won't pick up any velocity with a longer barrel and everything else as it is from the factory. I thought about you the other day when I was making ragged single hole groups with my Stormrider with receiver mounted scope and magazines.

[Keepingitsimple]

Since the pumping efficiency of the Mk2 hits a wall at stroke #10, I'm thinking rubber donut.

Pumps…….Velocity
3 428
4 476
5 518
6 553
7 564
8 583
9 589
10 602
11 601
12 617
13 605
14 617
15 618

Might not be a bad idea for Mk2 buyers and/or users of the MK1 to dump the little rubber doughnut:

Since it appears to affect pumping efficiency.

[Keepingitsimple]

It does appear as though removal of the rubber doughnut in the Mk's is beneficial.

Quotes:
Noticed guys had discovered a governor or controller to over pumping in the form of a little half inch long black rubber link in the otherwise sturdy looking adjustable flat top pump piston/rod with o-ring seal. Possibly Steve W. was first to notice it. Got rid of that and replaced it with steel flat washers!

Before the mod high mid to top end was "getting robbed" - here's 6 pumps shooting H&N FTTs 5.53 14.66 gr. (611 fps MV) and 8 pumps (618 fps MV). After the mod same pellet shoots 650 fps MV on 8 pumps and 675 fps MV on 10 pumps (no residual air in valve). A 21.14 gr. H&N Baracuda 5.52 will launch at 615 fps MV on 10 pumps.

4 pumps mod or not FTTs are hitting 550 fps MV - that's enough to head or heart/lung squirrels and rabbits dead out to 25-30 yds. I've got another little Bushnell 3 MOA red-dot sight like the one I mounted on the Crosman Legacy so soon I'll see what this pumper thumper can do on paper.

A few before and after removing/replacing the "rubber donut" using Crosman 7.9 gr. in a .177 Seneca Dragonfly:

Before 4p = 700 fps MV 8p = 810 and After 4p = 740 and 8p = 865. I think he got closer to perfect in mating or closing the gap between piston face and valve face. I'm satisfied with mine but if I had to go back inside I'd turn the rod adjustment about a half turn 🙂 Heck most of the time using my .22 4 pumps is where I'll "hang out"

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!

[Ronno6]

If the "donut" functions the same as the "elastomer spring" in Daisy rifles, it is a necessary evil as the piston
will bottom out against chamber seal parts. That bumper provides some "give" in order to prevent wear and tear on the other parts...

In fact, the assy shown in virtually identical that used in the Daisy 880 platform

BTW...that donut is preloaded...it requires a sizable amount of force to compress.........
