I always use viton orings if I can. They're way more heat and chemical resistant than butal rubber orings

Anyone shot a 22 Nova Freedom or Seneca Aspen? Feedback wanted please...
- Thread starter WaltherV
- Start date
I have not used the poly orings. The heat range is better the the buna 006 but I made the new seal use PTFE. just cannot put it through it’s paces yet due to no gauge yet. Ordered the right one and they sent the wrong one. But I have the right one coming this week or whenever the slow boat from China gets here. Lol.

Thanks for the input. It's nice to talk to people that actually have good advice! Andrew
Viton and Buna are two of the most commonly used elastomers for sealing applications and for good reason. ... While both Viton and Buna seals both serve as great sealing options at moderate temperatures, Viton is far superior to Bunafor high temperature applications.Nov 10, 2014
I put in the o-rings that came extra with the gun, and what a difference! I also worked on the scope and shroud. I have gone from okay groups with an occasional flyer, to using Sheridan pellets for a target at 35 and 45 yards. I am currently using cast off composite wood flooring with dime size stickers for targets. Two pieces back to back. The Sheridan 20. cal won't go through, but the Nova Freedom blows through no problem. With the Tanto suppressor, all I hear is a loud TWACK. My wife can't hear the rifle in the kitchen, when I'm on the deck right out side. I can hardly wait for the groundhogs to come out to play.

I put a bunch of drops into the pump. Pumped it then put a bunch more and pumped it. Repeat until the pump started to not only pump but move easier. My arms and back were so sore after that day I had to take 2 EX strength tylenols plus some alieve. and still hurt for days after. It's like someone going dirt bike riding for the first time and hurting real bad after because they're using muscles they don't normally use.

General Description: Perfluoroelastomer (FFKM) is a highly fluorinated elastomeric family of compounds that provide the most resistance to chemicals and high temperature than any other elastomer in the market. FFKMs are considered the elastomeric equivalence to PTFE (Teflon) due to its excellent chemical and temperature resistance.

Thanks for the post Paul67. I will only use FFKM from here on out.
DesertSilver, I've been wondering, where does all this extra oil end up going? Blown out the barrel, or lurking in the gun somewhere? I liked the dirt bike comment. I am in the middle of restoring my 76 TT-500. It's a monster.

Pump issues.
I really think they come almost bone dry from the factory (at least mine did) and need a lot of lubrication right off the get go. I have no idea if it made any difference, but this is what I did with mine when I first bought it. I put 6 drops in, then pumped 15 times, then added a couple of drops every 10 pump or so up to full pressure. Then as remembered... That seemed to get the oil into all the parts of the pump. As far as where it goes, I've used about 1/8th the bottle and I have no l evidence of oil leaking out anywhere. The lack of evidence of oil leaking indicates to me that the pump was under lubricated at assembly. Or it's confirmation bias.

S97, I think I will try the saturated pump method, and put in a drop or two as I pump it up from the 800-1200 psi I leave the gun at. I bring it up to 2500-2800 and fire three shots on high (5 shots on low) and re-pump 10 times. Brings me back up to 2500-2800.

If you think that is a monster you need to try my KTM 550 2 stroke .61 hp at the rear wheel. Lol. I'm totally wooped by the end of just a 20 mile ride.

I ve fixed the pumping problem with mine and love it now. It was very dry from the box and just needed a good oiling with the silicone oil that comes with the rifle and no more problems.

Well heck, My Freedom is leaking from the pressure chamber back into the pump tube. If I have it pumped up to around 2600 PSI and let it set for anytime over a half an hour, I fell as if I am going to break the pump arm off trying to open it all the way. Same with closing it.
After a few of these difficult pumps, it returns to normal and pumps up as it should during shooting sessions.
I do keep the pump well lubed with the supplied silicone oil.

My pumping problem is fixed also. Over lubing with silicone oil seems to do the trick. Since "over lubing," I have run close to a thousand rounds through the rifle with no problems. The rifle is too much fun. Definitely my go to rifle!

Hello Android
I'm about to own a Nova Freedom & like what you said about the DonnyFl silencer.
What's on the end of the barrel for attachment?
The parts schematic gives no clue
Also, thanks to everyone as I've learned a lot about the gun in this forum

Go onto donnyfl.com and there will be the barrel attachment you need. Very well made. I would also mod the shroud. I am very happy with the lack of sound while enjoying our sport.

Thanks very much, Android
I'll e-mail Donnyfl now that I know the adapter exists.
Curious to learn more about the 800fps limit on the Tanto
Thanks too for the link to Puric's report at Airgun Warriors.
I am now convinced yesterday's order of the Nova Freedom was a good one.
The shroud mod, other than drilling holes in the bushing has me confused a bit
Maybe I'll understand how where the curlers are used when I get hands on with the gun
Have you tried it?
Thanks again

I shoot JSB Ultra Shocks, 25.39 grains. On high power and the hammer spring turned clockwise one full turn, I approach 40 Fpe, but stay under 800 Fps. UltrA Shock Hollow Points are the only pellet for me. Very accurate and devastating on impact. I believe if you are going to do a lot of shooting over 800 fps, you should go for a different suppressor. Call or e-mail Donny. Very helpful.

I have no burning desire for high fps
Accuracy & impact are the goal.
If the target can get out of the way faster than the 800fps can get there it deserves to live & eat from our home orchad
Silencers are a new twist for us.
I see (assume) now that length & fps go hand in hand
Certainly will e-mail Donnyfl
He just put an adapter in the mail for my CO2 pistol.
Once that Nova Freedom arrives we'll try out those crushers you use, along with the 18.21gr Barracudas I have on the shelf
We will be looking for a good killer pellet; and also a good one for honing the shooting skills without it costing a dime a shot
We (me and Miss 4-11 and a 3/4" ; 98 pounder) are open sight shooters.
Thus the Freedom over the Aspen

The gun you see in the pictures with the curlers, is my Nova Freedom. The curlers with the washers and the drilled bushing work great. I haven't drilled any holes in the shroud, because I am after quiet, and holes in the shroud can make it louder than when you started.
