Any US importers carrying this gun?

Billy: Many thanks!

Once you've had the reg off/out, you'll realize it's almost impossible to bottom out the poppet valve. Eventually you just shim to the point that the sear will no longer engage with the hammer.

Interestingly, I do think that with the hammer shimmed to the max, and the reg set close to 200bar, this rifle might just throw 14.3's hypersonic...

Yeah even after I doubled the pre-load on the hammer it still cocks pretty nicely. I’m going in for a half day today at work and I’m going to try and get some chrony results later this afternoon hopefully.

Well the weather man really blew it on the report for the Nashville area today, was supposed to have sunshine but instead, I've got overcast skies and snow falling. Might make chrony testing outdoors a little tough later, but at least I can still shoot from my family room window. Bet they didn't see this coming.

I did not know that as I have not gotten that far in yet, thanks. Looks like more shims today!

Hoooraaaaay the sun came out and the snow stopped, will wait for things to warm up a bit before venturing out with the chrony. I did take some time to shoot a few groups this morning already and have a new observation concerning the mags. As so many others were getting decent groups with the CPD's I decided to try an experiment. I've noticed that the spring tension in the factory mags is stronger than it is on my Marauder mags so I loaded the CPD's in one of each and checked group sizes, the pellets shot better when loaded from my Marauder mag, much better. I'm going to try the same test with some other brands and see if the same thing occurs, if it does I will open the factory mags and see if I can reposition the spring so it has less tension when fully wound. I may try the single shot tray and see if the groups shrink also. The weather isn't ideal today, although the sun did finally come out the wind has also come up and will make the groups open up a bit. I'm still shooting at a lasered 35 yards and if this were a spring or gas ram gun I would be happy with any of the groups, the barrels on these really aren't pellet pickey as already noted. Just looking for the magic pellet like we all do.

I'm still trying to figure out why these guns are so quiet? My outlaw has basically  the same set up but it was so much louder that i had to get a moderator on it quick or wear ear plugs. The liberty has a solid collar with 2 o- rings about 4 in. from the muzzle that centers the shroud. I wonder if moving the position of that collar would affect the sound? When i get my end cap back it might be worth a try.

Pat have you tried this yet?

I do not know a lot about the workings of shrouds but it seems there should be some holes in that collar to use the entire space of the shroud.

Any opinions on this theory?  Drill holes?!

[USAFANG6799]

Tom: Your findings are are very similar to mine. I’m a bit confused with mags and single shot tray so still trying to figure things out.
My Marauder mags were fitting looser than the Liberty but figured it was because they had more usage. I did put a little silicone grease on the Liberty mags which made them fit easier.
Not getting any jams using various pellets on Liberty mags or Marauder mags. But still have more pellets to test.
Single shots using the H&N Terminators are in single hole at 20 and 30 yards.
Can’t be happier.
Outside noise is better than expected. Think as good if not better than Marauder.

Ray= I haven't tried it yet because i sent the end cap out so i could get an adaptor made. When the adaptor came back i just put a donny tanto on & it's super quite now. As for my .177 i should be getting my crosman baffles today & will see how that works. It would be a good experiment to try drilling holes in that bushing. I don't see how it could hurt! I was also thinking of moving it further down the barrel to get more shroud space?

[pat585]

Tom= I have been doing some shooting with all my rifles in the basement. The only guns of mine that shoot one hole groups are my nova, wildcat & my prod. But the prod has a huma reg & a MM barrel in it. I just target shoot so i use the single shot tray in my nova. This one hole accuracy in the nova just blows me away!!

Just came in from outdoors, finished chrony testing for today, fingers still warming back up. Only tested three pellets weights to get a cross section of FPE and speed. CPD's were giving me about 25.5 FPE, JSB 18.13's were just hitting 28FPE and H&N Barracuda Match 21.14 were giving me 31.8-32.2 FPE. Still need to order some JSB 15.89 to try as suspect from youtube they may shoot best. I'm not unhappy with the groups on the JSB's or H&N's, but the CPD's even when shot with the single shot tray just threw to many fliers. What's odd is the FPS was the most consistent on CPD's but not group size. H&N sniper magnums were better than the CPD's and the polymag shorts were awful, only shot about three pellets and they scattered like a shotgun at 35 yards. Now the question is do I want to shim the hammer spring to bring the JSB's above 30 FPE or just wait to get some 15.89's before digging into the rifle. The 21 gr Barracuda group nearly as well as the JSB's at this point and hit the target in nearly the same place, no scope change required, may just leave it alone for now and let the regulator continue to settle in. You others with 22's, what has been your most accurate pellets so far, 20 yard groups don't count.

Hi  there airheads!,, anybody willing to make video showing how to shimmering the hammer?

[Fwawa20]

Tom- As pics earlier in the thread show at 50 yds 18.13. Mine actually shot 18.21 H&N Baracuda hunter hp really well out to 30 yds as well. After that they opened up. I’m going to try the redesigned heavies at some point after I get the power to where I’d like it to be.

There iare pics earlier in the thread. I removed mine and shimmed with additional washers. I degassed completely dry fired twice to make sure there was no air remaining. I then removed the stock and knocked out the pin that holds the spring in place. Hammer spring popped out and I added 2 washers with lithium grease and reassembled. It’s that easy. Takes less than 5min.

Tom= I know 20 yds isn't much. I used to shoot my benchrest rifle at 300 yds. My reasoning is if my gun  can put 5 shots in one hole at 20 yds how bad could   the group open at say 40 yds? A lot of my pcp's shoot nice round groups at 20 yds but only a couple put them in the same hole!

Tom,
Odd. Both my .22 barrels love the CPUM's. If I'm doing my part, less (sometimes a heck of a lot less, depending on the wind and how badly the arthritis is acting up) than a dime at 30 to 45yds.Lasered. Same for the JSB 15somethings. Not-so-much for anything else. Not bad mind you, but not "WHAT?!!! Did they all really just go in the same hole?!!!" good. This is with the hammer spring shimmed at 3.58mm.

I shoot standing/leaning in the bed of my old crew cab F-250, off of a bipod and rear bag on the roof, at the whitewashed side of one of my old Steer pens. I fire a shot, then zero to that same point of impact. No-name (cheap and Chinese) Amazon 6-24X40 ao scope.

How clean is your barrel? I ask because I simply could not get a patch to come out clean on either of my barrels. Even with the barrels removed and using a bronze brush and #9 bore cleaner. I actually wound up using the above, plus a nylon bore brush and chlorinated Brake-Kleen to finally get the job done. Oh, and I should mention that I had the cleaning rod with the nylon bore brush chucked up in a cordless drill.

One thing I have noticed is that the bores on these rifles are tight. And the lands and grooves are really shallow. Almost like they were etched, rather than cut.

[tracker1955]

As I mentioned earlier in this thread, I used an industrial degreaser to clean the shipping sludge from my barrel, didn't take very many patches before they came out clean, then ran some dry patches through to finish. As much filth that came out for some of you it was as if this barrel got missed with the heavy dose of protectant from the factory. I do need to devise an easy way of feeding my pull through down the barrel since there are no baffles to guide the straw in on like on my Marauder. I have an idea for it, just have to get the materials from work to put it together.

I used frog lube degreaser and a kite tail.. A couple of runs and clean...

Thanks Frankie I’m gonna take a look!!

I hope someone does a video of a complete tear down.. Mostly the regulator and trigger..
