Beeman  Some 97K tuning experiments.

Experiments because I haven't done this before and I don't have a "milling machine", but I do have a very rigid drill press and a lathe. But I wouldn't recommend doing it this way because it was a PITA, but I managed to make it work.
I'm talking about buttoning the piston and compression tube on my 97K, which I've been contemplating doing for some time.
I started out by truing up the runout between the piston head and the piston body on the lathe which wasn't much .003" radial and .002" axial, probably doesn't matter, but I did it anyway. Then drilled the blind holes on the drill press 140rpm using a 3/16 carbide, 4-flute center cutting end mill

.This was set up as rigid as possible, being as close to the stubbed up end mill as I could, only having to feed the quill down less than a 1/2", and my drill press will go down to 140 rpm's, which I used. Only drilling about .025" deep, I have a indicator rigged up for a depth stop.

Two buttons on top and four on the bottom.

Next I made the buttons on the lathe for a snug fit and super glued them in place. Then dialed the piston in with the 4 jaw chuck and turned them for a slip fit in the compression tube.
IMG_7399.jpeg

Piston came out good with a nice sliding fit in the compression tube, now the piston will stay centered in the tube.

Now for the compression tube. I had heard that it was case hardened, but it wasn't as hard as I had thought it might be, and no match for the carbide end mill. I did go slow with it though. Before I started, I machined a delrin plug for a snug fit inside the compression tube, and this I think, helped with the rigidity when buttoning and when chucking in the lathe to turn the buttons.

I put four buttons on the top and four buttons on the bottom, machined them for a slip fit in the receiver. These next pictures are where I have already applied the Krytox lube GPL223 on the piston and compression tube, so you can see how little I use on them. This is the bottom....
IMG_7412.jpeg

And this is the top. I have blued the front portion that will "show" when it's in the receiver as well as the face of the compression tube.
IMG_7411.jpeg

I also machined a new oring piston cap with the trued up piston so it's all concentric less than .0005" and installed a new Viton oring.
IMG_7413.jpeg

I'm still using the old JM QX4600 spring with my guide kit that's spaced up to max, it has thousands of shots on it and still going. Assembled it all back together for testing.
IMG_7415.jpeg

IMG_7420.jpeg

Initial impressions, I like it. Cocking is smooth with no play, a lot more solid when closing. Just seems more solid all around. Of course it will break in over time. I assume the oring piston will also break in over time and speed up some. I only shot a 100 pellets today before it started raining again.
These are the first shots at 40 yards benched, all 10 shot groups, shot in order 1 thru 5.
IMG_7427.jpeg

After the 4th group it started to settle in and group. These were shot with QYS 8.48 pellets.
I chronied with the Garmin Xcero.
IMG_7424.jpeg

Next I tried the AA 8.4's top row, then two more groups with the QYS bottom row, it started raining so I stopped shooting. But the chrony numbers sped up a little by the last two groups, so oring is settling in.
IMG_7428.jpeg

I think after some more shooting it will be good. Very solid shot cycle, and pleased with the effort. I don't want to do it again no time soon..lol. I forgot to check the piston latch rod runout, but I've done this in the past several times. I also need to touch up some bluing and wanted to make screw cups. And ultimately get a walnut stock of some sort.✌🏻

Huben  Huben GKI 22 caliber Pellets? any tight ones?

Is there any 22 caliber pellet that fits tight in the magazine ??? On my GKI Vi I have to seat each and every pellet, If I don;'t the pellet will jam my gun,, I can load JSB, H&N JTS even the GTO pellets have to be seated one by one, If I open the gate and tilt the gun up all the pellets will fall out, I call that a loose fit,, So is there any over size 22 pellets out there , I prefer light pellets as I keep my FPS down to 500FPS for crazy shot count ...

FX  I finally found the slug for .25 Superior 1:24

I've been trying to find a slug since April that performs great out of my .25 Dreamline's standard superior liner. By great I mean performs nearly as well as 25.4fx pellets in terms of accuracy... tried a QUITE A FEW. Nothing performed anywhere near as well as pellets, not well enough to give up the near perfect grouping capability of this gun with the 25.4 pellets. Why sacrifice MOA performance out to 100, 120 on a good day for some extra energy and range... Most shots aren't made at 120+... Best I got was H&N30... But at low velocity, pushing the 30gr past 900 from a dreamline sacrificed a lot of air. This weekend I got a bug up my butt and wanted to try one more slug. Hybrids were just OK, NSA didn't agree with my barrell, the original ZAN formulation was one of the worst performers, knockouts at 34gr was just too heavy. Then I saw zan changed the slug recently. (Recent to me). I bought a single pack of 28gr .250. holy crap. At 917.6 average. Hole on hole. This is at 50 and I'm holding groups no more than 10-15% wider than the AEA 25.3s I'm currently using as my new preferred projectile. I've seen the question asked before.. give the new ZAN slugs a try. Specifically 28gr .250. 915/920 is a good starting point. I tried them at 860,880,900 and 915... Every single increase tightened the pattern. I'm going to tinker a tiny bit more with pressure and velo. But actually excited. 40 ft lbs at 100y compared to 22fpe is huge.. still going damn near 800 at 100y

Snowpeak  Snowpeak M16

I just ordered a snowpeak M16 in .22. Really excited to get it and start shooting.

I am looking for suggestions on a scope to put on it. Main purpose will be small game game hunting and some target shooting. I don't want to spend a bunch on money on a scope but would like something decent.

What would everyone recommend?

RAW Rapid  RAW reg problem.? it's a Huma

I noticed my strings after cold shot were starting way low & moving up slowly with big swings, up to 25fps at worst. I fill from 210 & refill at 150+. The closer it gets to 150 the more consistent it gets but its a small window. The reg is a huma. Should I just ditch the huma & get a factory one from Martin ?. I'm using a .25 barrel with the big spring. The spring adjuster is working with a large fps swing for in & out. at least 50fps. something has to be wrong..could be me..lol The cold shot on this RAW is horribly slow, I don't know if this is normal as Ive only owned this one. Actualy the hammer spring will adjust maybe 80fps + the more I think on it. seems like alot.

N/A  Starter PCP one size fits all? : .22 vs .25 vs .30?

So... as mentioned in another thread I have somewhat outgrown my break barrel pellet gun, and I am overgrown with pests, ranging from gangster squirrels to raccoons. To date, I have used my worn out Gamo on starlings and squirrels, but my Gamo Whisper has a problem I don't care to chase and fix. So the new rifle, preferably regulated PCP is being discussed.

As I work through manufacturer and used v new details on the brand and model, I'm also trying to figure out the caliber tradeoffs. This is primarily a gun for "hunting" by way of pest removal. However, accuracy is absolutely mission #1.

Downrange energy retention comes in as a second, but still important.

So with that in mind...is there generic accuracy vs caliber guidance? I'm leaning towards a .25, as I have seen some solid performance reviews of accuracy for the guns I've been considering in .25

Is accuracy degraded for larger calibers? Sort of : Expect best performance for .22, somewhat degraded for .25 and more accuracy loss going to .30? IF so, how much? My squirrels won't know the difference between .35ctc groups and .50 ctc groups. But my raccoons would notice the difference between .22 and .30 at 30 yards. (I'm not hunting hogs, likely not coyotes). I do note that ammo selection for .30 is not as varied as for .22 or even .25

Sorry about the OCD flare on this. You should see me when I try to buy a new laptop.

My cat blew up my compressor

Well played, Monday.

TLDR: Need recommendations for a new compressor with a time / temperature emergency shutdown, or at least a way of avoiding this in the future. Also, my cat is fine.

For those who live to read spilled tea... here's what happened:

I woke up on this wonderful Monday morning with the usual heroic dose of middle-aged back pain, begrudging the morning school routine of shoveling kids out the door. I went downstairs to start the day, and was greeted by the smell of smoke, burning oil, and the unmistakable hum of my yong heng compressor.

My rotund tom cat - whom I keep in the garage at night - had stepped on the power button on his way to the food bowl, no telling at what time. It was obviously him, nothing else lives in the garage, and I had moved my compressor to a spot close to his bowl.

The garage was full of a hazy white smoke, smelled very strongly of burning oil, and my terrified cat was hiding in a drawer, poking his head up and crying out in feline terror.

Obviously the water cooling system wasnt on, though I never use it because I just fill my guns directly and that never takes more than 20 seconds. It also has an auto-shutoff, but because it wasnt hooked up to anything it never quit.

Common sense tells me not to trust the compressor from here on out, not unless someone here has experience with yong hengs being indestructible? I dont believe thats their reputation. Perhaps they are easy to rebuild, or perhaps it should be replaced.

-----------

Ideally I'd like a compressor that has its own integrated cooling system, and one that's smart enough to shut down on high temps or long runs. I'm starting my search, but I also want to ask real humans what their thoughts are?

Thoughts and recommendations?

FX  FX Impact M4 - 300 Bar - Needs First Regulator ?

I've placed my order for a new .22 FX Impact M4 and knew from much research and reviews already that FX have removed the 1st regulator, apparently the new brass pin in the 2nd regulator can handle higher reg pressures and so there is no need for the 1st reg anymore, it all sounds good so far.

When I was looking through the FX manual online I couldn't find much information with regards to fitting a 300Bar bottle to the M4, the information was getting a little hazy with no direct answer.

So I contacted FX directly and asked them if I can just install a 300bar bottle straight onto the M4 would that work or is something else required.

FX replied with:
"To mount a bottle with 300bar you need to install a first regulator that is mounted on the Impact M3. It has art no 20540 Bottle connector Impact M3 cpl. Also manometer for the first regulator. You see this on the exploited view on the Impact M3 here in section D F10370-Impact-M3-230925.pdf (fxairguns.com)"

So clearly from FX's response the M4 is not designed or supposed to have a 300bar bottle & fill, as the now only "2nd regulator" must not be able to cope with that pressure despite its new design / brass pin.

This is really disappointing, its essentially a downgrade and you now have to spend more money and time to reinstall the first regulator & manometer etc, just to get a 300bar fill on it, but on the M3 you could just screw set the pressures and put on the bottle, job done.

Whats everyone's thoughts on this ?

Hatsan  This could be one of the best $400 PCP pistols?

Really for this price how can you go wrong? While not as powerful as the Huben, it is certainly accurate and plenty powerful for the masses. Mine was registering 15 fpe in .22.

For those of you who wish to discuss consumer support, I chatted with Hatsan USA before doing this review. They wanted me to share that anyone needing support should use their Customer Support form linked here and not try to get ahold of them by phone. As long as you are within warranty they should be able to help you out, even send out parts if you are able to DIY.

Enough chatting, checkout my review below.👇
