FX My shots become terrible after...

[JCNiest5]

There's something terribly wrong with my setup. Impact M3 22 cal. I was shooting Diablo Exact Jumbo Heavy 18.13 grains and accuracy was decent. I was using what FX gave me: Line 4, Macro Wheel 16, Micro wheel 2.6, 1st Regulator 150, 2nd regulator 87 (or you could say 90).

Now, I switched to FX Pellets 25.4 grains, the only thing (this YouTube guy said) was to change the 2nd regulator to 95. Did that, but now the accuracy is terrible.

What did I do wrong? What else do I need to change? I'm still new to tuning, so I'm not sure what needs to change.

Try micro wheel to 3.2

Reduce regulator to original pressure .

You reduced the speed by giving more weight on pellet and also increasing pressure on second regulator.

You mean the 2nd regulator back to 87 (90)?

Yes

 

[JCNiest5]

Yes

Okay, will try that tomorrow. When I first attempted to adjust the 2nd regulator to 95, I thought I had to screw in the safety screw (on the trigger assembly), and my ball-end 1.5mm allen-head screwdriver (the tiny ball-end) broke in the hole, so now it's stuck in there. I wonder what size is this screw? It's this screw (at 5:56 on this video):

I do not know how to safely return th regulator to 87-90.

Receive feed back from someone that knows how to do it.

The second regulator locating under the trigger is a 2.5mm Allen key. Dry fire the rifle and then turn it clock wise a quarter turn. Then dry fire 3 more times to see where the 2nd reg is at.

Try to keep a 25 to 30 bar gap between the first regulator in the second regulator. So if your second regulator is at 80 make sure your first regulator is at 105-110

My first regulator remains at 150 (it came that way from factory).

I know how to get it back to 87-90 using a 2.5mm allen key. Was just saying I broke my allen key adjusting the safety screw.

 

[JCNiest5]

I ruined the safety allen head screw, but now my M3 is dime-size accuracy at about 40 yards. Wait until I put the crosshair on a live squirrel and see what will happen. Stay tuned...

We will !

Keep us posted !

Good news to report. Got a few chances to go to the woods and glad to report, the accurate is really good up to 45-50 yards. After that, the drop is noticeable, but that's the best an amateur can do, I guess. Got about 5 squirrels to show for, but sorry, no pictures to post here. Happy PCP'in!!!

Now all you have to think for replacing the Allen screw in reg 2... You will need that if you want to explore your gun more

Actually, the reg 2 adjusting screw still works fine. It's the safety screw that got busted, but I already got it replaced with a stainless steel screw. My only issue now is the pressure keeps going down in cold weather hunting (I posted it on another thread). If I keep hunting in cold weather (like mid-40s), the PSI will keep going lower. I'm not sure how low it can go if I hunt the whole day. Two weeks ago, I hunted just a few hours and it went down from 300 BAR to 220 in a matter of few hours. And it was going even lower, but I went home. It's completely fine in warmer weather, but cold weather makes it shiver...LOL....

Another squirrel went down by my M3. What I found out is, though, with pellets, any twigs in front of the squirrel will alter the pellet in such a way that it misses hitting the target. Hopefully, with slugs, it has a little more trajectory to go through small twigs and still hit the target.

I had an issue (many years ago) when my paper targets at 30m went to sh1t.

I was shooting the length of my city centre garden and went from ragged single hole groups to perhaps three inches.

I spent ages working on the rifle (HW100), polishing the barrel, polishing trigger sears, noting pressures over a shot string. The works.

My garden range is over a pond.

Eventually I noticed that the bull rushes in the pond were peppered with holes!

A simple leaf is enough to deflect trajectory of a pellet.

Good luck with twigs!

Slugs will do almost the same thing.

No hope for me, then.
