For me anyway accuracy is the adjustment. If my particular ammo pellet , or slug shoots more accurate at a lower setting I just go with that.

HELLO.. if I’m not mistaken your rifle liner 600 is for slugs, let me explain, the twist rate on yours is 1:16, vs, king 500 liner is 1:24.To adjust my PCP rifles, I've always followed the methodology discussed and recommended many times on this forum, and honestly, it's worked for me. Since it worked for me, today I was at the club explaining this methodology to a shooter, and together we got the rifle working properly. So far, so good. But another shooter who was listening came over and immediately told me I was completely wrong.
The rifle in question is an FX King .22 with a 600 mm barrel. In my explanations, we start with a regulator at 75 bar, with the macro in position 13.
18 gr JSB pellets, and proceed with 3 group shots at position 13, another 3 group shots at position 14, and continue in this manner until reaching position 23. What I'm looking for is the smallest or closest group at 50 yards. At the 21 macro setting, we achieved near-perfect accuracy. We then used the stopwatch and measured the velocity at setting 21, which was 940 fps; at setting 22, it was 947 fps; and at setting 23, it was 948 fps. It was slightly increased with micro-adjustment, and the velocity did not increase.
From this, I deduce that with the macro in position 21 and making some micro-adjustments, the deviation can be slightly adjusted. In short, I copied my King's settings and applied them to this other shooter's. The differences are that mine, with the same pellet, prefers 937 fps, while this other guy's prefers 941 fps. And from 250 to 100 bar, I got 115 shots.

Well, I'm satisfied, yes, but this other shooter tells me I'm doing it very wrong, that I have a very low regulator and a soft hammer blow, that it's better to raise the regulator to 100/120 bar and have a stronger hammer, that I would get more shots, more consistency, that the regulator would work better, and I would recover faster. Honestly, I don't know if he's right, and I don't want to ruin my setup either, but I have a doubt. He's talking so confidently and he's getting me into trouble. Maybe he was just a conceited charlatan who wanted to brag about what he doesn't know.
Now I ask, which do you prefer? Would both settings work in theory, or which one is the correct one to achieve the desired FPS?
Low regulator and soft hammer.
High regulator and hard hammer.
I've oft times wondered about that. Our tanks require inspection but none of the supporting hardware does.Hello all,
Brand new to this sport, just bought my first FAC air gun and I have a few questions for you guys.
From what I've been told, in almost every country high pressure air vessels have to be Hydrostatic tested very 5 years (or so) with a "total lifetime" use of somewhere around 15 years (or so) which I'm good with for safety, but what about airguns like say an AirArms S510 or any other air guns that dosen't have a removable high pressure air tank.
Or say something like a water removable device like a "Tuxing water seperator" that are also charged to 250+ bars, or even the air whips we use to fill the guns/tanks?...
I wouldn't own them if they weren't
Agreed, I have the same and works perfectlyI have the GX E L3 dual battery compressor. This thing works great. I use it for direct fill to my BRK Ghost. Really good unit. I also have their new filter that I run with it. Both the compressor and the filter are outstanding.
I'm showing my age but beeswax does a great job of preventing fasteners from vibrating loose while allowing for manual adjustment.Hi.
Can anyone tell me what kind of pre-applied threadlocker e.g. Traxxas uses on their screws? That holds tight but doesn't lock up completely, and stays flexible and makes adjustments possible over time? It doesn't look like LocTite supplies any of this type of threadlocker, but clearly someone does. Anyone know or have any suggestions?

You’re going to get a wild variety of inputs but few will be based on the manufacturer recommendations or local / federal / international regulations.Hello all,

I have an early m3, my amp regs started to let go with reg 2 creeping 12-15 bar and then my 1st stage went rogue and maxed out the guage.I have owned my FX M3 for about 2.5 years with no problems. Never touched any of the settings. Went shooting the other day and when I filled up bottle, my #1 regulator pressure was the same as bottle pressure. Shortly after that, my #2 regulator started reading around 220 BAR. Called UTAH A/G, very helpful, and decided to bypass #1 reg and install a new generation second regulator (same as is on M4). Ill keep the forum posted about results.
Hi Timo,Be great if the hp& LP regs had numbered/click adjustment, would make experimenting and returning to original settings a lot easier.
Plus smooth over cap so you feel that you haven't messed it when carrying or supporting gun in hand.
Whats the longest shot typically and how small in those games? Just for my own bc curiositySomeone more knowledgeable with likely chime in but...
Just having that DRS PRO chassis is something that is a great benefit IMHO.
I'm imagining those top competitors have highly modified guns though so everything is optimized for these games. Just enough air and fps to finish one stage to compete at the highest level.
I can't remember which one, PRS or NRL, but one of these organizations prevented 25 cal slugs above 49 grains being used so that left the Altaros 22 cal 40gr King as a top pick because of the .21 G1 BC.
I'd personally choose the Altaros 60gr 25cal/.245 G1 BC if I had a choice for these games because I'm familiar with it's capabilities.
In order to achieve very low SD and ES you need to be very meticulous in your tuning approach. While the Mora is generally an extremely easy gun to tune, "fine" tuning will require some time and work. Currently during testing, I'm seeing 2-3 SD and as much as 14 ES depending on the speed and the pellet I'm shooting. However, for serious practice and competition, I will always return to the AEA 29.5 grain Center Punch pellets at 970-975 fps because that is where I get my best overall results. As a starting point for that tune I know exactly the 2nd reg pressure (100 bar) needs to be and the approximate position for the dwell adjuster (on my gun that's six holes from closed). However, because I'm using a 700mm barrel, your settings will be different(most likely a few bar higher on the reg), if only slightly.Really nice targets you got there!! What ES/SD are you getting? Mine is a .22 600mm and it shoots amazing! The only thing I don’t seem to get a handle on is the spread… ES 15-20 and SD 3-4 for me, would really like to get that tighter… dwell is also set fairly tight…
