I have the FX Dynamic 700mm in .357. To keep it short I’m looking to shoot a 145 ish grain slug and reach 900 to 950 fps. As of now after replacing the stock hammer weight with the 8mm hammer weight I’ve found myself at 170 bar on the regulator, macro/micro maxed out and shooting 830fps. Any adjustments, wether it be up or down in pressure along with macro/micro adjustments just drops fps. Is there anyone that can point me in the right direction or am I “pushing rope”? Thank you in advance.

I believe you are asking way too much of that air gun.
If bigger power is what you need out of a 35 cal you should be looking at AAA, Air Force, Western Air Guns or others who make higher powered 35’s.

Ok after some testing this morning here’s what I have. Pressure down to 160 with no other changes speed drops from 830 to 820 fps. Pressure set at 165 bar puts it at 832-834 fps which is obviously slightly faster than the 830 at 170 bar so that’s the sweet spot so far. The difference in air consumption from 165 to 170 bar is pretty big. Unless I’m missing something this seems to be what this gun can do.

I don't think that velocity will happen without some modifications. I was looking into the same model FX you have as a possible hunting/distance shooter here in Texas, specifically because of this video:
Around the 15:50 mark he tests some 160 NSA slugs and gets around 820-830 FPS, BUT he has a custom 800mm barrel supplied by FX which attributed to additional velocity (which is mainly what the video is about, definitely interesting).
Anyhow, I'm also interested in how you're enjoying the Dynamic?

Other than wanting it to be something it’s not I absolutely love it. It’s a tack driver with nsa 93 gr. Slugs. Fun target shooting and small game hunting.

Thats not bad at all. Honestly it cant reach 900 with that grain weight I bet. Its intended to launch fairly light 357 ammo. I feel like it falls short in the hunting category. I like to think 357 is meant to be a clear hunting caliber thats able to go deer size down to raccoon but frankly I wouldnt hunt a deer with the dynamic in 35. It could do a vital or headshot but I deem it the wrong tool. Coyote sure!

You would have to change to a pin probe and the other pice on the barrel it's not going to add that much I think some videos said 15 30 fps I'm not 100% what the exact amount is could be more

This ir the new AEA long range pcp .. it will come in .357 .. barrel length is 38" so it should do all the power need it .. and is regulated to .. I really hope they started to use the direccións that Donny give them in the red Panda . And this gun get to be flawless . Or as trouble free as possible.

your max is going to be around 230 fpe.. u will need a 800mm barrel to get more power but even then your only going to get about 250fpe

I have a 357 dynamic and I regret the power kit. It's made for hybrids. I have already been down his road and I am working on a hybrid only tune

Bro it's not worth it trust me. Air hog, 2 moa at best etc. just embrace the hybrid slugs and tap out. Dude I got discount heavy stuff for sale lol. For real tho 20 bux and shipping I'll send you what you want. Up north airgun guy is a cuck hold for utah airguns. He had fx personally helped him to get us to buy it. It was my dream gun. Now aspiring to get American air arms beast mode no ****ing around power

Any time you start needing a heavier hammer, in this case much heavier and you are hitting the valve against a plenum pressure considerably above the designed levels? Yeah you are hammering the crap out of it.
You may have noticed that when you added the extra reg pressure and the heavier hammer the shot cycle got a lot harsher. This is because regardless of what the YT influencers or others say, you are operating the gun far beyond it’s design parameters.
