FX Seeking Recommendations for FX Dynamic .35

[MicMack]

Ok, before you all jump in here let me start by saying that I am fairly new to the air gun world here, please comment accordingly...

I have a question about how to eek out enough power on the FX Dynamic .35 700mm to reach a consistent >= 215 ft/lbs (if possible). As of right now, I have a stock configuration and have loved the performance/accuracy with 108 grain NSA slugs. I am on the wait list to purchase an 8mm hammer weight and am asking about what else I could do to bring up the power levels in hopes to hit that 215 ft/lb mark. Any ideas? The mythical 800 mm barrel? etc...

I also should state that I would really like to stay with this platform, I understand that I could simply purchase a more powerful single shot platform to ensure that I hit this bar but this is not ideal.

Thank you all in advance!

Well, I am glad that I am not the only one who has no ideas here... Thank you all for reading this post!

I can’t answer for the .357 dynamic but I would think that 215 fpe is achievable. I have an 800mm barrel on my m3 impact, tungsten hammer, Huma tuning spring and the reg cranked up and am getting 195 fpe with nsa 93gr slugs. Once they release the .35 caliber kit for the panthera/dynamic, I’m going to get it and put my 800mm barrel from my impact on my .25 panthera. Currently it has a 700mm barrel and added hammer weights and am getting 115 fpe with NSA 55.5gr slugs

Thank you for that Scott! I appreciate your input sir! I am on backorder for the 8mm hammer weight (have heard that the tungsten hammer causes damage on the Dynamic) and will look into getting the Huma tuning spring.

I’m not sure what the 8mm hammer weighs. I added a maverick hammer weight (13 grams I believe) and added 3 fx washers to it. I have a 700mm panthera .25 and am shooting nsa 55.5gr slugs at 1018 fps (127 fpe). These guns are capable of good power. The Huma tuning spring is the same as what comes in the panthera from the factory

At what reg pressure u run it ?

I have only gone up to 160 bar, but have been told that I could go a high as 170 bar without an issue other than lower shot count.

Well when you find out I also want to know I love mine I haven’t don’t anything to it I’ve tried every type of ammo and the 68 hybrids shot well for me but stock I’m only getting 143ft lbs the nsa ammo does good also but the 125 grain won’t fit the mag. I’ve been messing around with air guns for around 5 yrs but never got into tuning them

 

[MicMack]

@Beau15 - yeah, I have to single shot anything bigger than 108 gr. I would love it if someone has something 3D printed for the larger slugs but haven’t found anything yet

I seen a guy using one on YouTube but he had to rotate it with his finger after every shot and I use mine for coyote hunting so I don’t think I would like rotating it. I do know Huma is working on a caliber change and a few other upgrades for the 35 but rite now it doesn’t seem like there’s much out yet
