7Green, sorry if this is the wrong place to ask but I was wondering your guns specs and tune. I just bought a FX Impact M3 700mm .22 caliber. I had purchased a .35 caliber barrel change kit, which for .35 cal it comes with a new (hammer and spring?). Anyways, I just put the barrel and pellet probe in and shot it as is without replacing the hammer/spring. Anyways, I was shooting 81 grain JSB exact pellets and at max setting ( knob above tank at 5.5, 1st reg at ~160, second reg at ~135/140, macro “wheel” at 16 and micro “thumb knob” at 5. All I could eke out was 750 fps (I used a crono). After seeing your power Destiny thread I noticed everyone else seemed to be getting 850-900 ish FPS with the .35 cal 81 grain JSBs. So I called FX and talked to Benjamin. He said he thought I needed to replace my current hammer/spring with the one out of the .35 caliber barrel kit, he said it was a heavier hammer that was meant to give more air/power. He also stated that if I did switch out the hammer, then I would still be able to shoot .22 cal just fine. I had to ask then why all FX Impact M3’s don’t ship with the .35 caliber hardware installed? It seems really silly to me to pay so much for a gun, then have to turn around and work on it right after purchasing it. Anyway, today I spent the day replacing the components. It took me a long time, but I finally got it all running…kinda. I now only get about 650 FPS at all the same settings as I mentioned above. I did notice that my macro and micro adjustments are a little off. The macro wheel will go to 16, but if I turn it more, it will click over to 01 and make the micro thumb knob jump. I don’t know if that is normal behavior as I did not mess with the macro wheel while shooting .22cal. And I have also noticed that my micro wheel will not go all the way to 5 now. Basically I can go to like 4.5-4.8, but if I go higher than that toward 5 then my gun won’t cock. I can still shuck the bolt, but it won’t catch in the rear position. These are just thinks I have noticed, I don’t know if any of this is normal since I am new to the FX Impact M3. Anyway, any thoughts or advice would be appreciated. I bought the gun from pyramid air, but since I worked on it and have shot it I don’t know if they would take a return or exchange at all. I could also try to send it to FX for service, but I don’t know how long all of that would take. I have really bad (in all honesty terminal) cancer and I am trying to enjoy my airgun as much as I can, not have it in the shop a month after buying it. So I don’t know what I’ll do. To be honest I feel like if I had not have messed with the .35 caliber then I would be golden. In .22 the gun was doing great and it was a laser. The only reason I wanted to do .35 cal was to kill a deer, then after that I was going to go strait back to .22 cal or possibly .25, but really prolly just .22. Anyway, I just feel frustrated and lost.
