I have an FX Impact M3 in .22 (700mm barrel). Looking for a tune that will shoot FX Hybrid slugs that I can adjust the macro wheel to shoot JSB 18 grains as well. Just looking for a starting point.
FX Impact M3 slug and pellet tune
- Thread starter jdh2550
- Start date
Your starting point is finding settings for the Hybrids that your gun likes and produces the type of accuracy at the distances you want to shoot. Then you see if you have enough on the wheel to dumb the gun down for the 18gr pellets. You will only get to have one solid tune and the other will be a jacked up tune that might work good enough. Unfortunately if you want to attempt to be pellet/slugman, you have to focus on the slugs first. They require your settings to be perfect.

This is solid information that 
I agree with Vetmx. I have the same rifle & caliber as you jdh2550. I'm trying slugs around 25 grains and JSB Monster Redesigned at 25.39 grains. I'm focusing on the tune for slugs since I'll be shooting them out farther and the precision will be more important. So far it appears that 3 to 4 clicks down on the macro wheel gets to the diabolos to shoot well at the easier, shorter distances. I've found 995 FPS for the slugs and 970 for the pellets works well with the 2nd regulator at 110 bar, but YMMV.

Hybrids did not work very well in my 700mm std. barrel (nor my .25 cal either). They worked great in my std. 700mm .30 cal. barrel though. I tried a lot of slugs/weights/dia./brands and ended up with the 24.8 gr. - 0.217" Nielsen's. Might give them a try.

Thanks for posting this question. I actually created this account because I wanted to buy a used Impact M3 but being forced to post comments first has given me time to read a lot of useful posts like this. It definitely makes sense that you should tune for the ammo you plan on using the most.
