FX M3 600mm .25 lowest setting tune for maximum shots per fill

[DMoney]

Here are 2 groups of 10 shots each from 30 yards (max distance where I'm at).
These are FX 34 gr .25cal pellets.
I prefer slugs but am looking for a minimal tune for max shots to plink in the yard.
My settings are 1 on the big wheel and 2.25 on the QTS

Reg 1 at 130 bar

I haven't gotten a full shot count on a fill yet but as soon as I do, I'll share it.

Do any of you have results you'd like to share for a minimum power max shot count setting? I love the group and the info here is excellent. Thanks for sharing and reading.

I keep my 25 cal M3 2nd reg at 125lb. With the power wheel in the low numbers I get well over 100 shots in the 700 fps range with 33.95 grain pellets, which is nice for backyard practice (very low noise). I usually have power wheel up around 15-16 and fine power adjust around 3 for 865 FPS with the same pellets and same reg pressure.

Never really approached my .25 600 as a minimal tune. I had mine at 120 bar running 33.95 just over 900 fps. I forget exactly where my other settings were. I know higher than yours. I think the micro adjuster was like 3.5.

Around 3.5 is definitely ballpark at 117-120b on the second reg. I’m curious where the OP has his second reg set to be at 2.25. Especially with a 34gr pellet. Could probably nickname his gun ole slingshot. But if you’re only shooting 30 yards, who cares. That’s a lot of gun and pellet for plinking at springer/CO2 distance.

It's super easy to crank up the power.

That’s a cool little pig. As fun as they would be to shoot, I’m glad we don’t have them here.

It also looks like you should consider a heavier hammer spring when you’re on your “cranked up” setting. It will still let you adjust down for your back yard setting with a .25.

They definitely keep me entertained during the summer when I can't bow hunt whitetail deer. The pigs are super smart and harder to catch than deer.

I haven't gotten into looking at internal hop ups. Do you have any advice where I should start?

It’s not a hop up. Looking at your micro, you are just out of spring. Where is your second reg set when you’re maxed out on 5 with the micro?

Hmmm, lost interest already I guess.
