Hahah i am currently shooting 30fpe with the 15 grain slugs 500mm dreamline. Im just waiting for some 21 grain wildmanslugs and 600mm barrel house for my new liner. Curious how hard i can push them

Standard .22 is 14gr. Jsb 18.1gr in .22 cal is called heavy kings. So why would someone want to use a 21gr in .117? 
whats next. 34gr .177? Lol

I’d try to get my hands on a few slugs first. I know a 24 grain won’t fit in the magazine because they are too long. Just for reference you should have no problems making 40fpe.

Some countries only allow .177
in my country you need a permit from the police and a gunsafe. Everytime i buy .22 pellets or higher i will need to send firearm documents to the customs
no regulation on .177

There are 34 grain and the very popular 25 grain RD in .22 pellets.
Why not an 20 grain .177 slug @ close to 1000fps?
I imagine the BC on such could be good.
How the FX .177 liners will handle 35ftlbf+ is of interest to me also.

Late 30's and I use a 600mm .177 liner, a 700mm .177 liner is being relased later this year, that may help a bit, tried all the larger TP's etc. didn't make any difference.

I have not seen the 600mm 177 fx in the USA market yet? But the Daystate electric hp do have a 600mm barrel that does well for high power nsa slugs. I have not heard much about 177 fx guns doing well with slugs? But I could be wrong!

I expect the M3 will make some pretty good power in .177 for sure, if you have the barrel length to do it. I've gotten my maverick with a non-FX barrel (machined at about 25" or 635mm) over 50 fpe pretty easily. I think it topped out a little over 1000 fps with with 24 grain Griffin slugs. I'll also note that was with Huma extra high pressure regs in the gun. I can't speak on the M3 magazines, but the Maverick magazine holds 23 grain .177 slugs easily, but will hold 24 grain with very minor modifications. It holds the 24 grain with no modifications, but they don't always cycle. They are right on the limit of being too long, but some minor dremel or sandpaper work will make them cycle just fine.
My Maverick has been modified for power a bit, but the M3 should be able to get very close in power bone stock.

What reg setting with the huma reg? I am worried that too high and i might break the valve seat

That was with my first reg at 200 bar and my second at 175-180 bar. I believe the M3 has a better flowing valve, and probably more heavily built than the one in the Maverick. I haven't had any issues with my valve, and I regularly run my gun at 170 bar on the second reg. I also have a heavier than factory hammer weight, so if one was going to break, I'd think I would have broken mine by now. I haven't been easy on my gun at all, because I've been pushing the limits on power in every caliber. Most of the time my reg is at 155-160 bar, and the gun is perfectly happy at that level. The M3 will handle it just fine too. I'm sure the M3 will make all the power you want at 160 bar,
