FX FX IMPACT M4 SNIPER PELLETS & SLUGS .25 cal
- Thread starter Irish shooter
- Start date

Good to know the 1:18 is ok ,I will most likely be ordering one in the near future as I to will be sticking with the 34grain JSB or 33grain Zan slugs which I have been informed shoot very well .its a learning curve but keeps you on your toes , what does anyone think the reg pressure should be set at as general opinion is towards the 150bar from some dedicated slug shooters .I am currently set at 130 and getting 880fps with the JSB 34 grain

Hmmmmm, are they legal in Oz? Or would it be considered an illegal import by your overlords?

My 700mm Impact MK2 with lots of mods does ~1005-1050fps with Nielsen 34.9g at a 150-155Bar reg. It has room to go faster but I like my setups to be at comfortable tunes to keep them in good shape for the long haul. Im using a Huma hammer weight and spring for a little more hammer strike, but still pretty mild.
My good friend has a built Impact M3 with the same 700mm Heavy 1:18 Liner I have, and he runs about 170-175Bar to get the H&N Heavy slugs at ~1060fps. I cant remember if he has 44g or 46g slugs, but we got his rifle to be in the 1moa or just under range. Single Huma High Pressure reg setups are kinda the key to run these higher settings.

Well I think I found a small issue with the zan slugs
Seem to be a little bigger
Than the hybrids from fx
Also indexed the liner while installing the CF liner sleeve
Ran some jb through the choke of the barrel took the high spots down
As the pellets were getting grooved just as bad
Here is an after photo of a pellet pushed threw after
Doing the barrel pushes smooth now and very little hint of the barrel
Did this to my 380mm barrel for the notos as they was just as bad
Shot 2 groups of 12 on the 3rd group went from 3/4 down to a dime crono battery died so no other adjustments
But very happy with the poi now
Also didn't know there is an active air stripper Inside the shroud now I see why the mod is empty

FX liners have a reputation for being a little on the tight side, so the small diameters usually work best. Not all companies offer different sizes though.
There is an air stripper inside the FX shroud. I learned that the hard way by shooting 30Cal slugs through my 22Cal Shroud.

If I could find someone to ship to Australia and the shipping wasn’t too exorbitant I could probably get an import permit for them. Just that no one is importing them here at the moment.

Hi David, I'm just wondering how you're getting on tuning now. Have you upgraded the liner? Do you think you will be upgrading the hammer, too? I have been looking at the Tungsten hammer, which is around £80 online. i was out with the 26.5gr slugs last weekend but didn't have much success at 970fps.

It's those pesky air molecules, the ones you probably have too many of. Back off of the valve dwell / opening until things settle down. I believe, and I'm just going off of my last reading on my Mav. VP...I think...974 - 1040 It MAY have been my JSAR Raptor, I just grab a profile and shoot when I'm tuning. Anyway FAST is good, air is bad. I interchange the pellets and slugs with each other so my numbers are a jumble, like my mind. We have some wet stuff on the way so my shooting will be minimized. IF I get a chance today, I'll break out the Mav .25 VP and see what it does but we're supposed to have wet stuff for a week and the wife won't let me shoot in the house, how unreasonable can you get?

Hahaha gotcha, thanks!! Maybe I’ll send them a bit faster but if you could let me know at what speed they’re working for you that’d be awesome (once it’s dry again or your wife is seeing reason
- love the fact that I can shoot 40 to 50 and 75y out of my basement window).Upvote 0
we;; finally got this new superior heavy liner 1/18 pushed a couple of slugs through
felt good through the breech after that very little resistance until the last 2 inches then it gets real tight coming out.
.249 going in ends up .245 coming out. seems tight measured the barrel with calipers .245
