Pointed slugs

I had a 375CT that was 34 pounds with a big muzzle brake. 350gr Hooker solids at 3250 fps. Between the brake and the weight the recoil wasn't bad at all. Not much problem hitting steel 2500 yards away.

When we went to finish load development at Ben Avery shooting range they kicked my friend who had a 375 like mine, and me also, out of the range, LOL??!!
I took her out today for a little testing. This is just the begins stages of testing just to see what she’ll run at.

Sorry guys didn’t mean to hijack your thread.

FX  Impact m4

Ok guys I made my mind up im ordering an Impact m4 600 mm in .30 cal what are some good pellets to start out with. Thanks. I have never owned a .30 cal pcp alot of .25 and .22 but never a fx or .30 can't wate lol
There aren’t really a lot to choose from. Try on the 44gr first and you probably won’t have to look any further. JSB and FX are the same. Compare to the AEA.

Moisture filter question

Yeah I understand what you are saying, but since I don't have a tank and will be filling the gun direct, would that change things? Also curious if there's a reason why you couldn't leave your filters charged for a day while you are using it frequently. This would obviously require check valves on both sides of the filter and a proper bleeding process to depressurize when finished, but my thought is that this would save you that 5 mins every time you want to top off the gun. Then again, doing all of this might end up adding up to the cost of a small storage tank...
I leave the tanks on my guns pressurized for months at a time. So, all things considered, I guess it would be OK to leave the filters pressurized for a day or two - something to consider.

Skout  Epoch HPR low max pressure after rebuild

Finally found the time to take HPR appart.
It seems that changing SK-OU7008 did the trick.

Thank you @manabeknives !

While I was at it, I changed SK-OU9003
Thing I don't understand is that what was wrong in the first place because I've changed ALL o-rings on HPR and LPR
Maybe something just didn't sat right...

Will it continue to leak remains to be seen...

FX Barrel Liner Indexing

dnye1986


The slug isn't pushed completely into the liner, only enough so that it sticks without movement. A slight push with the thumb is all it takes to do that. Since it's conical, it self-centers.
Once it's 'stuck' in the muzzle, then it becomes your marker for clocking, instead of trying to mark your liner end and erasing it with removing/reassembling the liner tensioner.
1.) Remove the tensioner from the liner/shroud.
2.) Mark the 'clock' positions on the side of the liner that is sticking out from the shroud (most go at least 4 clock turns: 12-3-6-9 o'clock for instance).
3.) Insert slug with the etched mark into the liner, NOT all the way in, just enough so that it doesn't move, and is in alignment with say 12 o'clock. It should be sticking out past the liner muzzle a tad.
4.) Reinsert the tensioner watching that the mark on the slug moves to the correct location (Top Dead Center).
5.) NOW, remove slug with tweezer (BE CERTAIN TO REMOVE SLUG BEFORE FIRING!!).
6.) CHECK TO ASSURE THAT THE SLUG HAS BEEN REMOVED!! Test fire to verify POI.
7.) Repeat until all four 'clock' positions have been test fired by moving the liner to Top Dead Center (12 o'clock to 3 o'clock, then to 6 o'clock, then to 9 o'clock) and aligning the slug mark to each new clock setting after moving to Top Dead Center.
8.) After getting the 'clocking' complete, decide which one is correct (normally the one that prints closest to Top Dead Center), then remove the marks on the side of the liner that don't work and leave the one mark that does (say it's 3 o'clock, so remove 12-6-9 o'clock marks).
From then on, after the need to remove your liner for any reason, always use that mark (the one 3 o'clock mark) to align with the slug mark and then tighten the tensioner to align to the Top Dead Center position (AGAIN, REMOVING SLUG BEFORE FIRING!!).
It's a little tough to explain, so if you still have questions, just ask or PM to clarify.

FX  FX M3 C1 ''TOP HAT'' issues

It’s been an issue for many many years. But it should never bite you again once you start working on the gun yourself. And if you don’t beat the piss out of the C1 with some dumb tune or use a flimsy little valve spring. Red loc-tite? Absolutely no freakin way. Chemically clean the threads and inside the C1, then use blue. If you clobbered the C1 so bad that you now have sloppy threads, replace the valve rod and C1 or whatever they are calling it now. I’m sure it has a new part number.
This ^^^
just another reason not to YouTube your Impact. The list of negative side effects is long.
Happy to see the OP digging in and finding and fixing on his own. great guns just not for the mechanically adverse among us.

N/A  Uragan or Veteran

I really like my Taipan Vets . I ordered a Vet standard in .22 cal a few years ago and liked it so much ordered another Vet short in .177 about a week later . I was impressed with how quiet , smooth and accurate they are . No need for an extra moderator that adds to length , at my power levels . They came with a single shot tray , 2 mags and extra O-rings. I picked them up for $1100 each and they are my main pesting airguns and occasional target shooters . A solid well build airgun, and for plinking in the back yard or shooting tiny groups I would bet the Taipan 2 would be a great choice.

fx impact m4 compact shroud length

hello to all new to the forum and was told this would be the site to ask questions
i have a fx impact m4 22 600mm and I'm looking at getting the compact barrel kit.

does anyone or could anyone take a measurement of their compact from the front of the picatinny rail where the shroud comes out
to the end of the shroud where the moderator meets.
looking for a different bottle configuration with the shorter barrel as i have a 480 and 580 cc bottles.
thanks for any help, seems to be a very informative site.

Dive tank question

Junk yard Bauer , now that was a great find.
Yes it was. I found it 25 years ago, long before I got into PCP. It sat in my garage gathering dust. It was just the pump. I then constructed a base mount and motor drive as well as all the controls, plumbing, electronics and safeties. These parts alone cost me about $1000, not counting my time. The takeaway here is that parts were still available. The compressor was manufactured in 1968.

Western Airguns  Bushbuck Carbine

I do not, but mine had the newer valve. Not sure on upgrades from the original design.

Tony P.
Ok thanks Tony. If you find out anything on Improvements, please post it. After Reading through the threads, your post is one of the only ones that I recall mentioning a new valve or improvements.

Umarex  Zelos arca rail

Yeah I get that, and it looks great with the M-lock bipod. I’m just saying if you’re planning on producing them to sell, a lot of people already have pic mount bipods so they may not be as interested know they would have to purchase another bipod for it to work for them.
That's a fair point. It could definitely be done as another option. I've redesigned the trigger guard to provide a ridgid mounting point for the lower rail anyway so having a lower pic rail option wouldn't be difficult. Honestly, I hadn't even thought about a lower pic rail other than an mlok mounted system. Thanks for the feedback I will keep that in mind.

Where to get Immersive Optics 5x30 Pro in US

As a current data point on this, I got the 5x30 Pro in four days from Optics Warehouse/UK. 45 min reply to question (posted in "blighty" business hours), UPS tracking number same day as order, and received on day 4. Still like the Element MRAD reticle a bit better, but the Immersive's Mildot is very nice, super sharp, fine enough for distance work, and wide/good range of illumination settings.

Sorry, @mschlee , you were had--mine came to $303...
