Is this correct?

Looks about right to me... I ended up ordering a new block as it looks like the culprit may be a slight machining deformation on the valve seat (in my rifle), which impacts on the valve in a non-uniform manner, eventually leading to failure. On my third valve right now, 3-4000 shots in.

looking in Walthers site the only. 22 airgun barrel un- choked and the length AirForce is putting in the Slug-dor is 1-20" twist.
Not that they couldn't have ordered a special run of 1-16 with rimfire bore dimensions. I'd love that!

Edit on the Eagle claw velocity statement above.I just took it out. Velocity is 840 fps with the peanut. Don't know what I was thinking originally. Considering not being a slug gun , it's really not a bad shooter with Is that slow twist ans this short cast bullet.

It better not be a 1:20.
The 1:17.7 23.5” lapped out choke seems to do best with 28-32-34g max.
Really need a 1:16 or 1:14 for 40 grain RBT Griffin slugs

The Sinner .223 airgun always had the LW .22lr barrel with 16 inch twist and indeed i shoot it with the RWS .22lr 41 grain slug at the same speed as .22lr firearm.

750 is a Notos variant btw. If youre already used to shooting those distances then it should be no problem.

Hi, I have the RAW1000x also in 25cal. You said you are shooting slugs but you did not say what you had to do as far as barrel? I would like to shoot slugs with mine but my trials so far have not been going well.My gun shoots the AEA CenterPunch 33.9 very well but the same weight slug just won't make paper...?? I'm in Oregon.
Thanks
Bill

Im using the factory barrel, and the Altaros 50gr smooth slugs.

I’ve seen some really good deals there. All are above what I had intended on spending by at this time but you never know. Right now I gotta get to my 10 days here as a start

I have no need for a 30, but I am 100% sure that puppy will be packing some power,, WOW, My 25 caliber shorty is just over the edge in power , Shooting GTO pellets I can go from 1,300 FPS to 600 FPS in just a few turns of the power knob, I keep mime tuned to 600 FPS just for the shoot count and I don't shoot past 30 -35 yards with my pistols , Grackles, sparrows and Euro doves are about the only kills I have made with the GKl 25 caliber shooting the GTO pellets , Red dot installed and its been a huge learning curve shooting with a red dot but I think I am getting the hang of it.

Airguns of Arizona has a good variety of decently priced used guns. 30 day guarantee and leak tested before shipping out. Good option for saving money

I'm glad someone brought this up, because it was also part of the reason for the drawing, to show how much material has been removed.

You can see that, in the best case scenario, it is as thick as the cylinder wall at its thinnest point, where one of the outer o-rings is located.
However, in order to withstand the same pressure as the cylinder wall, a flat top or bottom should be at least three times as thick, which is not the case here at all.

They should have only removed the conical portion.
Then the bushing would have made sense too.

Sometimes we do things because we like to do them, we may pass on the things we like to do and have finished to others.The profit, as stated above, is to learn and share.

Why I query the Oring composition, RTI Arms has 3 Orings at NBR90, the rest NBR70.
300bar bottle, up to 180bar past the Reg.
It’s all to do with the groove/squish design.

Just a question in case there has been further advice in this regard.

First string testing he rifle on the 5 powers.
For a low powered rifle the flexibility is excellent for pesting both in and outside buildings.
Using JSB Jumbo Heavy .22.
Comparing the figures against HW100S at 7ft/lb, and HW100T at 27ft/lb, it gives me greater options for pellets and distances. It also shoots NSA 17.5gr slugs very well.
When I get it sorted I’ll be able to get some more tests done.

I hear you Martin.

What are you guys using for a backstop behind your targets when shooting your F4? I just bought one yesterday and have shot it once. I taped a piece of paper to a heavy duty collapsed card board box. I put a foam 1/2" 2 x 2 square exercise mat behind it and hung them on a shelf in my basement, on the shelf was a package of 1 dozen rubberized knit nylon mechanics gloves.
I took my first shot about 25 feet away from the target shooting a daisy pointed pellet. I hit the target eventho I couldn't hold the gun very steady. I went to see how deep it went through the cardboard, and the pellet went right through it, through the high density foam floor mat, and through 6 pairs of gloves. I bought hoping it would kill a squirrel. HFS! I'm blown away by how much power it has.

My new highscore 197/200 - 9x's

Hoping I can get to a 200 by the end of the year Still figuring out my best position at the moment. I shoot semi-bench, with a bipod up front and my rear hand supporting the buttstock.

August 12, 2025
FX Crown .22 500mm
Discovery ED ELR 5-40x56 FFP
JSB 18.13grain straight out of the tin à +- 900FPS
Distance: 30y
Wind: none, indoor

Raised any little dents, then I removed most of the finish, what little it had with a cabinet scraper and blocked it all out with 220. Next is apply stock oil with 400 paper to fill the pores

You never posted clear pictures of the wood. YET

gotta love em
