    I haven't decided yet – I might go to a local gunsmith or just rent some time on CNC machine.  My breech-barrel fit is quite simple to shave barrel down to 0.5" and put two o-ring grooves.

    Just rember TJ’s are barrel liner’s originally ment to insert into worn out barrels or if you want to change to a smaller CALIBER that’s what I remember anyway? Maybe they will customize for AIRGUNS? I would call them…

    I am gong to open a new thread/topic entitled "Lothar Walther Special Order, need 4 more for 30", .25 airgun blank, unchoked and .551 O.D. (14mm)" I got prices from LW for these specs.

    Did you take down the thread for Lothar Walther Special Order? Could not get 3 more?

    No, it should still be up and running, try here. I added your name to the list, I don't care how long it takes to get 3 more, I'm convinced it will be worth it. Remember, the barrels will come un choked, those who want a choked barrel can have the choke added by Steve when he fits it to your rifle. You then would get to choose how much you want it choked and for what distance, the advantages of custom work.

    Sounds good! Can we get this as a Poly barrel? and do you know what a poly barrel is? I don't.

     

    Thanks

    I also recommend to get get the thickest OD barrel you can 

    the ones from TJ are available in a 9/16 OD and then run a

    carbon fiber tube over that . If you going to make big power 

    I'd look into a product called " Limbsaver " this product can 

    take a gun that does not shoot well and by adjusting the harmonics

    with the Limbsaver you can get your rifle to shoot much better just

    by moving the rubber isolator to change the harmonics of the barrel .

     

    The thicker and stiffer the barrel the less you’re able to tune the harmonics

    Can't get the poly in the .551 O.D. so not an option but I asked Steve at Pomona once again and he recommended the standard rifling anyway. My best explanation of a poly rifling is a smoother, less sharp edges on the lands. Very similar to a Smooth Twist X. There are many different opinions out there of one versus the other but from what I have read there doesn't seem to be much of a noticeable difference between the two in how they shoot. It looks to me like the majority of the poly barrels are used in pistols. The technology has been around longer than standard rifling used today. As metallurgy and powders improved with time, the different rifling methods were developed to deal with the harder barrel steel and polygonal rifling was predominantly abandoned. Is there an advantage using a poly rifling in an airgun barrel? I'll leave that discussion to those who have used both, I have not. But I suspect the differences are minimal. I would guess that quality of the barrel would make more of a difference than type of rifling.

    I'm wondering what airgun platform you are going to use to achieve your goal of 1,100 fps .

    Here is my modified Wolverine 303 it is now a 22 cal with a Daystate 24" barrel in 22 cal

    this gun now shoots a 24 grain slug at 1090-1100 fps and does good , it also shoots a 40 grain

    very good and can easily shoot 1" groups at 100 yards .

     

    Here is the gun I was testing the DB on this day got 67db with the 40 grain slug at 935 fps

     

    Here are the 40 grain slugs in 22 cal

     

    Here are the 24 grain slugs that shoot 1,100 fps from a 1:18 choked Daystate  24" barrel . 

     

    Where do you get those slugs from?

     

     

    I make these swage slugs myself , if your interested send me a PM .
