TJ spec and price guide?

Would be good to see 200 yard testing for the 1 in 20" twist Redman's rimfire liner.

The Lyman 225438 is NOT a .22 rimfire bullet.... It is intended for a gas check, not heeled to fit inside a rimfire case.... Heeled bullets (like the NOE 225-38-RN-CC1 or the RWS and Eley bullets have a MUCH longer stub to fit inside the rimfire case, and it is smaller in diameter as well.... 0.199" instead of 0.211" like the GC stub on a centerfire bullet....

For airgun use it's closest mold to .22lr bullet that we have in shape. 0.005" longer, 0.003" bigger in diameter and a bit different shank.

That said there are better .22x bullets out there so why copy .22lr when you can do better?

For the TJ's 1 in 20" .222 barrel the Neilsen 36 grain .223 (after sizing, of course) would be interesting. Same with Redman's 1 in 20" twist. Reason: the Neilsen 36 grain .223 is only .388" long and it is flatbase with smaller than normal meplat for an HP.

So perhaps that might be the beginning of an upgrade program for Huben K1......provided 1 in 20" also works at long range and in lower temps*. (Remember Huben K1 has a short magazine.....so the .223 bullets it uses are at most .428" long)

Other improvements Huben K1 needs is the regulator. Matt Duber has shown even in .22 caliber the stock regulator has too low of a refresh rate--->

Then there is the issue of getting Huben K1 filled to 350 bar (5076 PSI). (Cheap compressors like Tuxing exist that claim to be able to go to 400 bar....but then there still appears to be a widespread problem with people using non HP compressor oils like Royal Purple compressor oil in cheap chinese 2 stroke compressors......or even worse than Royal Purple compressor oil things like motor oil, ATF or ISO 46  hydraulic oil in cheap chinese compressors.)

*lowering temperature increases twist rate requirements.
