Tuning Looking for Tips/Tunes for Taipan Veteran w/ 700mm CZ barrel

[Mink]

I have a new 700mm barrel and power plenum coming in and was wondering if anyone had any good ammo recommendations and tuning setups to share (reg pressure, FPS)?

I am not looking for record breaking FPE, just an accurate tune w/ JSB 18.1, RD Monsters, and/or slugs. Preferably getting at least 60-70 shots per fill (I am hand pumping). I feel that my LW "long" stock barrel underperformed with 18.1s at range, and was hoping that this barrel would be better with pellets too.

Thanks!

Summary... you can probably, if you haven't already, turn the reg down and get great results

Mine shot most accurate at 890 with 15.89’s reg set to 135bar.
Your mileage may vary.

My Veteran long 22cal is a little finicky with some JSB's 18's. Depends on which one's you get (JSB, FX, AA, Daystate), but it is dead money with the JSB 25.39's with either the JSB or FX version, and I mean dead money. I have it set at 40 foot pounds with a power plenum and a Huma reg set at 140 bar. You get 50 shots. It can go to 47 foot pounds but then you get only 30. I also am very interested in the results of the 700mm barrel, but only in the use of the 25.39's or really the 33.95's. If I went back to shooting 15.89's and 18.13 then I would set the reg down to 120 bar, maybe even lower with that long of a barrel, you should get over 100 shots per fill at 880fps, maybe even more with the right set up. I'm looking forward to hearing more.
