Does anybody happen to know the twist rate in the 25 Cal and in the 22 Cal Airgun technology uragan standard? Also has anybody slugged there barrels and what is the measurements?

Thanks a lot, Rick

I have a .25 Uragan.and use 17.7 in my iStrelok Pro ballistic app. I forget where I obtained that info but know that I went searching for it like you and would only have accepted something from a credible source. I may have asked in the Facebook 'Uragan' group or emailed the manufacturer and received the answer from them directly.
