If your Tec-22 works at all, Eagle 30 rounders usually function good too.
Also, perhaps aquire a 10 round Ruger rotary magazine and use CCI mini-mags to give an idea how reliable it is under ideal conditions...a proven mag with good ammo.
As good as Butler Creek 25s work in a 10/22, they don't in a Tec-22...I suspect the BC magazine, when compared to an Eagle 30 is missing the ejector protrusion located at the left rear feed lip.
Accuracy and reliability vary wildly with the Tec-22...I have seen only one of several examples that had both out of the box.
