I sold my Saiga. Fun but too expensive to shoot. Mine would only shoot high brass and with a 6,12, and 20 round mag. it got real expensive.
Mine cheerfully shoots high and low brass just fine. The only thing it doesn’t like is Winchester Universal. Then again, there are pump guns that don’t like Winchester Universal (let alone other semis) and it eats the Federal equivalent just fine so I don’t see that as a problem.
