New to this forum,have a question about where the spent casings are thrown-- My Arsenal (5.45) tosses them about 4:00, and my new plain jane Saiga 5.45 cases are closer to 2:00!! Is this a possible problem? They both shoot great and function fine, Arsenal has about 1500 rounds thru it the Saiga is new with 50 rounds thru. Any thoughts? Thanks!
