Well, I finally broke down and bought two inserts, .32 and 7.62x25, for my mosins. I have a ton of .32 for my nagant revolvers, and thousands of tok/cz52 rounds. Most of the feedback I have heard was positive. So I jam a .32 mag into the insert and pop it in my m44, because I want to try a short barrel first. According to the ad; "noise similar to a high-end pellet rifle." Ha! Maybe a high end air cannon. I then tried a .32 SHORT! Jeez. So much for target shooting around the house. I must admit, tho, the inserts work like a charm. The spent shells just fall out. I bet the toks are REALLY loud. Still, 30 bucks well spent.
