I don't actually own a Buckmark, but a friend of mine owns one and I have put several hundred rounds through it. The one thing I don't like about it is the fact that out of the 10 rounds it can take in the mag, 2 or 3 or even 4 sometimes are duds. Now keep in mind when I fire another box of .22 through another gun, no duds or only one or two are found. But this happens almost every single time I feed it another 10 rounds through the gun. Must be the one of 5 million sour Buckmarks!
