I am just wondering why some people have problems with last round stovepipes and others don't? Seems like if it was a magazine problem we should all experience it. I for one have never had a stovepipe with either of the one's I fired. I sold the original one and got a performance Center. Not one stovepipe in either one. I used the magazines that came with them and also extra one's I purchased on E bay. I have also read other comments on this forum that say they have never had the problem also.
