I purchased an 1187 premier 12ga from wal-mart about a month ago and it is a jamomatic. It jammed a few times when I shot it for the first time and just yesterday it jammed a lot. By a lot a mean about every 3rd shot. I am kind of new to the semi-autos and I have been shooting very cheap stuff in my gun because I am just shooting skeet. I have been shooting estate and federal's cheap stuff. Is this normal for the cheap stuff to jam like this in a semi or is there definatley something wrong with the gun. I did fire some 3" turkey loads without failure, but in my opinion a 700.00 dollar gun should eat up everything for the most part. Anyone?
