Just bought my first Binelli. A SBE, left hand. Took it to the sporting clay range for some fun. I read in the owners manual that I should shoot heavy loads for the first box or two to make sure that it cycles correctly. Today was my second trip to the range. The first time there I shot 200 rounds and had at least a jam every 10 shells. I did not give it much thought just hit it with a good shot of RemOil which didn't seem to help and figured it would get better with time. Today I shot another 125 rounds and this time paid more attention. I was shooting Winchester Super X 3.25 Dram and 1 oz of shot and I had at least one jam every ten shells. Very frustrating considering that I was told this was a great gun. You can pull the bolt back by hand and it will occasionally hangup on the way shut. It ejects the spent shell just fine but does not open far enough to load the new shell. I finally begged some 3.75 dram 1-1/8 oz loads and would fire it first and I never had another jamming incident. Do I need to be more patient until it gets broke in or is this going to be a continual problem with these lighter loads. I find this very frustrating. If the answer is to always shoot heavier loads what do I key on Drams or oz's of shot?
