I have a SBE 1 that always gives me problem when the air temp is below 45 degrees. It cycles vary vary slow. the shell then don't go all the way up and misfires. So I bought a sure cycle, helped a little but still having problems. I clean the gun all the time. When I get done cleaning it there is no oil on it because I herd that Benelli needs to be dry when clean. the oil gets thicker and full of grit wich gives the gun problems. I shoot 3" BB and 31/2 BB that go 1550 fps so they are not light loads.What do I need to do.
