I was told that after you load your SBE and or your SBE11 you should press the drop lever to put a shell on the carrier for the gun to work right.The person that told me that has a SBE and he said thats what he had to do for the gun to work right.Also does the barrel from the SBE fit on the SBE11 or SBE11 fit SBE.Thanks for any help that I get on this matter,Boo
