I have a uberti replica of a 58 remington army and have a couple of questions I put this together from a kit about twenty years ago and have shot it very little, the cylinder to barrel gap is only .004 so after firng about two cylinders through it I need to remove the cylinder and clean the front of it, is this normal? also just replaced the nipples and noticed that the flash holes are smaller my nipple pick wont even fit through them,how mutch of a problem will this cause or will I just have to shoot it and find out.
