Just out of curosity because I know just how much bore sizes can vary especally in certain brands I dug out some 250 Sabor Tooth bullets I knew were in my storage box and loaded one in the Omega then I wacked the butt acouple of good wacks with a heavy rubber hammer and pulled the breach plug I did it with out powder so I could tell if it moved and it did not.
There for I believe that the problem has to do with either defective bullets or the bore size as it is very hard to be sure which with out access to the gun in question I would suggest that any one using either Sabor Tooth or PB should make sure that they stay where they belong before trusting them.
