I have a Model 63 which after about 50-100 round the shells become really hard to eject and the cylinder doesn't freely turn.I have been told by people on the forum to bring a brush to the range and clean out the cylinders after about 50 rounds.Are you talking about a bronze brush or something else.With solvent? It seems like a lot of work.I am thinking about getting another 22lr either a Model 17 or Colt OM,Would i have the same issue of cartridges sticking and cylinder sticking in these guns? Is it a stainless issue or does it occur in blued 22 revolvers? Thanks all and Happy Easter!
