Tight Cylinder chambers on a 744 Palmer made.

[pistolman44]

Just bought a used 744 last month. After fireing about 15 rounds 2 cylinders get tight and have to pound on the ejection rod on the cylinder to extract the empty fired brass. Should I polish the inside of these 2 cylinder chambers? Anyone here have this problem?

I polished the cylinders of my 357max many years ago when I had a similiar problem.  I used a dowel a few sizes smaller and wrapped some 600 grit paper til lightly snug and used a drill to slowly work from the back to the throats, careful not to taper the throats or you may create an accuracy problem.  If you saved one of your hard to eject brass; you could use as a guide to check your progress, that's what I did and when it slid in and out smoothly, I quit, haven't had a problem since.
