Hello Gentlemen:
I need to open the chokes of an old P. Beretta S x S shotgun.
The shotgun will be used for quail and dove hunting, but it have 0.020" of choke in the right barrel and 0.040" in the left.
I want to cut it and left 0.005" in the right and 0.010" in the left.
I have the proper and good quality tools (adjutable reamers) but the problem is that the inside barrels are chrome plated and the reamer simply do not cut.
Is there a way to remove the chrome prior to make the cut?
Please I really need good technical advise to perform this work on the shotgun.
Best,
