I had two cylinders reamed (.45 colt) and can see reamer lines in the throats... should these be polished out and if so what would be a good method to do so...? any thoughts or suggestions would be appreciated...
How does the "after" compare to the "before"? When I had my .45 Cylinder done there were some tool marks in the throats, but not as many as in the original factory ones. Had I not looked at them before they were reamed I might have been concerned.
After several thousand rounds the tool marks have been burnished to almost nothing by the passage of the bullets.
I wouldn't be concerned with them unless by some fluke it doesn't shoot like it should. I'm pretty sure it will.
skip, Take a 4 inch piece of 3/8" dowel rod, cut a one inch long slit in the end 1/8" wide and put a small piece of #0000 steel wool in it and polish the throats out in a variable speed 3/8 electric drill on about 1/3 speed. That will polish out most or all of those reamer marks "without" taking any more metal out! It's just another way to "burnish" those cylinders. As a long time gunsmith, I have done this hundreds of times and have yet to "harm" a cylinder!...............................Dick :idea:
