[QUOTE="Trickymissfit, post: 550467, member: 25383"] It's actually pretty easy to embed a burr in the shoulder if you get into a hurry. Bad coolant or low coolant pressures will also cause you grief. Rarely is it the reamer itself, but usually the operator. I think it's time for all gun manufacturers to step upto the modern world and buy state of the art reamers from somebody that really knows how to make them. A typical Mapol reamer would ream a .223 bore to about +/-.0001" with a finish that looks like it was ground. I might add that you could probably ream 250 bores without ever touching the cutting surfaces with a grinding wheel. gary [/QUOTE]
