Re: burr on crown??
So do you(anyone) prefer to make the final crown cut with a charp tool, a piloted chamferer from brownells, or a polishing stone/lapping tool like mentioned?
I can see how the polishing tools (like those brass balls you spin in a drill with lapping compound in it) could push the bur the wrong way, into the bore kinda.
The 45 degree chamfering tool that uses a brass pilot seems good. Anyone try these? If you face off the barrel scquare to the bore, and chamfer with one of these, how could it not be a good crown after firing a few bullets past it.
And lastly, making the final(and every) cut with a sharp tool. Cant rememember if Carbide of HSS is prefered for this cut. But I'm just refering to putting that last little 45 degree touch on the actually crown.
