Other than my CNC stuff I have let carbide finish for years. ( I am no good with sand rolls and no patients for it)

I know Lary has done a good bit of back to back testing and his results show more power with rough finish.

But again finish is way down on the list of important "stuff"

I sand rolled the chambers because I can do them quick and it looks nice. 😂

Should have just left them in carbide.
