I posted this question to another forum but thought ya'll might have great input as well. I getting ready to start my .32 caliber Kibler SMR build and want to add a grease hole. I find a lot of pics showing various styles, I'm partial to the Gilispie oval shape. I know I can use a Forstner bit. I don't really like the imprint left in the bottom. I would rather shape the bottom of the grease hole. I am thinking of using a spoon carving knife. Does anyone have comments or suggestions?
