I saw a striped ramrod on a Hacker Martin rifle. He was contemporary or before NMLRA began. I would not use oak at all. Ramin used to be strong and good for arrows but some I ordered from a well known supplier snapped. Dogwood in the field can break at the bud scars. Ebon y and rosewood aren't always straight grain. Good old hickory is reliable only if straight grained. I've used a torch, potassium permanganate dyes, Fiebing's leather dye with success. Masking tape gets gummy when used with a torch. Good for painting on a dye.
