In most cases I would refrain from using a wood ram rod as a stuck ball puller.
Many times the ram rod will leave some part of it's self, stuck in the ball and complicate a bad situation.
If you are hunting and unable to bring your range rod with you, follow exact loading procedures and you will rarely get caught with the ball loaded without powder, or the ball half way down the barrel.
If your rifle is .40 cal. or smaller, extreme care must be used with a wooden ram rod.
As far as a wood ram rod is concerned, if you don't have a hickory ram rod, GET ONE!
A maple, oak, birch, pine, spruce piece of wood will leave you stranded. Straight grained hickory is about the best.
Perhaps someone here can recommend a similar wood to use.
Going out in the field with a .36 call or smaller, you are better fitted with a brass ram rod.
