Getting ready to trim the basement and do the stairs.

All the trim will be oak.

I have always done my trim the old fashioned way, with a hammer and nail set. If I was using a hammer I would predrill the nail holes.

I was thinking of buying a Bostich 15 ga. finish nailer for this project. My concern is that it will split the oak trim. Is this a valid concern, or will the nail gun do fine?

If the nail gun will work fine, what length of nails is best for the casing and base? I was thinking 2".

Thanks for any advice.
