I've used a few (or tried to) back when I first started years ago, and seen several others, and the maple wood used simply did not impress me as to quality in general. A couple were maddeningly soft and fuzzy and just had to be abandoned. Again, perhaps I am a "wood snob".
My first rifle was done ages and ages ago (like 1995 or so, I think) with a precarve Pecatonica stock. I have since taken it apart but still have the stock here. It's pretty soft stuff. I even got another stock to redo the gun and kinda got disenchanted with the whole thing... maybe I shoulda got walnut... Later, I made this "barn gun" with a Pecatonica stock, and the wood was... ok. I would not even attempt to carve it. I tried to do another just like it, and the more I worked with the wood, the worse it got. Fuzz, fuzz, fuzz.
So, fuzzy got chucked.
I then attempted to stock a "musketoon" from a curly soft (silver???) maple blank, and even got it mostly done before I had to quit because I just couldn't stand it anymore! The wood just kept growing hair! Finally got the picture, and started all over with sugar maple and never looked back. I may or may not still actually have a curly silver maple stock blank here in the shop that I've had for years, but I wouldn't attempt to use it now even for a million dollars. (I can say that, knowing no one is really going to offer me a million dollars!
)
If I have painted with too broad a brush, I apologize. I have never been afraid to call 'em as I see 'em anyway, right or wrong, but I'm sure I have grown even more brusk and insensitive these past few years.
I still hold to my advice: If the wood is fuzzy when you try to cut, scrape, or sand it, it is no good. Try something else.
