This may be what the previous poster was suggesting by 'stab it with an icepick' (many times).
I inherited a couple rifles with stocks my dad had stippled himself. They look OK to me. It doesn't look like all that difficult, but he also was an amateur stockmaker and did a little checkering so I may be underestimating the required skill. I believe Gamo used to offer airgun stocks done that way.
