I probably put at least 20 hours total in the last Gunstocks Inc stock I did for my 204 Handi Rifle. Then I decided to start over, and put another 15 hours in it. Mine is a double palm swell target, walnut. No raised cheek peices, and no thumb hole. If you get that fancy, you're going to be putting that much more work into it.
It's worth it though. Beautiful stock.
I'd show you some pictures of it, but Hunt 101 decided to EAT all of my pics. As soon as I get more downloaded to this site, I'll post them for you.
