I'm working on a Dickert kit from Track of the Wolf that is my first build. I mentioned in another post somewhere recently why I chose it over Jim Chambers kit. It leaves a little more inletting up to the builder and since this is more of a learning experience than anything, I wanted the extra work.
Now I say this never having built from a blank (not precarved) stock before, but it almost seems to me that inletting the barrel (mine is swamped) would be easier starting from scratch on a blank than trying to enlarge a channel that has been pre-cut on the small side. Once the stock is carved down to near-final dimensions, the barrel channel loses much of its stiffness and it is difficult to work with.
I wanted to at least complete a pre-carved kit before starting from a blank so that I'd have a rifle that is correctly shaped and proportioned to use as an example in the future. Would be real tough to do your first build from a blank totally from pictures without a real rifle available for study.
Anyway, just my $0.02
