I agree, I noticed an increase regarding shotgun action builds, it seems a lot of new builds are in progress, even on other forums people talk and discuss this kind of build. The book written by Ellis Brown seems to be in great demand. As mentioned previously I do think this is going to be the next best trend in rifle building. I even think there is going to be a supply of stronger shotgun actions developing to sustain this trend in the long run...some rifle part supplier will really do good if such an item can be provided at affordable price...the market surly is going to expand...this is my opinion....
