From the experience you already have in this industry, I'm sure you know which discipline/sector is more viable, rough demand, and which to perhaps not even bother with unless you export.
I think that's a great start.
As a few posts indicate... it seems to take a long time to make a name in this sport, having your equipment win a few matches seems to help.
Seems stocks with a bedding block already in them, ready for people to swap their gear to is what would get the highest demand. Once people start having to send it out to a gunsmith, add lead time, this and that, I think a fair bit of the market is gone just because of the hassles. I've been playing with ideas of a chassis stock and attachments, and it is a bit of a pain trying to do something that does it all and fits a variety of actions/triggers and so on without having too many compromises.
Best of luck with the project.
