Concerning the Tipped Trophy Bonded, it has been my experience that handloaders (and their stories/reports) are the ones who generate demand for boutique bullets among non-handloaders.

When the handloaders generate a "buzz" for a bullet, all the factory ammo users want in on the action. Selling to both fraternities gains exposure in two different markets at once.

I don't think pure factory users ever generate enough "buzz" to make handloaders try factory ammo (E. excepted in this case).

If the TTB is soft up front with ready expansion, it really does seem like about the best of all designs to me, but I'll probably never find out with the price they ask for factory ammo.
