Great minds we have Eld.

Getting more performance out of a rifle you already own will always be a big hit. Heck, thats how Weatherby came to be. All Roy started off doing was rechambering customers rifles in exisiting calibers to his own Weatherby Magnum varieties and sending them back. Look where it took him! A fairly inexpensive upgrade will always be more popular than a totally new cartridge that requires a completely new rifle.

How many of us broke the 30/30s back out when Leverevolution came out? It completely boosted the performance capabilities of a ubiquitous and inexpensive firearm into a totally competent 200 yard deer rifle, and in places it is still fairly hard to come by in 30/30 for just that reason!
