Well, I have read that it was exactly that...too much of a handfull for most shooters...the Wildey and LAR are rather big...the Wildey a touch too expensive. For hunting, the 44 mag, 480 ruger, and 454 casull are plentifull and common. For target shooting, you don't really NEED that much to knock down rams...I own one in a 10" TC barrel....And I can tell you it can be pleasant like a 38 to shoot. BUT....I have some loads using H-110 that make it a monster...kicks harder than my 16 1/4" 45-70!!!
Only one manufacturer, Winchester, makes ammo for it. Thats about the limit to my knowledge of its history.
