I recently bought a friends Rossi 720 (Interarms), he had three of them, all three were 3" stainless, full underlugs, one DOA, and the other two adjustable sights, one with smooth cylinder, one with flutes. I picked the fluted adjustable sight model. The only ammo I have loaded up are 250 swc going around 900 fps and don't want to use any of those. Thinking of a light cast bullet like 185 grain hp fb from Rim Rock and taking it easy on this Rossi (and me), something more comfortable. Does anyone have any experience with these Rossi 720's?
