My SBE2 shot everything I jammed in it, light target loads to big magnums, never failed to work. I unfortunately sold it to pay some bills, you got to do what you got to do sometimes. I have never fired a Super Vinci, but they fit similar to a SBE2 and are a very nice gun, usually cheaper than the SBE2 as well.
I don't think you could do wrong with either gun for a quality hunting gun.
