Are you talking about a IPSC target or one of those huge B27s. If the IPSC/IDPA standard target, I will just say I can keep 10 shots strait into the 8 inch circle 'o' zone of the IDPA or the '5' zone of the IPSC one. That's the middle, not the whole target!
So, yes, keeping all the shots on the target, with apendature sights, one can surely do this, even with a unmodified poorly shooting Mini!
