I think more electrics have "big" frets than acoustics, but I think it's to facilitate bending and other electric lead techniques. Your Blueridge probably has some setup issues, particularly saddle height and perhaps trussrod adjustment or one or more high frets, and a few tweaks should make it right. I suspect, from your description, that the action is too low. The BR 05 is a very nice guitar (I've played one), and other than a structural defect, can be made to play quite nicely. The problems are not due to fret size, for sure.
