I'd say it's a good way to start, but I for one wouldn't trust that rifle to a 200 yard shot on a deer without actually zeroing to to 200 actual yards.

I use the ballistic computations to begin the sight in proceedure at close ranges, since I don't have a boresighter, which will get me on paper. Then I back the target up to the range I intend to zero it at and actually shoot groups until the scope is adjusted. Then I shoot at a variety of ranges between and beyond the zero point to plot the actual trajectory. That way I know exactly where my bullet will be at a given range relitive to the line-of-sight.

There are too many things going on to rely on a computer to determine the zero for your specific rifle.

What you have right now, as far as I'm concerned, is a rifle sighted in at 25 yards. If you value clean kills I'd find a range that you can shoot out to your desired zero.
