Sounds like you you need a ballistic program and a cronograph. I'd recommend the Ohler cronograph and here is a web site that will help you with some online ballistics,

I have no experiance with 220 grainers as I prefer the 240 grain Sierra HPBT. For every day shooting and hunting I set my zero at 82 yards, which makes me 2" high at 50 yards and 2" low at 100 yards. I use 9.2 grains of H110 with a CCI SR primer.

I have also been working on a 125 grain load, 2400FPS velocities are easly achievable but I haven't found a consistant load yet.

i also like the ohler and have had good results - well until a shed fire turned it into an artistic paper weight

this is an amazing idea. but what do you do if it's 125, 150 or 175 yards? do you have that all mapped out too?
