The other posts about the 200 grain Shockwave/SST are dead on. I use the 200 grain XTP which is a great bullet, but I'm not sure about shooting 200+ yards with it. I'd say it's a 150-175 yard bullet. For really long ranges you're going to want a pointed bullet with a high BC driven at high velocities. You'll also need a rangefinder. Another option are Dead Centers - I haven't tried them, but they look good on paper. I've heard reports about erratic accuracy from them, though.
