You can look through the attached .22 cal BC table, and see which domed pellets* have a higher BC (note that BC is variable with velocity, and every gun is a bit different, but those numbers are a good starting point). Those would be the ones resisting wind drift best.
With the very heavy pellets (say 25gr and over) you'd really need enough power to get them out there, 30FPE I'd say, your mileage might vary.
Also, there seems to be a tendency (cf. Bob Sterne's testing) that heavy pellets have a higher BC at higher velocities (850-900fps), where lighter pellets have their peak BC at mid velocities.
I'd buy a tin of each (or a couple of pellet samplers). During a time of low to no wind (at night with some strong flashlights?) I'd hang a large poster or two out at 100y, with a bunch of numbered bulls eyes, and shoot away.
FUN!!

*Note that the
Rabbit pellet and the
Piledriver both are extremely barrel picky, so I wouldn't start with those in your testing...
