There aren't really all that many calibers.

.177
.204
.223
.243
.257
.264
.277
.284
.308
.313
.325
.338
.348
.358
.378
.416
.429
.444
.458


There may be a few others in there that I've missed.

Now, if you're talking about "cartridges" instead of "calibers", go find yourself a site with ballistics tables or reloading manuals...
