What is your end goal for this comparison? Ballistic calculators are only tools, and the old adage "garbage in, garbage out" does apply. Are you trying to pick a new rifle for a certain use? Just interested in rimfire cartridges? Wanting to learn ballistics? There are a lot of good calculators out there, but which one you use might change depending on what you are wanting to do.

Ballistic tables in general only apply to one specific loading (i.e. one certain product model from one specific manufacturer), so you'll have to do your own compilation work to be able to evaluate and compare loads.

I'm always more than happy to crunch numbers if you decide on a comparison you are interested in and want a little help.
