I explained the Compromises all 3 calibres make in a post above,
or to make it even simpler to understand, take every parameter of the shot .177 will win 1 or 2, but come last in others, likewise so will the .22, but .20 will be runner-up in every aspect & not come last in anything,
Which clearly makes it the best of the 3 compromises.
