What is the practical limit of range for these cartridges for hunting?
to add to the excellent answer from Wyosmith, besides the skill of the shooter the specifics of the gun and the ammo make a difference.
In the modern era, the .30-30 & .32 Special are regarded as 150yd or less deer rounds, in average hands, in the most common rifles.
The typical Win 94 or Marlin 336 has sights that aren't well suited for long range precision, and while individual guns can be quite good, in general they aren't target triggers.
And the blunt nose bullets required by tubular mags impose limits of their own.
150grFP in a win/marlin carbine is the average standard
Shoot a 150gr Spitzer from a scoped .30-30 Contender or bolt gun and you have a different practical limit, for the average shooter.
And of course, there are fine shots, with decades of experience with a particular gun and load that can make good hits at frankly unbelievable distances.
