Or am I just overthinking this?

I assume, by "mini" you mean 2". Different loads develop different pressures, just like different 2.75" shells develop different pressures. You cannot generalize to all "mini" shells. I have a collection of tested loads, if you plan to roll your own.

Shooting shorter shells in longer chambers will also reduce pressure and velocities from what would be seen in a chamber properly matched to the shell. That difference will be greater with fiber wads than with plastic.

RST 2" shells were 6500 psi, but I do not know if they are still available.
