Barrel run in question

[Topshot]

I am looking to run in a new barrel using the fire one shot then clean etc, etc method for ten shots or so.

My question is should I only use a patch and solvent, or should I also use a bronze brush?

i.e. How would you clean between each shot?

The barrel is a Lilja
