A rimfire doesn't foul with far more shots than that, at greater velocities along with burnt powder residue, also there are many centrefire rifles that don't get cleaned either, at even greater velocities still.

I still won't be dashing out for a smooth twist barrel.
Three EV2's that i know of have to be cleaned after 100-150 with Walther Barrels,it's not that uncommon.
