Which range to break in a shogun with buckshot?

[sigar15garandfan]

I presume that I shouldn't use the pattern board by the trap/skeet field to break in a new semiautomatic shotgun with numerous rounds of buckshot. However, I am not certain if I could use another berm area as a backstop for the shot rounds for the break in practice. I would be shooting approximately 200 rounds total to wear in the action.

Is there an area where that would be allowed that is not the shotgun area?

Yes, Range 1A or 1B may be used for this.
