Paul, a flat would be more than ample. Let me look around here some this week to see what's available in a couple local hardware stores, that I've been told have a decent stock of ammo still. If I strike out I'll contact you about the details. I hesitate to accept such a generous offer, but will certainly front you the shell and shipping cost if we do this.

Thank you so much, SRH

May God bless America and those who defend her.
