BrokenKnife,
I'm in the process of buying a coehorn mortar and I'm looking for a place to shoot it locally. My father is retired and lives up about 30 miles north of Denton in the country. He has about 100 acres so I'm sure I can shoot my mortar there but don't know about a howitzer or gun. He has a few neighbors around. Have you found any other locations?
Adios,
TexasReb
